Promise The Quality, Create The Value.

  • 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.
  • These rotated structures designed to prevent the pipe distortion due to excessive heating expansion. Also, they are very suitable for eliminating angular movement in a piping system from the earthquake.
  • Universal Expansion Joints / Isolation Layer Type expansion joints consist 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.
  • Universal Expansion Joint SF-800 piping expansion joint consists of two bellows with flanges as the connection element, a middle cylinder and four external limit rods. Bellows and a cylinder are made of stainless steel via convolution welding in longitudinal direction.

Engineering Performance
We serve the project performance across the various industries, including commercial buildings, residential buildings, chemical plants, semiconductor factories, hospitals, MRT, telecommunications room, high-speed rail, tunnels, power plants and other domestic indicators of large projects


Universal Expansion Joint SF-800's specific feature is the absorption of piping lateral movement. It is suitable for the applications in building expansion (movement) joints or isolation layers in structures as piping gap compensation.
