Metal Expansion Joint

Single Expansion Joint
  • Absorbs all three types of movement
  • Deflects in any direction
  • No change in direction of flow
  • Minimum installation space and easy to install
  • The least expensive type of expansion joint
  • Strong anchors require to control pressure thrust

 Single expansion joint is the simplest form manufactured from single and multi-ply elements. It consists of bellows element with end connections. It is used for axial movement only in pipe configurations. However, it can also absorb small amounts of other two types of basic movements-lateral and angular. This type of expansion joint provides most economical solution in an installation where proper anchoring and guiding is feasible.
Unreinforced bellows or reinforced bellows and multi-ply bellows can be designed and manufactured based on the application and design requirements.
