Metal bellows expansion joint

Metal rectangular corrugated compensator belongs to a kind of compensation element. 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, conduits, containers, etc., or to compensate for the axial, lateral and angular displacement of pipelines, conduits, containers, etc. It can also be used to reduce noise and vibration.

The corrugated pipe compensator is a perturbing element with the corrugated pipe as the core, and can be used for axial, lateral and angular compensation in the pipeline.

In order to reduce the self-excitation of the medium, the axial compensator is equipped with an inner sleeve inside the product, which limits the radial compensation ability to a large extent. Therefore, it is generally only used to absorb or compensate the axial displacement of the pipeline (if the pipe system A small amount of radial displacement is indeed required in the medium, and it can also absorb a combination of axial, angular and any three-direction displacement;

Hinge compensator (also called angular compensator), which is used in conjunction with two or three compensators (a single hinge compensator has no compensation capability) to absorb lateral deformation in a single plane; universal hinge (angular ) The compensator, which is used as a set of two or three, can absorb the amount of deformation in the three-dimensional direction.
