PTFE - The Optimum ChoiceFor Hose LiningsSection from a PTFE Molecule,16 Angstrom Units long.PTFE, or Polytetrafluoroethylene, comprises long-chain molecules ofcarbon atoms, each linked to two fluorine atoms.The fluorine atoms provide a helical spiral which surrounds the carbonchain and protects it.It is this structure which creates the unique properties for which PTFE iswell-known.Excellent Chemical ResistancePTFE is renowned as the most chemically resistant material known. Onlya very few, very unusual substances and conditions can affect it, likeFluorine gas at high temperature and pressure and liquid, boiling sodiummetal.PTFE lined hoses can therefore be used for a wider variety of chemicalsthan any other hose type, making it the ideal choice for very corrosivechemical applications and multi-product applications.= Fluorine Atom= Carbon AtomNon-Stick SurfaceThe use of PTFE as a surface for cookware products has demonstratedto the world how easily cleanable PTFE surfaces are.This means that PTFE lined hoses can be purged 100% clean morequickly, easily and reliably than any other type of hose.Excellent Temperature RangeThe cookware application also demonstrates another of PTFE’s manyattributes - temperature resistance. PTFE itself can be used as a hoseliner at temperatures from -150˚C up to +260˚C, dependent upon thehose design and the application conditions.This is the widest temperature range of any rubber or plastic hose liningmaterial.Very High Electrical ResistanceMost aerospace electrical wiring has a PTFE cover, due to the excellentelectrical resistance of PTFE. This property is, however, a disadvantagein some hose applications where there is a risk of developing anelectrostatic charge inside the hose bore. Aflex Hose have developed anon-contaminant, FDA and USP Class VI compliant solution to thisproblem.Hose DesignThe only issue with PTFE as a hose lining material is the best way it canbe integrated in to the hose design. This is where Aflex Hose have aproven record of success over the last 30 years.Page 3

Aflex Hose and BIOFLEXPThe World’s Leading Manufacturer of PTFE Flexible HoseAflex Hose, founded in 1973, pioneered the concept of PTFE lined flexible hose for the transfer of process fluidsmore than 30 years ago.Corroflon convoluted PTFE hose and other types of PTFE hose, manufactured and supplied by Aflex, are usedby major Chemical, Pharmaceutical and Food companies worldwide.Over the years, hundreds of thousands of custom-built hoses have been designed and built to cope with themost difficult of operating conditions, and Aflex have continuously developed and expanded their productrange having pioneered and introduced Antistatic hose, Polypropylene Braided hose and many otherinnovations in response to customer demands.In 2001, Aflex fulfilled the most stringent demand yet.Conventional Convoluted PTFE LinerCustomers, worldwide, had always asked for the ultimate PTFE linedflexible hose... one product which incorporates the advantages of bothconvoluted and smoothbore designs. A product which is sufficientlyflexible, like convoluted, yet which retains the advantages offered bysmoothbore, like fast flow rate and cleanability.After years of painstaking research and development, Aflex launchedsuch a hose ... Bioflex.Bioflex is a smooth bore, highly flexible, PTFE lined hose. Its designovercomes the disadvantages of conventional smooth bore andconvoluted PTFE flexible hose designs, dramatically improving on manyof their individual technical performance parameters.The key feature of Bioflex PTFE hose is the PTFE liner design, whichcomprises integral rib sections which support the tube against kinking,vacuum and pressure, and highly compressed web sections which givea smoothbore inner surface and excellent flexibility.Another feature is the integral PTFE lined and flared end fitting design(see next page) which is available for all the standard end fittings onBioflex Hose Assemblies.Rib SectionWeb SectionThis provides clean, full-bore flow through the end fitting without anyentrapment points - unlike conventional fittings, which introduce a borerestriction, also a crevice at the end of the fitting tail.Bioflex PTFE LinerThis PTFE lining also protects the end fitting from any corrosive mediapassing through the hose bore.Today, Bioflex has become the established standard in process fluidsapplications all over the world, and continues to be introduced into newapplications every day.PBioflex is a Patent Protected ProductPage 4

