Joint de dilatation en caoutchouc
Expansion Joints are also called compensators or Expansion Joints.
It is composed of bellows (a kind of elastic element) and end pipe, bracket, flange, conduit and other accessories.
Expansion joint is a flexible structure set on the container shell or pipe to compensate for the additional stress caused by temperature difference and mechanical vibration.
The effective expansion deformation of the bellows of the main body of the work is used to absorb the size changes of pipelines, conduits and containers caused by thermal expansion and cold contraction, or to compensate the axial, transverse and angular displacement of pipelines, conduits and containers.
Expansion joint material is divided into fabric, metal, rubber and so on.
