They consist of aflexible bellows element, appropriate endfittings to match adjoining pipe fittingsand schedule. The bellows is a flexibleseal design to contain the media, absorbLimit RodBellowsFlow LinerThis limits the pressure stresses on thecorrugations cross section. The lowprofile design incorporates the correctnumber of convolutions to acheive thedesired movement of the bellows. Thesmaller outer diameter also savesvaluable space. Over 60 percentsmaller effective area of the bellowssubstantially reduces the size of theanchors, the structure to which thepipe guides are attached, and loweringthe overall cost while simplifyinginstallation.Old Technology -High CorrugationHigh corrugation (Figure B) isold technology. It must usereinforcing rings to acheive higherworking pressure over 50 psi. Theextreme height and pitch of theconvolutions cause the expansionjoint to have very little hoop strength,requiring external structure such asroot rings or reinforcing rings forpressures greater than 50 spi.The increased effective area of thebellows significantly increases the overall cost of a project by creating theneed for larger anchors and structureto attach the pipe guides to.SPECIFICATIONS:Pipe SIze: 6.0”Corrugation Depth: .6”Corrugation Pitch: .63”Material Thickness: .018”Pressure Rating: 150 psiA margin of approx.4 to 1 for burst pressureBy reducing the corrugation heightand pitch, we limit the pressurestresses on the corrugation crosssection.The low profile designincorporates the correct number ofconvolutions to achieve the desiredmovement of the bellows.SPECIFICATIONS:Figure A. - Low CorrugationState-of-the art low corrugation expansion joint would have an effective area of 34.5 in 2 .Pressure thrust force = (150 psig)(34.5 in 2 .) = 5176 lbs.Pipe SIze: 6.0”Corrugation Depth: 2.5”Corrugation Pitch: 2.3”Material Thickness: .125”Pressure Rating: 50 psi**To go to higherpressures, reinforcingrings must be used.The net effect is therings form the structureand the bellows formthe seal.ReinforcingRings2.5”FEATURES:• No ring reinforcement required• Lower rod and hinge hardware costs• Over 60% smaller effective area reduces anchoring costs• Extension allowance normally eliminates precompression atinstallation site• Lighter weights reduce shipping costs andsimplify installationPitch2.3”Figure B. - High CorrugationHigh corrugation expansion joint would have an effective area of 56.7 in 2 .Pressure thrust force = (150 psig)(56.7 in 2 .) = 8505 lbs.Equalizing RingEnd EqualizingRing.125”6.0”6.0”thermal movement, and pressures ofthe system.The bellows are manufactured fromthin-walled tubing to form a corrugatedcylinder. The corrugations are commonlyreferred to as convolutions and add thestructure necessary for the bellows materialto contain system pressure.The bellows design incorporates thethickness and convolution geometry thatmeets the capacity of the adjoining pipe tocontain system pressure at the specifieddesign temperature.Flexibility of the bellows is acheivedthrough the convolution profile andpitch as multiple convolutions arerequired to provide the expectedexpansion and contraction of thepiping system.AccessoriesCoversExpansion joints require careful handlingand must be protected from any impact,weld spatter, etc. Before insulating anexpansion joint, care must be taken thatforeign material is not trapped in thecorrugations impeding its movements.It is suitable to install a metal cover overthe flanges and then wrap the insulationaround it.Flow LinersFlow liners are installed in the inlet bore ofthe expansion joint to protect the bellowsfrom erosion damage due to abrasive mediaor resonant vibration caused by turbulentflow or excessive velocities.Tie RodsTie Rods are devices with the primaryfunction to restrain the bellows pressurethrust. It should be pointed out that whentie rods are furnished on expansion jointssubject to external axial movement, theywill only restrain the pressure thrust in theevent of an anchor failure. During normaloperation the anchor or adjacentequipment will be subjected to thepressure thrust forces.Limit RodsLimit Rods are devices with the primaryfunction of restricting the bellows movementrange.