Bioflex Hose - Special Test Programs (1)Bioflex has been designed to fulfil the most demanding of customer expectations and, as such, has been subjected to a highly complex and rigorousProof Testing Programme in comparison with competitive hose products.Test No. 1. The ‘Rolling U’ Test.Bioflex samples were run side by side with competitors’ products, including smoothbore FEP, PTFE or PFA lined Rubber hose products, and also smoothflex products, on a ‘Rolling U’ test rig.The 1” bore samples were “Rolled” at the minimum bend radius and at the maximum working pressure quoted for the competitor’s product.Results were as follows:lllRubber Covered Bioflex Hose - 1,500,000 cycles, no failure.- No leakage occurred, so test discontinued. No signs of damage, or wear.Competitor’s smoothbore FEP lined Rubber Covered Hose - 9,149 cycles to failure.- Hose leakage caused by severe failure of the hose liner, breakage of the helix wire and damaged rubber and braid.Competitor’s convoluted smooth flex type hose, SS Braid - 7,151 cycles to failure.- Hose leakage caused by very severe failure of the hose liner and braid components.These remarkable results confirm the claims made by Aflex, that Bioflex is the best designed, toughest and most reliable PTFE lined hose productavailable today.Page 6

Bioflex Hose - Special Test Programs (2)Test No. 2. The Permeability Test.Fixed lengths of Bioflex were pressurised to 30 Bar with Helium Gas,and compared with samples of standard convoluted PTFE hose.ResultsBioflex has more than 2.5 x the permeation resistance of standardconvoluted hose. Under identical conditions, the permeation levelswere:1” Bioflex = 138 millilitres of helium per metre per hour1” Convoluted = 371 millilitres of helium per metre per hourThe permeability, or diffusion of gases and some fluids through PTFE isa problem in certain, very specific applications. Bioflex hose offerssignificant advantages in such applications.Test No. 3. The Flow Rate Test.The test apparatus illustrated opposite was used to measure the flowrate of Bioflex, both in a straight configuration and coiled to its MinimumBend Radius. The test medium was water.ResultsComparisons were made with samples of standard convoluted hosewith the same diameter on the inside of the convolutions as the Bioflexinside diameter. These show that Bioflex is capable of delivering 2 - 3times the flow rate of convoluted hose, in both the hose configurations.Additional tests have shown that the flow rate through a Bioflex hose isactually greater than that of a convoluted hose which is one size larger.For example, 1 1 /2” Bioflex has a higher flow rate than 2” convolutedhose. It is therefore possible to use a smaller Bioflex hose, fitted with fullsize end fittings, to replace a convoluted hose more effectively, andmore economically!This remarkable improvement is due to the fact that the turbulent flowcreated by the convolutions in the standard product is virtuallyeliminated by the much smoother bore of Bioflex.Page 7

Bioflex Hose: Special Usage ConditionsCleaning & Sterilising Systems - CIP, SIP and AutoclaveCIP & SIP – PTFE liner tubes are chemically resistant to all CIP, SIP and Autoclave conditions. The primary consideration is whether thecleaning and purging cycle is likely to develop an electrostatic charge on the internal surface of the liner, in which case AS (Anti-Static)grade hose is required.AS grade hose and Electrostatic charge generating systems are fully described in the hose liner section.CIP systems using high electrical resistivity solvents like Toluene will require AS grade hose.Another electrostatic generation problem arises when wet steam is used, or when the cleaning fluids or WFI are purged out of the line usingnitrogen, compressed air or another gas, because droplets of liquid or water in the gas then generate a multi-phase condition until theyare cleared out, which will generate a static charge, and so will require AS grade hose.In static generating applications where AS grade hose is not acceptable due to the black PTFE liner, alternative solutions are available –please consult Aflex Hose for advice.Autoclave – Autoclave sterilisation does not normally involve any high flow rates through the hose bore, so static generation is not aproblem. Aflex hose grades GP and AS, with SS or HB braids are fully resistant to all autoclave conditions throughout the service life ofthe hose.The rubber covered grades EPDM, (RC) and Silicone Rubber (RC, SI) are able to withstand at least 100 x 30 minute autoclave cycles atrelatively high autoclave temperatures (upto 135°C, 275°F). Consult Aflex Hose for more specific information.PTFE Hose-Use with Alkali Metals, Halogens and Halogen containing ChemicalsPTFE hose liners react chemically with Fluorine, Chlorine Trifluoride and molten Alkali Metals.When PTFE lined hose is used to carry Chlorine or Bromine, either as gasses or fluids, they will diffuse into and through the PTFE liner wallthickness. Trace quantities will then combine with atmospheric moisture to corrode any braid/rubber outer coverings.Heavily halogenated chemicals, like Hydrogen Fluoride, Hydrogen Chloride, Phosgene (Carbonyl Chloride) Carbon Tetrachloride and otherorganic chemicals with a high halogen content can also be absorbed and transmitted through the PTFE liner tube.Other “Penetrating” Fluids and GasesSulphur Trioxide, Methyl Methacrylate and Glacial Acetic Acid are some other chemicals which can be absorbed and transmitted throughthe PTFE liner tube wall.Generally, however, as a hydrophobic (non-wetting) material, PTFE is very resistant to the absorption of chemicals. In some cases, PTFEhas superior resistance to diffusion, for example to the diffusion of automotive fuels, in comparison with all other plastics and rubbers.Gas/Fluid CyclingThere are some applications where the fluid passing through the hose turns into a gas, then back into a fluid, then into a gas etc, in acyclic sequence.This is normally associated with changes in temperature and/or pressure. For complex reasons these conditions are extremely damagingto the hose liner, whatever material it is made from.For example, hoses are sometimes used to pass steam, water, steam etc into rubber moulding presses, in order to heat the mould, thenrapidly cool it before reheating in the next cycle. Hoses of all types fail rapidly in such an application and PTFE lined hoses are noexception.Please contact Aflex Hose for further information if these conditions apply.Connecting Assemblies for Use in ApplicationsThe lengths of hose assemblies and their configuration in use when connected into the application must always be in accordance with theHose Configuration information at the end of this product literature.When being connected for use in applications, the end fittings on hose assemblies must be connected to correct mating parts in the correctway, using the correct tools, spanners, clamps, nuts and bolts etc. The connections must be sufficiently tightened to ensure that the jointis leak free but not be over tightened as this can damage the sealing surfaces, especially with PTFE lined and flared end fittings.In applications involving the transfer through the hose of expensive or dangerous fluids or gases, the hoses and connections must bepressure tested in situ before being put in to service. This should be done with some harmless media to 1½ times the maximum workingpressure of the hose assembly, as stated in the product literature.If in doubt please contact Aflex Hose for advice.Special ApplicationsAflex Hose PTFE lined hose products are not rated as suitable for use in the following, special applications:All Radioactive Applications involving high energy radiation, including Gamma radiation (degrades PTFE)All Medical Implantation Applications.All Aerospace Applications.Page 11

