STEAM HOSE SAFETY GUIDE(Reprinted from RMA IP-11-1 Steam Hose)Handling steam is a very hazardous situation. Using care and somesafety precaution can minimise or eliminate personal or propertydamage.SELECTING AND USING STEAM HOSE1. Make sure steam hose is identified as a steam hose. It should bebranded as such, stating working pressure and temperature rating2. Make sure working pressure and temperature is not exceeded.3. Do not allow hose to remain under pressure when not in use.4. Avoid excess bending or flexing of hose near the coupling. Straightline operation is preferred. If bends are necessary as part ofoperation, spring guards may help.5. Be sure and use recommended steam hose couplings and clamps onhose.MAINTENANCE OF STEAM HOSE1. Periodic inspection of hose should include looking for cover blistersand lumps.2. Check for kinked areas that could damage hose.3. Drain hose after each use to avoid tube damage before hose is putback in operation, to avoid “popcorning” of the tube.4. Check tightness of clamps bolts after each use.5. Check to see if clamps halves are touching. If they are, recouple hosewith smaller clamps to insure proper tightness or grip around hose.6. Do not store hose over hooks.7. Steam hose lying on metal racks or installed around steel piping willdry out the hose, causing tube and cover cracking.8. For service in sub-zero application, use only T-331 chlorobuthyl hose.The chart represents the three forms of water when subjected toheat and pressure. Use only hoses specifically designed for theapplication.Temperature °FGauge Pressure(psi)450400350300250Temperature ofSaturated Steam (°F)10 23925 26750 29875 320100 338125 353150 366175 377200 388225 397250 406TEMPERATURE OF SATURATED STEAMGauge PressureTemperaturepsi bar °C °F25 1.73 130 26730 2.07 134 27435 2.42 138 28140 2.76 141 28745 3.11 144 29250 3.45 148 29860 4.14 153 30770 4.83 158 31680 5.52 162 32490 6.21 166 330100 6.90 170 338120 8.28 177 350140 9.66 182 361160 11.04 188 371180 12.42 193 379200 13.80 198 388225 15.53 203 397250 17.25 208 406275 18.98 212 414300 20.70 216 422325 22.43 221 429350 24.15 225 437CORROSIVE STEAMWhen the water used to generate steam contains dissolved air,oxygen or carbon dioxide, then these gases end up as contaminantsin the steam. At high temperatures of steam both oxygen and carbondioxide are extremely corrosive.Carbon dioxide is acidic and therefore attacks metals whereas theoxygen corrodes metals and oxidises rubbers. Corrosion of metalsin the presence of both oxygen and acids is forty times faster thanwith either alone. Boiler water is thereforenormally treated not only toremove the “hardness” which would cause “furring” of the boiler butalso to remove dissolved oxygen and carbon dioxide and to ensurethat the steam is not only not acidic but even slightly alkaline. Boilerwater treatment is a specialised subject beyond the scope of thistechnical sheet but correct steam generation is important.DETERIORATION OF STEAM HOSELike all rubber products steam hoses have a finite life and are subjectto gradual deterioration with use. However, it sometimes happensthat hoses which have been giving a good life suddenly start failingwithout apparent reason. In such cases it is often a change in thesteam conditions causing a rapid acceleration of a normal failuremode. It is therefore useful to consider how steam hoses normally lastand thus how the condition of the steam affects hose life.HOT WATER & STEAM2001050100150200Gauge Pressure psi250Hot waterSuperheatedsteamSaturatedsteamwww.alfagomma.com 49

CHOICE, STORAGE, USE & MAINTENANCE(Reprinted from Assogomma “Recommendation regarding choice, storing, use andmaintenance of rubber hoses” June 2004.)1. CHOICE CRITERIAIn order to choose a hose suitable for a specific use it is necessary todetermine at least the following basic points:1.1 Pressure - suctionIt is necessary to determine the maximum working pressure or suctionvalues. It should be taken into consideration that the normal life of thehose will be prejudiced in the case of a sudden pressure variation orpressure peaks exceeding the maximum allowed.1.2 Compatibility of conveyed substancesThe nature, designation, concentration, temperature and state ( liquid,solid, gaseous) must be determined. In the case of solid substancesconveyed, it is necessary to indicate granulometry, density, quantityof the solid substance conveyed as well as the nature, speed and flowof the fluid carrying it.1.3 EnvironmentIt is necessary to know the place of usage, ambient temperature,hygrometric conditions and exposure to atmospheric agents. Specificenvironment conditions such as ultraviolet rays, ozone, sea