Product Name : Expansion Joint SF-400STG & SF-400SG
Product Description
  1. The pipe expansion joint is simply a bellows element with flanges as end connections.  Due to bellows made of stainless with convolution welding in longitudinal direction and contained internal tube and limited support rods, the trust force induced by fluid disturbance could be defended and corrective movement in axial direction is held.
  2. The products are suitable for a working room to absorb axial movement excited by thermal expansion or contraction of piping systems and equipment.
  3. Bellows are made of multi-layer stainless sheet structures; therefore, they could be applied to a high pressure and heat medium (refrigerant) piping system where the high temperature fluid generates thermal expansion.

FLANGE TYPE : JIS、ANSI、BS、DIN
