Carbon steel reduced viton FPM FKM rubber expansion joint
Reducer rubber bellows expansion joint is made up of fabric reinforced rubber main body and metal flange or wire buckle joint, which is used for vibration reduction, noise reduction and displacement compensation of pipeline. It is related to: JGD single sphere rubber joint, jgd-a double sphere, jgd-b wire buckle connection double sphere, etc., it is A high elasticity, medium resistance and weather resistance pipe joint. It is also known as rubber soft joint, shock absorber, pipe shock absorber, shock absorber throat, size head, variable-diameter joint, but the name is different, but refers to reducer rubber bellows expansion joint.
Introduction
An expansion joint is a specially engineered product inserted in a rigid piping system to achieve one or more of the following:
» Absorb movement
» Relieve system strain due to thermal change, load stress, pumping surges, wear or settling
» Reduce mechanical noise
» Compensate for misalignment
» Eliminate electrolysis between dissimilar metals
