Product Description

The welded metal expansion joints of a corrugated pipe, two end pipes, and other components. It absorbs axial displacement of the pipeline (with small amounts of lateral and angular displacement) through the flexible deformation of the corrugated pipe, and the end pipe is either directly welded to the pipeline or connected to the pipeline flange after welding. The small pull rod on the expansion joint is mainly used as a rigid support during transportation or as a pre deformation adjustment for products, and it is not a load-bearing rod.

NO	Name	Material
1	Shipping Rod	SS304,ss306,carbon steel,etc
2	Bellow	Stainless steel
3	Welded pipe	Stainless steel

 

 

Characteristics of welded metal expansion joints

1.Compensate for axial, transverse, and angular thermal deformation of the absorption pipeline.

2.The expansion and contraction of the bellows compensator facilitates the installation and disassembly of valve pipelines

3.Absorb equipment vibration and reduce the impact of equipment vibration on pipelines.

4.Absorb pipeline deformation caused by earthquakes and settlements.
