Stainless steel flexible metal expansion bellows Expansion joint bellow compensator DN25-DN600

The 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.

The effective expansion and contraction of the bellows of its working body can absorb the dimensional changes caused by thermal expansion and contraction of pipelines, conduits, containers, etc., or to compensate for the axial, lateral and angular displacement of pipelines, conduits, and containers. It can also be used to reduce noise and vibration.

It is widely used in modern industry. In terms of heating, in order to prevent the pipe from being deformed or damaged due to thermal elongation or temperature stress when the heating pipe is heating up, a compensator must be installed on the pipe to compensate for the thermal elongation of the pipe, thereby reducing the stress on the pipe wall And the force acting on the valve or support structure.