Bellows Technology1.877.METAL EJ • www.flexhose.comExpansion Joint Movement CapabilitiesExpansion Joint Design ConsiderationsInstallationMisalignmentMisalignment of the expansion jointWe have noted how placing a flexible metal bellows at selected locations in a piping system can accommodate its thermal growth. There aresome side effects which occur when a pipe is cut in two and a bellows is inserted to take up the movement of the pipe. The side effects arepressure thrust or spring rate. It is essential for proper anchor designs to determine which one will impact your design.on installation reduces the totalAXIAL EXTENSIONExtension of the bellows lengthdue to pipe contraction when pipingsystem is anchored properly.AXIAL COMPRESSIONCompression of the bellows lengthdue to pipe expansion whenpiping system is anchored properly.LATERAL OFFSETMotion which is perpendicular to theplane of the pipe with the expansionjoint fittings remaining parallel.ANGULAR ROTATIONBending about the longitudinal centerlineof the expansion joint.movement capacity of an expansionjoint. Misalignment of the pipingsystem should be corrected prior toinstallation of the expansion joint.If the misalignment can not becorrected, please contactFlex-Hose Co. for technical support.Concurrent MovementsExpansion joint movement capacitypublished in the catalog is maximumcapacity for non-current movement.Axial, lateral, and angular movementscan occur simultaneously, i.e. on reactorvessels or piping systems utilizingexpansion joints at building/seismicinterfaces. If your application involvesconcurrent motions it is essential thatthe movement capacity of theSpring RateIn very low pressure application the moresignificant force may be the spring rate(force to compress the bellows) which isexpressed in pounds per inch of motion.Thus, as the pipe grows due to increasingtemperature, the bellows will resistcompression by the force noted in thespring rate (Figure A).A comparison of pressure and force datato spring rate will show that it does notrequire very much line pressure forpressure thrust to be the dominant factorof the two in expansion jointapplications.1”Pressure ThrustThe bellow’s very nature of being flexible(to absorb movement) will extend(straighten out) due to the line pressure(Figure B). This pressure thrust must thenbe absorbed by some means or the linepressure will cause the bellows to overextend and tear itself apart. This forcemay be accommodated by anchoring thepipe or by using an expanion joint whichincorporates tie rods or limit rods.SquirmConvolutions can be added to increasemovement without sacrificing cycle life,Figure B.

Change to anyof these factors will change cycle life.Directional AnchorA dierctional anchor, or sliding anchor, isone which is designed to absorb loads inone direction while permitting motion inanother. It may be either a main orintermediate anchor, depending upon theapplication considered. When designing adirectional anchor, an effort should bemade to minimize the friction between itsmoving or sliding parts, since this willreduce the loading on the pipe andequipment, and will ensure proper functionof the anchor.and must be protected from any impact,weld spatter, etc. Before insulating anexpansion joint, care must be taken thatforeign material is not trapped in thecorrugations. It is suitable to install ametal cover over the flanges and thenwrap the insulation around it.Flow LinerInstalled in the inlet bore of theexpansion joint to protect the bellowsfrom erosion damage due to abrasivemedia or resonant vibration due toturbulent flow or excessive velocities.Intermediate AnchorAm intermediate anchor is one whichdivides a pipeline into individual expandingpipe sections containing multiple expansiondevices of the same pipe size. Such ananchor must be designed to withstand theforces and moments imposed upon it byeach of the pipe sections to which it isattached. In the case of a pipe sectioncontaining one or more bellows units,these forces will consist of forces and/ormoments required to deflect the bellowsunit plus the frictional forces due to thepipe moving over its guides. The pressurethrust is absorbed by the other anchors ordevices on the bellows unit such as limitrods, tie rods, hinged restraints, etc.plane of the pipe with the expansion jointfittings remaining parallel.Limit RodDevices with