The specific method for installing a bellows compensator
Release time:
Jun 16,2022
A bellows compensator is a type of compensation device that uses the flexible deformation of its elastic element to absorb standard changes in pipelines, conduits, or vessels caused by thermal expansion and contraction. It is classified as a compensating component. The compensator can absorb axial, lateral, and angular displacements. An axial-type bellows compensator consists of a bellows tube and two end fittings; it absorbs radial displacement in the pipeline through the flexible deformation of the bellows tube.

It is classified as a compensating component. It can absorb axial, lateral, and angular displacements. An axial bellows compensator consists of a bellows tube and two end fittings; it absorbs radial displacement in the pipeline through the flexible deformation of the bellows tube.
The two ends received in between are connected to pipelines, and the fixed studs serve as rigid supports to ensure the bellows remain stable during transportation. Axial internal-pressure bellows compensators are primarily used to compensate for radial displacement; they can also accommodate lateral displacement or combined axial and lateral displacements. They have the capability to compensate for angular displacement as well, though they are generally not used for this purpose.
When using this device, please pay attention to the following points: Before installing the compensator, first check its type, standards, and pipeline configuration to ensure they comply with the design specifications. For compensators equipped with an inner sleeve, make sure the orientation of the inner sleeve aligns with the direction of medium flow. For hinged compensators, the hinge’s rotation plane must coincide with the displacement plane.
For compensators requiring “cold tightening,” the auxiliary components used for pre-deformation may only be removed after the pipeline installation is complete. 4. It is strictly prohibited to use deformation of bellows compensators to adjust installation deviations in pipelines, as this could impair the compensator’s normal function, shorten its service life, and increase the loads on the piping system, equipment, and supporting structures.