Bioflex Hose LinersGP - General Purpose LinerAS - Anti-Static PTFE LinerPurposeBioflex GP is the ‘General Purpose’ grade, for use in all applications wherefluids or gases are being conveyed which do not generate a risk of staticcharge development (see “AS”).Design & ApprovalsA full list of Approvals is given on Page 12.Bioflex GP is a virgin PTFE liner, manufactured from hose grade PTFE whichconforms to the requirements of:FDA 21 CFR 177.1550Bioflex GP hose liner tube has also been tested, and complies with USPClass VI, at 37˚C (99˚F), 70˚C (158˚F) and at 121˚C (250˚F) - see page12.Bioflex GP and AS PTFE Liner Tubes have also been tested for Leachablesand Extractables in accordance with BPSA recommendations, and werefound to be satisfactory.EC - ELECTRICAL CONTINUITY(Also known as “Electrically Bonded”)All Bioflex hose assemblies are electrically continuous, except Grade TO.Electrical Continuity requires that the hose assembly supplied is electricallycontinuous, or conductive, between metal end fittings at each end of the hose(whether GP or AS grade).The requirements for this are specified in the German Document BRG 132and EN ISO 8031:2009 Annex A, when tested in accordance with EN ISO8031:2009 Clause 5, which requires that the resistance between end fittingsshall be

Bioflex Hose BraidsSS - Stainless Steel BraidTO - Tube Only (no braid)PurposeStainless Steel braided hose is the general purpose product, and can beused in applications involving high temperatures and working pressures.High tensile AISI 304L stainless steel wire is used, to give maximumpressure resistance and external protection to the hose.PB - Polypropylene BraidPurposeTO grade hose (available in both GP and AS) is a lightweight hose, usedin applications where working pressures are low and where there is noneed for the physical protection offered by an external braid. TO gradetube is fully vacuum proof up to 212˚F. TO grade hose assemblies are notElectrically Continuous (‘EC’).HB - Hastelloy Braid (C276 grade)PurposePolypropylene braided hose is often preferred to SS in applications involvingfrequent handling and movement of the hose, and where temperatures arewithin the range -30˚C and +100˚C (-22˚F to +212˚F). PB braid is lighter inweight, and any broken strands will not cut the operator’s hands. In addition,PB braid is not prone to “chloride stress corrosion”, and has generally goodchemical resistance.To ensure *Electrical Continuity between end fittings 2 strands of Monel wireearthing strips are criss-crossed on to the liner, underneath the PolypropyleneBraid. These are folded back underneath the ferrule at both end fittings, tomake an electrical contact.NOTE: Prolonged exposure to sunlight eventually results in UV degradationof PB braid.PurposeHastelloy Wire Braid is used instead of SS where severe chemicalcorrosion conditions exist around the outside of the hose. One way inwhich this can happen is when Chlorine or Fluorine are being transferred.Diffusion of trace quantities of such gases through the PTFE liner canlead to atmospherically wetted fluorine or chlorine attacking the braidmaterial, in which case the Hastelloy Braid would be resistant.SpecificationsSame as for SS on Pages 9 and 10, except the Burst Pressures and theMaximum Working Pressures are both reduced to 50% of the SSpressures listed.KYB - Kynar Braid(Polyvinylidene Fluoride Monofilament)PurposeKynar Braid is used for the same reasons as HB above, but only inapplications where the reduced pressure and temperature ratings of KYBas listed are acceptable.Electrical Continuity is ensured by using the same design as for BioflexPB.Page 16