the primary function ofrestricting the bellows movement range. Thelimit rods are designed to prevent bellowsover-extension or over-compression whilerestraining the full pressure thrust in theevent of a main anchor failure.Main AnchorA main anchor is one installed at any ofthe following locations in a pipe systemcontaining one or more bellows:1) At a change in direction of flow2) Between two bellows units of differentsize installed in the same straight run3) At the entrance of a side branch ontothe main line4) Where a shut-off or pressure-reducingvalve is installed in a pipe runbetween two bellows units5) At a capped end of pipeA main anchor must be designed towithstand the forces and moments imposedupon it by each of the pipe sections towhich it is attached. In the case of a pipesection containing an unrestrained bellows,these will consist of the pressure thrust,the force required to deflect the bellowsunit, and the frictional force due to thepipe moving over its guides.fastened to some rigid part of theinstallation which permits the pipeline tomove freely in only one direction, i.e.along the axis of the pipe. Pipe alignmentguides are designed primarily for use inapplications involving axial movement only.Pipe SupportA pipe support is any device whichpermits free movement of the pipingand carries the total weight of in lineequipment such as valves, meters,expansion joints, and the weight of thecontained fluid. Pipe supports cannot besubstituted for pipe alignment guides.Pipe rings, U-bolts, roller supports, andspring hangers are some examples ofconventional pipe supports.Planar GuideA directional pipe planar guide is a pipealignment guide modified to permit limitedmovement and/or bending of the pipe inone plane. It is used only in applicationsinvolving lateral deflection or angularrotation resulting from 2- or 3-hinge pipingconfigurations.Pressure ThrustExtension of the bellows due to linepressure. This pressure thrust must thenbe absorbed by some means or the lineSpring RateIn very low pressure application the moresignificant force may be the spring ratewhich is expressed in pounds per inch ofmotion. Thus, as the pipe grows due toincreasing temperature, the bellows willresist compression by the force noted inthe spring rate.SquirmStrut instability caused by internalpressure on the bellows.Thermal MovementExpansion and contraction due totemperature changes. In a piping or ductingsystem, these thermal changes can producestress on the system at fixed points such asvessels and rotaing equipment as well asthe piping or duct work system itself.Tie RodDevices with the primary function torestrain the bellows pressure thrust.TorsionTwisting about the longitudinal axis of ametal expansion joint when it is located atany point in a piping system that wouldimpose torque as a result of thermal changeor building seismic joints imposing torque.12 13

Guideline Pipe/Tube Alignment Guides1.877.METAL EJ • www.flexhose.com30Guideline GUIDELINE pipe alignment guides are designed tomaintain the longintudinal position of the pipe’scenterline with minimal axial restraints. Proper pipeguiding is vital for safe operation of piping systemsincorporating the use of expansion joints or use ofmechanical hard pipe loops. The use of traditional pipesupports (rollers, clevis hangers or U-bolts) do notassure the pipe is guided axially. Guideline assuressafety of your expansion joint system. Sizing isdetermined by the pipe size, axial movement and theamount of pipe insulation to be used. Copper tubeguides are supplied with dielectric spacers to preventgalvanic corrosion. The two piece inside spider and twopiece guiding sleeve of the Guideline provide easy bolton installation.Standard Sizes1⁄2” to 24” I.D.EXCEEDSFLEX-HOSEPRODUCT REPLACEMENT WARRANTYW A R R A N T YINDUSTRYSTANDARDSRNOTE: The recommendations givenfor pipe anchors and guidesrepresent the minimum requirementsfor controlling pipelines whichcontain expansion joints and areintended to protect the expansionjoint and pipe system from abuseand failure. However, additional pipesupports are often required betweenthe pipe guides in accordance withaccepted piping practices.A pipe support is any device whichpermits free movement of the pipingand carries the total weight of in lineequipment such as valves, meters,expansion joints, and the weight ofthe contained fluid.
