Product description

The metal corrugated compensator is also called expansion joint or expansion joint. It is composed of bellows (a kind of elastic element) and accessories such as end pipes, brackets, flanges, and conduits that constitute the main body of the work. Belongs to a compensation component. Utilize the effective expansion and contraction of the bellows of its working body to absorb the dimensional changes caused by thermal expansion and contraction of pipelines, ducts, containers, etc., or to compensate for the axial, lateral and angular displacement of pipelines, ducts, and containers. It can also be used to reduce noise and vibration.

Features

        The expansion joint is composed of a bellows and two connecting pipes. It absorbs axial displacement (a small amount of lateral and angular displacement) through the flexible deformation of the bellows. There are two forms of connecting pipe and flange connection. The small pull rod on the expansion joint is mainly used as a rigid support during transportation or for adjusting the size when the product is pre-deformed, not a load-bearing part. This type of expansion joint cannot restrain the pressure thrust of the pipeline, and the pressure thrust is borne by the main fixed pipe racks on both sides.