Bioflex Rubber CoversRC - Rubber CoveredFP - Fireproof Rubber CoveredPurposeFor the most rugged applications where the hose may be subjected torough treatment and severe external abrasion. Also for hygienicapplications, where the external smoothness and cleanability of the hoseis of prime importance.DesignAn SS braided hose assembly has a smooth finish, blue EPDM externalrubber cover extruded over and vulcanised directly onto the braid. EPDMhas excellent chemical resistance, and the hose has a temperature rangefrom -40˚C, -40˚F up to +140˚C, +284˚F (internal fluid) or +120˚C,+248˚F (external temperature). Black anti-static EPDM, and alternativecolours of rubber, and strips with alternative text titles are available tospecial order.SpecificationsPurposeAs for RC hose, but where the hose is also required to resist failure in theevent of fire, in accordance with Specification BS5173 Section 103.13part 6.3 (Fireproof). This specification calls for an 1100˚C (2012˚F) flameto be applied to the hose at minimum bend radius, maximum operatingpressure (water), and one end fitting under vibration. The hose mustwithstand at least 15 minutes without leakage.DesignAs for RC hose, but the red EPDM rubber is specially compounded to befire resistant. Black, anti-static EPDM Fireproof rubber is also available asan option to special order.RC-300 - Rubber Covered 300mm End ProtectionThe Blue EPDM rubber cover has been tested and conforms to therequirements of USP Class VI.SI - Silicone Rubber CoverPurposePurposeAs for RC hose, but where the hose may be required to withstandtemperatures from -73˚C, -100˚F up to +204˚C, +400˚F. SI grade hoseis semi-transparent, allowing visual monitoring of the braid, with a verysmooth external surface finish.DesignAn SS braided hose assembly has a platinum cured silicone rubber coverextruded directly onto the braid, with a very smooth external surfacefinish.SpecificationsThe Silicone rubber cover has been tested and conforms to therequirements of USP Class VI.In applications where excessive flexing of the hose at the end fittingoccurs, it is sometimes necessary to ‘stiffen’ the hose in this area, toprevent kinking.DesignA layer of rubber is applied and vulcanised directly to the ferrule, and300mm (12 inch) along the hose from the fitting. This can be done eitheron an SS braided hose (RC-300) or on a rubber covered hose as a300mm (12 inch) long double layer of rubber at the end (DRC-300).The rubber used is normally Blue EPDM, but if the hose is FP, or SIcovered, then the same type and colour of rubber would be used (DFP-300 or DSI-300).LimitationsCannot be applied to PB or KYB braided hose. If required for a PB hose,consult Aflex Hose for an alternative “EPR” system. (EPR includes a300mm (12 inch) length of loose rubber hose jubilee clipped to theferrule).Page 17

Bioflex External Protection SystemsKR - Kink ResistantSR - Scuff RingsPurposeFor applications where there is a risk that the hose might be severelyflexed anywhere along its length, and possibly kinked as a result. NOTE:The rubber cover hose has a “cloth” finish, not the very smooth finishnormally available.DesignKR is only available on hoses which also have a SS wire braid and arubber cover (RC, FP or SI). An SS reinforcement wire is helically woundon to the SS wire braid, then the rubber cover is applied on top of thehelical wire.LimitationsOnly available for sizes 1 /2” and above. Specifications as for the relevantRC or SI hose grade on pages 10 & 11.SG - Safegard Protection SleevePurposeFor medium duty applications where the hose requires some protectionagainst abrasion when dragged over the ground, but where a full rubbercover would be too heavy and cumbersome. Also for PB and KYBbraided hose, which cannot be Rubber Covered.DesignSpecially moulded abrasion resistant rubber scuff rings are placed everyhalf metre along the hose.LimitationsAvailable for hose sizes 1” (25mm) to 2” (50mm) only. The operatingtemperature should not exceed 140˚C (284˚F) (internal).PC - Protection CoilPurposePurposeTo protect the hose against external abrasion and mechanical damage. For For applications where the hose requires protection against abrasionuse in applications where maximum external protection is required with when dragged over the ground, but where any rubber reinforcement isminimum extra hose weight. Particularly useful with PB or KYB hose, where a not permissible due to temperature, chemicals etc.rubber cover is not an option.DesignDesignA lightweight black, HDPE (High Density Poly Ethylene) strip spirally wound A stainless steel wire helix is wound onto the braid and welded to thearound the outside of the hose over its whole length, secured to each end ferrules at each end.fitting by crimping under a SS ferrule.LimitationsLimitationsAvailable for all sizes and Grades of Bioflex Hose.Safegard is applicable to all hose types and all hose sizes from 1 /2” up to 4”.Safegard is limited to use within a temperature range from -40˚C (-40˚F) upSpecificationsto +100˚F (212˚F).

