Bellows Type Metal Expansion Joint SS316 High Temperature Resistance Bellows Expansion
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.
