How many kinds of bellows compensators are there?

Bellows compensator, also called expansion joint, or corrugated compensator, is a kind of compensation device, which is used to absorb the dimensional change of pipeline, conduit or container caused by thermal expansion and cold contraction due to the effective expansion and deformation of bellows compensator and elastic element of expansion joint, and belongs to compensation element. It can absorb axial, lateral and angular displacement. It is used to reduce vibration and noise when pipelines, equipment and systems are displaced by heat and machinery. Corrugation compensator is a flexible structure installed on the container shell or pipeline to compensate the additional stress caused by temperature difference and mechanical vibration.

As a flexible compensation element, it has the advantages of reliable operation, good performance and compact structure, and is widely used in chemical industry, metallurgy, nuclear energy and other departments.

There are many forms of ripple compensators used in containers. As far as waveform is concerned, U-shaped expansion joints are the most widely used, followed by ω-shaped and C-shaped. As far as structural compensation is concerned, corrugated compensators used in pipelines are universal, pressure balanced, hinged and universal joint.

Corrugated compensators can be divided into three types: axial, transverse and angular.

Precautions for purchase: data should be provided to the manufacturer when purchasing, and the manufacturer can design and produce to ensure the service life or quality. Corrugated compensator is a special pipeline equipment. When purchasing, you should choose qualified manufacturers or well-known brands to avoid accidents. Recommended manufacturers: Hebei Ye Wei Bellows Manufacturing Co., Ltd. and Baishun Bellows Compensator, a well-known brand in China market.