Bioflex Sanitary Triclover Fittings, PTFE Lined and“Beaded”End Fitting Specification- BS4825 Pt 3 (UK)- ASME BPE-a-2007 (USA)- DIN32676 (Europe, DN Sizes)- ISO 1127 (Europe) (Non Standard, Specials Only)End Fitting Materials- Fittings in Grade 316L SS (= BS 316 S11 = EN 1.4404)- Ferrules, most in Grade 304 SS, some sizes in Grade 316L SSTemperature and Pressure Ratings- Pressures up to 16 Bar (230 psi)- Temperatures up to 180˚C (356˚F)- Higher Pressures possible with Special Clamps.DescriptionIn this new design, the PTFE hose liner tube is extended through the Triclover end fitting and is flared over the sealing face. It is then hot-formed to conform tothe shape of the rubber seal and therefore replaces the rubber seal.This includes the ‘bead’ shape which is used for concentric location of the seal to the mating components when a joint is made as shown in the drawing.Advantages of the Bioflex PTFE Beaded End Fitting- After connection, the PTFE does not ‘bulge’ into the bore in the same way that a rubber seal would. This rubber bulge interferes with the flow path and cancause material entrapment but these problems are eliminated by using the new design.- The need to ensure the compatibility of the rubber seal with the media passing through is no longer a problem, due to the all PTFE sealing system.- The joint includes only one sealing face not 2 as with the rubber seal.- The internal section of the moulded PTFE seal, which is squared off to provide a closed sealing edge in the joint, ensure no crevices in which materialentrapment might occur.- If hoses are required to be joined together then the Bioflex PTFE Beaded Triclover End Fitting can be connected to a standard Bioflex Triclover Fitting toprovide an all PTFE joint between the hoses.Nominal Hose Size Nominal Pipe Size Flange Diameter D Outlet Diameter I*Fitting Length A(Bioflex RC)in mm in mm in mm in mm3/4 20 DN201.340 34.0 3/4 19.0 2.56 657/8 22 1”1.984 50.5 7/8 22.2 2.60 661 25 DN251.984 50.5 1 26.0 2.84 721 3 /8 35 1 3 /4”1.984 50.5 1 3 /8 34.9 2.84 721 7 /8 48 2”2.521 64.0 1 7 /8 47.6 3.31 84*Fitting Lengths listed are for Bioflex RC, SI and FP hose grades.

Bioflex Steam Heated Hose Assemblies.(CH Grade)PurposeFor use in applications where the temperature of the process fluid must bemaintained as it passes through the hose. This is usually required to preventsolidification or an increase in fluid viscosity. Steam heating is preferred toelectrical heating in some applications for reasons of availability or safety, butis less controllable.DescriptionThe heating element comprises a small diameter PTFE heating hose, 1 /4” or3/8” bore size, with a single SS wire braid. This is spirally wrapped around theCH Hose Assemblyhose, with inlet and outlet ports attached, either both at one end or at oppositeends of the hose assembly. In the case of hose assemblies longer than 3metres, it is usual to have several heating hoses with inlet ports at oppositeends and along the hose. This reduces the effects of temperature loss overthe length of the Hose Assembly. The thermal insulation is usually closed-cellsilicone foam rubber. The outer cover is a SS wire braid with a rubber cover ifnecessary.Inlet/Outlet forSteamConnectionSmall diameter PTFE heating hose, coiled along hoseSilicone foam rubber thermal insulationOuter braid, or other protective coverDesignEach hose is custom designed and built to suit the requirements of theparticular application.