water,chemical agents and other aggressive elements could cause earlydegeneration of the hose.1.4 Mechanical stressThe minimum bend radius* must be established as well as any stressrelated to traction, torsion, bending, vibration, compression, deflectionand longitudinal or transversal loads.1.5 Cover abrasionEven though the hoses are manufactured to guarantee good resistanceto abrasion, it is advisable to use further protection when damage tothe hose may be caused by shock, corrosion and/or dragging.1.6 Working positionIndicate if the hose is either placed on the ground, suspended orimmersed.1.7 Used or foreseen couplingsThis must be selected according to:- couplings and flanges: type, dimension, type of thread, standard referencesand kind of application;- hose shank: internal and external diameter and length;- ferrules/clumps: type and dimension.In order to guarantee good performance the compatibility betweenthe hose and type of coupling must be ensured. The assembly mustguarantee the working pressure suggested by the manufacturer.1.8 Technical standardsNational, European and International technical standards and rulesmust always be adhered to. In the case of hoses for peculiar purposesit is advisable to establish proper specification with the manufacturer.1.9 MarkingManufacturers must mark hoses at regular intervals with theinformation necessary for the proper use of the product.When interpretation is not clear or information is insufficient, usershould apply to the manufacturer.2. RECOMMENDATION FOR CORRECT STORAGERubber is subject, by nature, to changes in physical properties. Thesechanges, which normally occur over the course of time, according tothe kind of rubber used, can be accelerated by one particular factoror by a combination of these.Reinforcement materials are also adversely affected by unsuitableconditions of storage. The following recommendations give someprecautions to be taken to ensure the minimum deterioration to storedarticles.2.1 Storage lifeStorage time should be reduced to the minimum through programmerotation.When it is not possible to avoid long term storage, it is necessary thatthe user, as indicated in ISO 8331, carries out a complete check of thehose before its use according to the following criteria:- maximum two years storage for assembly;- maximum four years storage for hoses.2.2 Temperature and humidityThe best temperature for the storage of rubber hoses varies from 10to 25 degrees centigrade. Hoses should not be stored at temperatureabove 40 °C or below 0 °C. When the temperature is below –15 °C itis necessary to take precautions when handling.Hoses should not be stored near sources of heat nor in conditionsof high or low humidity. A humidity level of a maximum of 65% isrecommended.2.3 LightHoses must be stored in dark places, avoiding direct sun light or strongartificial light. Should store rooms have windows or glass openings,these must be screened.2.4 Oxygen and ozoneHoses should be protected from circulating air by suitable packingor by storage in air-tight containers. As ozone has a particularlyaggressive action on all rubber products, the store house must notcontain material producing ozone like devices under high electricaltension, electric engines or other materials provoking sparks orelectric arcs.2.5 Contact with other materialsHoses should not come into contact with solvents, fuels, oils, greases,volatile chemical mixtures, acids, disinfectants and other organicliquids in general.Furthermore direct contact with some metals ( for example manganese,iron, copper and its alloys) and relative mixture exercise harmfuleffects on some types of rubber.Contact with PVC and creosote impregnated timber or fabrics shouldbe avoided.2.6 Heat sourcesThe temperature limits given in point 2.2 must be respected. Whenthis is impossible, it is necessary to use a thermic shield at a distancenot less than one meter.2.7 Electric or magnetic fieldVariation in electric or magnetic fields must be eliminated in storehouses as these could provoke currents in metal coupling, heatingthem. Similar fields could be caused by high-tension cables or highfrequency generators.* The minimum bend radius is the radius to which the hose can be bent in service without damage or appreciably shortening its life. The radius is measured to the inside of thecurvature. Formula to determine minimum hose length given bend radius and degree of bend required:L =A360°x 2 π BWhere:L = Minimum length of hose to make bend (Bend must be made equally along this portion of hose length).A = Angle of bendB = Given bend radius of hoseπ = 3.14Example: To make a 60° bend at the hose’s rated minimum bend radius of 15 cmL =60360°x 2 x 3.14 x 15 = 15.7 cm ~ = 16 cmThus, the bend must be made over approximately 16 cm of hose length. The bend radius used must be equal to or greater than the rated minimum bend radius.Bending the hose to a smaller bend radius than minimum may kink the hose and result in damage and early failure.www.alfagomma.com 119

