Stainless Steel Metal Bellows Compensator Pipe Expansion Joint

Axial internal pressure type corrugated compensator, or axial internally pressurized expansion joint is a kind of corrugated compensator. It is an equipment to compensate dimensional change caused by thermal expansion or mechanical vibration of pipeline/conduit/vessel through corrugated compensator's elastic component. Based on above, it can decrease the deforming stress on pipeline and increase service life of pipeline.

Structural material: The corrugated compensator can be made of metal and nonmetal. Usually, the material of metal one include austenitic stainless steel, corrosion resistant alloy & etc. while nonmetal one include PTFE, rubber and composite material.

Wall thickness: Refer to the wall thickness, there are thick-wall corrugated compensator and thin-wall corrugated compensator. The thick one is mostly used for pressure vessel to compensate vessel's own thermal deformation. In view of its little compensation dosage, only 1~2 waves needed with wall thickness in 3~22mm generally. For the thin one, corrugated compensator is used in the flexible part of pipeline. Its monolayer thickness is less than 3mm(The thickness of most stainless steel is 0.2~3mm). Since corrugated compensator used in pipeline requires compensation dosage as much as possible, wall thickness should be reduced in max to get higher flexibility under premise of satisfying pressure-bearing. Considering environmental corrosion, most corrugated compensator are made of stainless steel. If higher pressure-bearing is requested, thin wall multilayer stainless steel structure could be better.
