ANSI Standards NBR Rubber Expansion Joints with Galvanized Flange Coating

Model Number: Solid-Rubber Expansion-#6899 Brand Name: SOLID Key Specifications/Special Features: Flange: steel to SABS 1431 grade 300WAFlange coating: galvanizedRubber seal: EPDM or NBRExpansion joint are low cost vibration and deflection absorption components in fluid conveyance pipelinesBellows consists of two symmetrical connecting ends, either threaded unions for smaller nominal bores or flanged ends for larger nominal bore pipelines

Body of the bellows is essentially a robust rubber cylinder that is capable of absorbing vibration and movement in pipeline components

Bellows are often installed in-line with water pumps as the absorber of the operating vibration of the pump and movements due to pump start up, shut down

Bellows are also able to absorb axial displacement due to pipeline expansion and contraction, and lateral displacement and pipeline angularity

Available range: DN 20-1000mm
