Introduction to Fluorine lined Bellows Compensator Products:

Fluorine lined corrugated pipe compensator is a type of pipe fitting that uses the elasticity and tension of metal corrugated pipes to achieve deformation by lining a layer of PTFE or other materials on the inner wall of the original stainless steel corrugated pipe, in order to prevent corrosion. It is mainly used in various pipeline systems that require valve installation or have large deformations. Because all pipeline connections are in a straight and rigid environment after the valve is installed, when the pipeline undergoes thermal expansion, contraction or deformation due to other weather factors, if the corrugated pipe compensator is not installed, the pipeline system is likely to break or bend due to steel deformation, causing danger. Therefore, after installing the corrugated pipe compensator on the pipeline, all pipeline connections in the pipeline system are in a straight and rigid environment. The deformation will be transmitted to the bellows expansion joint, Thus offsetting the deformation force.

Product advantages: Fluorine lined bellows compensators are rarely used in compound compensators. They are usually lined with a layer of polytetrafluoroethylene on the inner wall of the original single type compensator's bellows. Fluorine lined bellows compensators are mainly used in highly corrosive sulfuric acid, strong alkali, and high sulfur fields. They are not only more corrosion-resistant than stainless steel bellows compensators, but also have lower cost than them..

Structural characteristics: The single-layer thickness of the corrugated pipe is usually ≤ 2 millimeters, and the fluorine lining thickness is between 1 millimeter and 3 millimeters. The single-layer thickness of the corrugated pipe can be selected according to the pipeline pressure and customer requirements. Many customers choose a double-layer corrugated pipe structure compensator for better anti-corrosion and high wear resistance of the corrugated pipe. Currently, it is widely used in steel plants and power plants.
