1 179 Edition 3 Section 12 Rubber Bellows180 [12] Rubber BELLOWSS pecificationsA Rubber bellow is a flexible joint made from heat resisting synthetic elastomers and moulded in a spherical shape with metal floating Bellows (Fleixble Rubber Joints) are installed in piping systems to absorb movements in three directions 1. Axial - the movement of elongation and compression along the centre line2. Lateral - offset movement from the centre line 3. Angular - offset bending about the centre lineApplications - Air, Compressed Air, Water, Sea Water, Hot Water, Weak Acid Material ListWorking ConditionsPARTMATERIALW orking Pressure DN32-DN3001600kPaBodyEPDM/NBRW orking Pressure DN350-4501000kPaLiningNylon cord FabricWorking Pressure DN450-DN1000600kPaFrameHard steel wireBursting kPaSummaryCODERUBBERFLANGERB**EPDMAS2129 E RB**NNBRAS2129 E RB**DEPDMAS2129 D RBA**NNBRANSI **EPDMBS4504 X AS2129 E **Denotes sizeCOMMON NAMEASTM DESIGNATION D1418-64 TEMPERATURECOMPOSITIONGENERALLY RESISTANT TOGENERALLY AFFECTED OR ATTACKED BYNitrile or Buna-N NBR-25 C + 100 CNitrile ButadieneMany Hydrocarbons, fats, oils, greases, hydraulic fluids and chemicalOzones, keytones, esters.
