SF-680 Universal Expansion Joint / Isolation Layer Type Expansion Joint ISOLATION LAYER TYPE EXPANSION JOINT

Product Name : SF-680 Universal Expansion Joint / Isolation Layer Type Expansion Joint

The joint consists of two-hinge expansion bellows with flanges as the connection element, and a middle steel tube. Not only lateral movement could be reduced by its bellow-hinge structure obviously, and also a working place will benefit by its easy assembly.
This designed structure could prevent the piping distortion due excessive heating expansion, and could eliminate angular movement resulting in large deflection of a piping system from the earthquake.
It is possible to assemble a single joint and a set of hinge joints as an absorption device of lateral movement for a piping system in the X and Y coordination.

FLANGE TYPE : JIS、ANSI、BS、DIN