CHOICE, STORAGE, USE & MAINTENANCE2.8 Storage conditionsHoses must be stored in a relaxed condition free from tension,compression or other deformation and contact with objects thatcould pierce or cut must be avoided. It is preferable to store hoses onspecial shelves or on dry surfaces.Coiled hoses must be stored horizontally avoiding piling. When this isnot possible the height of the piles must be such to avoid permanentdeformation of hoses stored underneath.The inside diameter of the coil, during the storage, must be such asto not compromise the performances of the products. In particular,this diameter must not have value less than those indicated by themanufacturers.It is advisable to avoid storing coiled hoses on poles or hooks.Furthermore it is advisable to store hoses to be delivered straight,horizontally, without bending.2.9 Rodents and insectsHoses must be protected from rodents and insects. When such a riskis probable adeguate precautions must be taken.2.10 Marking or packaged itemsIt is advisable that hoses are always easy to identify even ifpackaged.2.11 Exit from storagePrior to delivery hoses must be checked for integrity and mustcorrespond to the required use. After long storage if couplings arenot clipped, swaged or built-in, it is necessary to check that lockingcollars are tight.2.12 Return to storageHoses that have been used must be free from all substances prior tostorage. Particular attention must be paid when chemical, explosive,inflammable, abrasive and corrosive substances have been conveyed.After cleaning, check whether the hose is suitable to use again.3. NORMS AND METHOD OF USEAfter having chosen the type of hose, the users must keep in mind thefollowing hose installation criteria:3.1 Preassembly checksPrior to installation it is necessary to check the characteristics of thehose carefully to verify that type, diameter and length conform withthe required specifications. Moreover a visual check must be effectedto make sure that there are no obstructions, cuts, damaged cover orany other evident imperfections.3.2 HandlingHoses must be moved with care avoiding knocks, dragging overabrasive surfaces and compression. Hoses must not be pulledviolently when twisted or knotted. Heavy hoses, normally deliveredin a straight line, must be laid on special supports for transport (seeattachment). Should wood supports be used these must not be treatedwith creosote or painted with substances which could damage therubber.3.3 Pressure and seal testThe working pressure generally indicated by manufacturer mustbe respected. Following installation, when air bubbles have beeneliminated, increase the pressure to test the assembly and checkpossible leaks. This test must be carried out in a place free fromdanger.3.4 TemperatureHoses must always be used within the temperature limits generallyindicated. In case of doubt apply to manufacturers.3.5 Conveyed productsHoses must be used exclusively to convey substances for which theywere manufactured. In case of doubt it is always advisable to contactmanufacturer. As far as possible, hoses must be empty after usage.Where any risks are involved special precautions must be taken toavoid bursts.3.6 EnvironmentHoses must be used exclusively in the environment conditions forwhich they were manufactured.3.7 Bending radiusInstallation underneath the minimum bending radius reduces the lifeof the hose considerably. Morover it is necessary to avoid bending atfitting ends. *(See attached 1).3.8 TorsionHoses are not manufactured to work in torsion, except for specificpurposes.3.9 TractionTraction must be within limits specified by manufacturer. In case ofdoubts it’s advisable to get in touch with manufacturers.3.10 VibrationVibrations subject hoses to stress from heat and fatigue above all nearcouplings and premature bursting may occur. It is therefore advisableto check that hoses have been manufactured to resist such stress.3.11 KinkingSome users tend to obstruct the flow of liquids by kinking the hose. Thissystem is not advised by manufacturers because the reinforcement issubjected to eccessive stress and could lead to bursting.3.12 Choice and application of couplingsProvided that the manufacturers instructions are met it is alwaysnecessary to check the compatibility between the working pressureof couplings and hoses. Couplings