Self regulating elements mayrequire a sensor and controller if a specific maintain temperature is required.Please consult Aflex Hose for clarification. Resistance element heated hosesusually also require a temperature sensor to be built in to the construction andmust be used in conjunction with a temperature controller. The power leadsand (if applicable) temperature sensor leads emerge from the hose assemblyat one end, through glands and conduits. The thermal insulation is foamrubber, silicone foam rubber for temperatures above 80˚C (176˚F). The outercover may be a polypropylene yarn or SS wire braid with a rubber cover ifnecessary.Silicone foamrubber thermalinsulationTemperature sensorOuter braid, or otherprotective coverHeatingelement coiledalong hoseDesignEach hose is custom designed and built. Application details must besupplied by filling in an “ETH Hose Questionnaire”, available from Aflex Hose.Generally, for Hazardous Areas, particularly “ZONE 1”, the Self Regulatingtype of heating element is employed, with or without a temperature sensorand control, and flameproof glands and conduit are also required. The wattsper metre of the heating element, the pitch of the spiral on the hose, and thethickness of the thermal insulation are all calculated in accordance withestablished formulae to give the required maintained temperature.SpecificationsAs for Bioflex GP, SS on pages 9 and 10, except that the Minimum BendRadius is tripled and the outside diameter and weight are significantlyincreased in line with the particular design.

Bioflex Standard and Puretag Labelling and ColourCoding SytemsStandard LabellingAll Bioflex hose assemblies are labelled with the following information:- Manufacturer’s Name (Aflex Hose USA, LLC)- Hose Size and Grade- Max. Working Pressure- Unique Serial Number- Month & Year of Manufacture- Aflex Hose Telephone Number- CE Mark (if applicable)This information is normally vibro-etched on to a loose stainless steelRing mounted on the hose.In some cases, at the discretion of Aflex Hose, the information may beetched on to a thin stainless steel plate which is clamped to the hose, oron to the end fitting ferrule at one end. This may be necessary forexample, if the customer requires additional information which may not fiton to a Ring.Customers may specify which labelling system they require, and mayrequest additional information on the label.Puretag Labelling and Colour CodingThis system is only applicable to the EPDM (RC or FP) or Silicone (SI)rubber covered grades of Corroflon.A label and/or Colour Code is encapsulated on to the braid by atransparent rubber cover which is integrally vulcanised and fully bondedto the rubber cover on the hose.Another alternative is an RFID programmable tag, encapsulated in theRubber (Aflex Hose “Flowtag” system) - consult Aflex Hose for details.Further information is available on the Puretag product informationdocument on the website.Colour CodingThis system is applicable to all grades of Bioflex hose.A coloured PTFE spiral strip is wound on to the hose.It can be left loose, or it can be encapsulated under a transparent, heatshrunkpolyolefin sleeve.Page 36

Correct Hose Configuration& Length Calculations - for Bend RadiusHose Configuration RequirementsHose Assemblies are usually connected at both ends in service. They may then either remain in a fixed, or static configuration or in a flexing, or dynamicconfiguration.Whether static or dynamic, the First Rule concerning the configuration of the hose is that the bend radius of the hose must never be less than theMinimum Bend Radius (MBR) for the hose as listed in the relevant hose brochure.The most common situation when this is likely to occur is when the hose is flexed at the end fitting, with stress being applied to the hose at an angle tothe axis of the end fitting. Typically, this happens either because the length of the hose is too short, or because the weight of the hose plus contentscreates a stress at an angle to the end fitting.The Second Rule, therefore, if possible, is to design the configuration to ensure that any flexing in the hose takes place away from the end fittings.(DYNAMIC) CONFIGURATIONINCORRECT - Hose too shortLess than MBR(STATIC) CONFIGURATIONINCORRECT - Weight of hose is at 90˚ to Axis of End FittingsLess than MBRCORRECT - No flex at end fittingsCORRECT - No flex at end fittingsOR90˚ Elbowend fittingsPage 37

Correct Hose Configuration& Length Calculations - for Abrasion & TorqueThe Third Rule is that the hose configuration should always be designed, and supported where necessary, to avoid any possibility of externalabrasion.In some cases, the length, configuration and angle of the hose can be designed to avoid abrasion. In others, static or moving support frames or support wheelsare required.AbrasionIncorrect - Hose abrasion against hose)Incorrect - Abrasion inside supportCorrect - No hoseabrasionCorrect - No abrasion over supportThe Fourth Rule is that the hose must not be subjected to torque, either during connection, or as a result of the flexing cycle.Torque (twist) in the hose can be applied during connection if the hose is accidentally twisted, or if the second end being connected is a screwed connection,and the hose is subjected to torque during final tightening.In a flexing application, if any flexing cycle of the hose occurs in 3 dimensions instead of 2, then torque will also occur:CORRECT - Flexing movementtakes place in 2 dimensionsINCORRECT - Flexing movement takes place in3 dimensions, so torque is appliedBoth Corroflon and Bioflex hose have good resistance to a small level of torque, much better resistance that rubber or SS hose types, but it is still the best practiceto take whatever steps are necessary to eliminate torque. If in doubt, consult Aflex Hose.Page 38

