Expansion Joint SF-1200
Product Name : Expansion Joint SF-1200
Product Description
  1. The expansion joint consists of three bellows which are connected each other by flanges and limiting rods in a cross way.  The specific feature is the absorption of piping pressure while expansion and contraction action in axial movement.
  2. A pressure balanced expansion joint is a combination of single joints which oppose each other so that the internal linear pressure load of one balances that of the other through bellows.
  3. This balanced structure design prevents excessive loading due to pressure thrust, from being transmitted to pipe anchors, turbines or process equipment.  Therefore,the product is suitable for isolating vibration source, absorbing axial light oscillation, and reducing noise.  

FLANGE TYPE : JIS、ANSI、BS、DIN
