Product Name : SF-380 Universal Expansion Joint / Isolation Layer Type Expansion Joint
Product Description
  1. The expansion joint consists of a single bellow and a pair of hinges which is attached by flanges as ends, and a pair of pins as the axis absorbs angular rotation in the specific plane only while expansion and contraction action.
  2. This rotated structure designed to prevent the pipe distortion due to excessive heating expansion.  Also, it is very suitable for eliminating angular movement in a piping system from the earthquake.
  3. These joints are often used in sets of two or three in order to absorb pipe movement in one or more directions.  A hinge joint permits larger lateral movements to be absorbed with minimal anchor forces in a single plane piping system.

FLANGE TYPE : JIS、ANSI、BS、DIN
