DN50 - DN300 Reduced Rubber Expansion Joint Flanged Type
Reduced Rubber Expansion Joint is composed of fabric reinforced rubber body and metal flange or screw thread flexible joint, which is used for vibration reduction, noise reduction and displacement compensation of pipeline. It is also known as rubber soft joint, shock absorber, pipe shock absorber.
Introduction of Reduced Rubber Expansion Joint
An expansion joint is a specially engineered product inserted in a rigid piping system to achieve one or more of the following:
» 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
