High Grade Pipeline Metal Bellows Expansion Joint Axial Corrugated Compensator
Introduction of metal expansion joint:
Metal expansion joint also known as expansion joints.It is composed of a corrugated pipe (an elastic element), an end pipe, a bracket, a flange ,a conduit and other accessories. It mainly used in various pipelines, it can compensate the thermal displacement of the pipeline, mechanical deformation and absorption of various mechanical vibrations; Play a role in reducing deformation stress and improving the service life of the pipeline.
Application:
Extremely flexible
Extremely durable
Lasts the life of mechanical system Handles greater
Offsets without a compromise of hose integrity
Available in a variety of end fittings
