Rubber expansion joint is also called flexible rubber joint shock-absorbing throat, flexible rubber connector, air spring pipe shock absorber, shock absorber throat, rubber soft joint, rubber pipe joint, air-conditioning pump shock absorber throat, etc.
Rubber expansion joints are the movable parts of pipeline systems, it is mainly consisting of two pcs flange and one rubber sphere body, flange is used for connection, rubber sphere body is flexible, which can absorb the axial, horizontal and annular displacement.
It is a flexible connector fabricated of natural and/or synthetic elastomers and fabric, if necessary, internal metallic reinforcements designed to provide stress relief in piping systems due to thermal movements and mechanical vibration.
Typical places for installing the rubber expansion joints are pumps, water supply pipelines, transporting lines for crude oil and petroleum, as well as for the aggressive liquid media (for instance, acids).