Hose Configurations & Length Calculations- for Length CalculationCalculating the Hose LengthThe formula for calculating the bent section of the hose length around aradius is derived from the basic formula that thecircumference of a circle = 2πR, where R = the radius of the circle, and π = aconstant, = 3.142.So, if the hose goes around a 90˚ bend, which is 1 /4 of a fullcircumference, and the radius of the bend is R, then the length of the hosearound the bend is = 1 /4 x 2πR. Or half way round, in a U-shape, = 1 /2 x2πR.RL = 1 /4 x 2πRNote :In calculating the length of a hose assembly, the (non-flexible) length of theend fittings must be added in, also the length of any straight sections ofhose, as in the following example:Example :To calculate the length for a 2” bore size hose with flange end fittings, tobe fitted in a 90˚ configuration with one leg 400mm long, the other 600mmlong.RLength of Bent Section (yellow) = 1 /4 x 2πR (334)= 1 /4 x 2 x 3.142 x 334 = 525mmL = 1 /2 x 2πRLength of top, Straight Section, including the top end fitting length= 600 - 334 = 266mmLength of bottom end fitting = 66mmTotal length of Hose Assembly = 525 + 266 + 66 = 857mmThings to consider(a) A hose will normally take the longest radius available to it togo around a corner, not the MBR! Also - always remember toinclude the non-flexible end fitting lengths.600 - 334= 266mm600mm334mm(b) In dynamic applications, remember to always calculate thelengths for the most extended configuration during the flexingcycle, not the least extended.R = 334334mm400mm(c) If the configuration is simply too complex for calculation, thenRADIUS R = 400 - 66 = 334obtain a length of flexible tubing of some kind, mark on paper,or a wall, or floor, or both where the connection points will berelative to each other, scaled down if necessary, then manuallyrun the flexible tubing between them with full radii roundbends. Measure the extended length, then scale up if necessaryto determine the approximate length of the hose.End Fitting Length = 66mmIf in doubt, consult Aflex Hose.Page 39

