Why Rubber Expansion Joints?There are a number of reasons why rubber expansion jointscan provide the ideal solution to your piping and plumbingproblems:● Minimal face-to-face dimensions — Rubber expansionjoints require considerably less space than typicalexpansion bends or loops and frequently have a lowerpressure drop. This can translate into savings oninstallation costs, as well as improved performance.● Light weight — Rubber expansion joints are relativelylight in weight. This makes installation easier and lesscostly.● Low movement forces required — The naturalflexibility of rubber expansion joints allows almostunlimited flexing and recovery, as well as requiring lessforce to move. This helps prevent damage to costlyequipment and expensive down time.● Reduced fatigue factor — The elastomers used inrubber expansion joints are not subject to fatiguebreakdown or embrittle ment. And they prevent electrolyticaction.● Reduced heat loss — Rubber expansion joints reduceheat losses and give longer maintenance-free service.● Corrosion- and erosion-resistance — The superiorcorrosion-resistant characteristics of rubber expansionjoints permit the safe handling of a wide variety ofmaterials within the rated pressures and temperaturesshown.Typical ApplicationsAir Conditioning, Heating & Ventilation SystemsCommercial & Institutional Buildings HospitalsSchoolsMotelsApartmentsHotelsStoresAboard Ships & BoatsCentral & Ancillary Power Generating StationsCommunitiesBuildingsFactoriesAboard Ships & BoatsSewage Disposal & Water Treatment PlantsIrrigation & Fire Fighting StationsProcess PipingPulp & PaperChemicalPrimary MetalPetroleum RefiningRubber Expansion Joint MovementExpansion joints are designed to absorb different movements concurrentlyAxial Compression Axial Elongation Angular DeflectionBending of the CenterlineTorsional MovementRotation about the centerline (twist)Transverse DeflectionPerpendicular to centerlineVibrationBECAUSE WE CONTINUALLY EXAMINE WAYS TO IMPROVE OUR PRODUCTS, WE RESERVE THE RIGHT TO ALTER SPECIFICATIONS WITHOUT PRIOR NOTICE.40KCCA1110
