Expansion Joint SF-1100
Product Name : Expansion Joint SF-1100
Product Description
  1. The pipe expansion joint consists of a bellow element, an external sleeve and an internal sleeve.  The specific feature is the absorption of piping pressure at the outer side of a bellow for piping axial movement.  Bellows have expansion and contraction action in axial movement with contrast to an internal expansion joint.
  2. Due to external-pressure bellow design, the expansion joint could absorb axial movement via fluid flow in axial movement; therefore, it could be widely applied to the large axial expanding momentum.
  3. The expansion joints have installed an external sleeve to protect bellows so that they are very suitable for a trouble environment and the special working space.
