Product Description

Stainless steel flexible metal expansion bellows/ Expansion joint/ bellow compensator

Product 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.

Feature:

1. To Absorb large axial displacement between straight tube and support frame , and small horizontal displacement;

2. To resolve minor deviation because of piping connection and eliminate the pipeline residual stress;

3. Easy cleaning and maintenance.

Applications: For the chemical industry, metallurgy, electricity, shipbuilding, construction and other industries.

Application temperature:-50 ºC~300ºC.
