Product Description

Stainless Steel Bellows Expansion Joint Customized PTFE Expansion Joint

Products Description

The single unrestrained metal expansion joint comes with one bellows section and end connections.It can be equipped with all kinds of connectors, such as pipe weld ends or flanges. This expansion joint is mainly intended to absorb movements of axial expansion, both thermal and mechanical. In addition, to a lesser extent, it can absorb angular and lateral movements. It does not restrain pressure thrust so adequate anchors and guides must be provided and they can be used only in piping systems that incorporate correctly designed anchors and pipe alignment guides.
