Product Introduction of Small Pull Rod Bellows Compensator:

The small pull rod corrugated pipe compensator is also a type of compound corrugated pipe compensator. It is a pipe fitting that uses the elasticity and tension of the metal corrugated pipe itself to achieve deformation. It is mainly used on various pipeline systems that require valve installation or pipeline systems with large deformation. Because all pipelines connected to valves are in a straight and rigid environment, when the pipeline undergoes thermal expansion and contraction or other weather factors deformation, if the corrugated pipe compensator is not installed, the pipeline system is likely to break or bend due to steel deformation, causing danger. Therefore, when the corrugated pipe compensator is installed on the pipeline, all deformations in the pipeline system will be transmitted to the expansion joint of the corrugated pipe, thereby offsetting the deformation force.

Product advantages: The large pull rod bellows compensator is a composite type compensator, which is composed of two sets of single bellows and a set of intermediate connecting pipes. The connecting pipes of the bellows at both ends are connected to the middle connecting pipe with small pull rods. The reason why small pull rods are used to connect them is to prevent excessive deformation and damage to the compensator during installation and use. Its advantage is that it can expand and contract laterally and axially, and the expansion distance is usually greater than that of the single bellows compensator. At the same time, it also plays a role in fixing the bellows.

Structural characteristics: The single-layer thickness of corrugated pipes is usually ≤ 2 millimeters. The single-layer thickness of corrugated pipes can be selected according to pipeline pressure and customer requirements. Many customers choose double-layer corrugated pipe compensators for better anti-corrosion and high wear resistance of corrugated pipes. Currently, steel plants and power plants use them in large quantities.
