Stainless Steel Pump Connector/Bellow Compensator/Expansion Joint for Industrial Pipeline /Building

Metal bellows expansion joint adopts EJMA standard optimization design, axial internal pressure type ripple compensator is also commonly called shock-absorbing ripple compensator, bellows, expansion joint, or expansion joint. It is composed of a corrugated pipe (an elastic element) and an end pipe, a support, a flange, a conduit and other accessories.

The axial internal pressure type ripple compensator belongs to a compensation element. The effective expansion and deformation of the working body of the bellows is used to absorb the dimensional changes of pipelines, conduits, containers, etc. caused by thermal expansion and cold contraction, or to compensate the axial, lateral and angular displacement of pipelines, conduits, containers, etc. It can also be used to reduce noise and vibration. It is widely used in modern industry.

Axial internal pressure type ripple compensator is also called expansion device, expansion joint, ripple compensator. The compensator is divided into: corrugated compensator, sleeve compensator, rotary compensator, square natural compensator and other types, among which the corrugated compensator is more commonly used, mainly to ensure the safe operation of the pipeline, with the following functions:

1. Compensation absorption pipe axial, lateral, angular heat deformation.

2. Corrugated compensator expansion, convenient valve pipe installation and disassembly.

3. Absorb equipment vibration to reduce the impact of equipment vibration on the pipeline.

4. Absorb the deformation of the pipeline caused by earthquake and subsidence.

The expansion joint is composed of a corrugated pipe and a structure, which is mainly used to absorb axial displacement and less transverse and angular displacement, has simple structure and low cost, and is also known as a universal compensator.