GeneralAflex PTFE hose products have not been designed or tested to be suitable foruse in any Aerospace, Medical Implantation or Radioactiveapplications and such use is therefore strictly prohibited unless writtenapproval from Aflex Hose USA, LLC has been given.Aflex Hose USA, LLC will not accept liability for any failures of the Aflex HoseProducts which are caused by customers failing to perform their Responsibilitiesas specified in these Conditions of Sale.It is the customer’s strict Responsibility to review all of the usage limitations givenfor the hose which he intends to use in an application, to ensure that theapplication conditions are in compliance with those usage limitations. The usagelimitations are specified both on this page, in the Full Brochures for the relevantproducts on the Aflex Hose website. Customers must always consult the latest,up to date information, which is only available and downloadable from the Aflexwebsite.It must be accepted, however, that the usage limitations specified elsewhere inthe Hose Product Information and on this page are intended as a guide only,since every possible factor in every type of application cannot possibly becovered. It is therefore the Customer’s Responsibility to ensure the designsuitability and safety of the products in their intended applications, givingparticular consideration to the chemical and electrostatic compatibility of thefluids or gases passing through, the possibility of diffusion of fluid or gasesthrough the PTFE hose lining, the possibility of external corrosive conditions, thetypes and likelihood of excessive mechanical abuse, such as abrasion (internalor external), crushing, excessive flexing or vibrations etc, and any excessivetemperature and/or pressure “pulsing” conditions, all of which may causepremature hose failure. It is also the Customer’s Responsibility to consider, andtake account of the degree of risk involved in any hose failure, including theprovision of adequate protection in the event of any risk to employees or thegeneral public. In applications where any type of hose failure would lead tofinancial losses if the hose is not replaced immediately, it is the Customer’sResponsibility to order and hold in stock spare hose(s) accordingly. It is also theCustomer’s Responsibility to advise Aflex Hose in writing if there are any specialrequirements for the hose, including cleaning, or drying, or extra testingrequirements which are in addition to normal industrial standards.If the Customer has any doubts concerning these or any other usage limitationor safety parameters, it is the Customer’s Responsibility to consult Aflex HoseUSA, LLC, to request a written response to any queries.It is the Responsibility of the Customer to ensure that if the product is sold on, orpassed on, however many times, that all the necessary information including thispage and the Aflex Hose website address are also passed on to the final user,together with a specific requirement that the final user must review the usagelimitations in terms of his own application.Hose Service LifeIt is not possible to guarantee a minimum service life for any of the Aflex Hoseproducts which can be applicable for every type of application.(For example, PTFE lined hose has been used in one application where it wascycled with hot steam, then cold water, also flexed every 17 seconds 24 hoursper day, and the customer was very satisfied with a service life of 3 weeks beforefailure. In other light duty applications carrying pharmaceutical products,however, many Corroflon hoses are still performing satisfactorily after 20 years inservice).Service life predictions or guarantees can only be given in cases where all therelevant information concerning the application is given in writing to Aflex Hose,and Aflex Hose subsequently replies in writing prior to the order being placed.If such a written undertaking is not sought and given, then Aflex Hose cannot beheld liable for any hose product failure which the customer considers to bepremature, excepting failures which are due to faulty materials or manufacturingdefects.24 Month WarrantyAflex Hose USA, LLC warrants its products to be free from faulty materials ormanufacturing defects from the date of the initial sale, for 24 months.N.B. All ETH hoses are only warranted for 12 months.Conditions of SaleProduct FailureIn the event of a product failure, Aflex Hose requests that the product should notbe cut up or tampered with, but should be de-contaminated and returned toAflex Hose, plus a decontamination certificate, for examination and analysis ofthe fault. The customer should also provide full details in writing of theapplication conditions under which the hose failed, including Pressure, Vacuum,Temperature, Flexing and any cycling of any of these, also the fluid and gasespassing through the hose, and the total time that the hose has been in service.The customer may send his own witness to the examination if required. AflexHose will provide a full Non Conformance Report for the customer.If faulty materials or a manufacturing defect in the hose was responsible for thefailure to perform then, the maximum liability to be accepted by Aflex Hose wouldinclude the invoice value of the failed hose itself, or the invoice value of the wholecustomer order if appropriate, also any reasonable costs for removal andreplacement of the hose, and costs for packing and despatching the failed hoseback to Aflex Hose. Aflex Hose USA, LLC will not accept liability for any otherconsequential or financial losses, including, but not limited to loss of profits, lossof products or downtime costs.Untested Hose for Self Assembly by CustomersAflex Hose sometimes supplies “loose” hose, without end fittings attached toSelf Assembly Customers, who will then cut the hose to length and attach endfittings to make up Hose Assemblies.Self Assembly Customers must then accept the responsibility to carry outpressure testing of 100% of such assemblies to 1 1 /2 times the Maximum WorkingPressure (MWP) if the hose as listed in the Full Product Brochure before supplyfor end use, to validate both the hose and the end fitting attachment.When pressure testing hoses with a plastic or rubber outer cover, the cover willmask any signs of leakage for a time. It is therefore recommended that after theHydrostatic Pressure Test, the hose should be tested at the MWP with air underwater for a minimum test period of 5 minutes.Unless the customer requests, and Aflex Hose confirm that their loose hose ispressure tested before supply, such testing is not normally applied by AflexHose, because this testing requirement is satisfied by the Self AssemblyCustomer during his own testing of the finished Hose Assembly.The Self Assembly Customer must also accept responsibility for determining andapproving the Design Suitability of the hose assemblies for their intended usebefore supply.This includes determining and requesting or applying any special tests whichmay be identified as necessary to ensure suitability for the intended use.Aflex Hose will only accept liability for its hose products which are assembled byAflex Approved Self-Assembly Companies if all the hose and fitting componentswere supplied by Aflex Hose or approved for use by Aflex Hose, and they wereassembled and tested in accordance with Aflex Hose’s current Manufacturingand Testing Instructions, available to approved Self Assemblers in an I-Bay onthe Aflex Hose website.Untested Hose AssembliesAflex Hose is sometimes requested by customers to attach non-standard endfittings to hose assemblies which they supply, and in some cases it is notpossible to connect these fittings to the pressure test system. In such cases aConcession not to test is obtained from the Customer, and a label is attached tothe hose assembly, warning that it requires pressure testing before use.Force MajeureAflex Hose USA, LLC shall not be liable for any delay or default in performing inaccordance with any Customers’ order if the delay or default is caused byconditions beyond its control, including, but not limited to wars, insurrections,strikes, natural disasters or performance failures by Carriers, sub-contractors orother third parties outside the control of Aflex Hose USA, LLC.Legal SystemThis agreement and any sales thereunder shall be governed by the laws of theCommonwealth of Pennsylvania, without regard to conflicts of laws rules.Page 40