with too large diameters causeabnormal stress which can split the hose reinforcement, whilst toosmall dimensions can create clumping difficulties and leakage.Furthermore couplings must be free from sharp and cutting edgeswhich could damage the hose.Water or soap and water can be used to fit couplings. Do not useproducts containing oils or solvents except for the kind of hosesdestined to be used with the latter.Softening hoses with mallet or similar tools is forbidden.Take care to avoid external collars or other tightening tools. The useof makeshift collars (for example wire) with sharp edges or too tightclumping leads to damage of cover and reinforcement.3.13 Electrical propertiesElectrical properties of hoses and assemblies, are measured betweencouplings and/or the end of the hose and are expressed in Ohm.The hoses are divided into three grade:a) continuous (M grade)they contain little ropes or wire helics.Resistance < of 102 ohmb) Conductive or antistatic (Ω grade)They contain rubber or plastic conductive sheetsResistance > 103 ohm < 10 6 ohmc) Insulating or discontinuousThey contain rubber or plastic insulating sheetsResistance > 10 6 ohm3.14 Installation between two pointsThe hoses must be supported in a suitable way, so as the normalmovement when the hose is under pressure (variations in length,diameter, twisting, etc.) are allowed.3.15 Mobile piecesWhen hoses link mobile pieces, it is necessary to check that the lengthof the hose is suitable and that the movement does not subject thehose to shock or chafing and that abnormal stress, bending, tractionor torsion do not occur.3.16 IdentificationIf further marking is necessary, self-adhesive tape may be used.When the use of paint is unavoidable check compatibility of coverwith manufacturer.4. MAINTENANCEEven though choice, storage and installation have been carried outcorrectly regular maintenance is necessary.Frequency of the latter is determined according to use involved. Duringregular check special attention must be paid to couplings and to theappearance of the following irregularities which show deterioration ofhose:• Cracks, cuts, abrasions, unsticking, tears in cover revealingreinforcement;• Deformity, bubbles, local swalling under pressure;• Sticky or soft areas;• Leaks.Such irregularities justify hose substitutions. When cover bears dateof expiry this must be kept to even if the hose shows no apparentsigns of wear.4.1 RepairsHose repairs are not advisable. However when deterioration occurseat an end section, and if the full length allows for such, the wornsection may be eliminated.4.2 CleaningIf cleaning instructions are not supplied by the manufacturer clean,if necessary, with soap and water avoiding use of solvents (petrol,paraffin, etc) or detergents. Never use abrasive, pointed or cuttingtools (wire brushes).120 www.alfagomma.com

CHEMICAL GUIDEThe chemical guide in this section is offered as a general indication of the compatibility of the various materials used in ALFAGOMMA hose with thechemicals and fluids listed. The basis for the ratings in this guide include actual service experience, the advice of various polymer suppliers, andthe considered opinion of our rubber chemists. When in doubt, a sample of the compound should always be tested with the particular chemical itis to handle. Some of the variables that come into play in the resistance of a compound to chemical attack are:1. Temperature of the Material Transmitted:Higher temperatures increase the effect of chemicals on rubber compounds. The increase varies with the polymer and the chemical. Acompound quite suitable at room temperature might fail very quickly at higher temperatures.2. Service Conditions:A rubber compound usually swells when exposed to a chemical. With a given percent of swell, a hose tube may function satisfactorily if thehose is in a static condition, but fail quickly if the hose is subject to flexing.3. The Grade or Blend of the Rubber Compound:Basic rubber polymers are sometimes mixed or blended together to enhance a particular property for a specific service. The reaction to aparticular chemical blend of polymers may, therefore, somewhat different from the reaction to the single ones. When in doubt, a sample ofthe compound should always be tested with the particular chemical it is to handle.GENERAL CHEMICAL RESISTANCE OF ALFAGOMMA HOSE COMPOUNDSCOMMON NAMEASTMDesignationD1418-93COMPOSITIONGENERAL PROPERTIESNatural rubber NR Isoprene rubberSBR SBR Styrene-butadiene rubberButyl rubber IIR Isobutene-isoprene rubberExcellent physical properties, including abrasion resistance.Not oil resistant.Good physical properties, including abrasion resistance.
