Product Introduction of Flange Bellows Compensator:

The flange bellows compensator is a type of compensator that is distinguished based on the type of connection end. There are usually two types of compensators: butt welding and flange connection. They are both single bellows compensators composed of a group of several corrugations or complex bellows compensators composed of two groups of several corrugations. They are a type of pipe fitting that uses the elasticity and tension of the metal bellows itself to achieve deformation. They are mainly used in various pipeline systems that require valve installation or pipeline systems with large deformation. Because all pipeline connections after the valve are in a straight and rigid environment, when the pipeline undergoes thermal expansion and contraction or other weather factors deformation, if the bellows compensator is not installed, the pipeline system is likely to be affected. Due to steel deformation causing fracture or pipeline bending, This can cause danger, so when a bellows compensator is installed on the pipeline, all deformations in the pipeline system will be transmitted to the bellows expansion joint, thereby offsetting the deformation force.

Product advantages: The flange bellows compensator is mainly used on large-diameter pipelines. There may be two reasons for choosing flange connection. On the one hand, the on-site environment is harsh and welding is not allowed. On the other hand, it is for the convenience of future maintenance. When there are quality problems with the bellows compensator during use and it needs to be repaired, the compensator can be disassembled and repaired by simply removing the bolts, which is very convenient.

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.
