Description
Polyurethane expansion joints are composed of flange loose sleeve expansion joints, short pipe flanges, limit screws, etc., which can reduce the pressure thrust of the connected parts and compensate for pipeline installation errors, mainly used for pumps, valves, pipelines and other accessories length error compensation.
Polyurethane expansion joints can be axially expanded and contracted within a certain range, which can greatly facilitate the installation and disassembly of valves and pipelines. When installing, adjust the connection length at both ends of the expansion joint, and evenly tighten the gland bolts diagonally once, and then adjust the limit nuts, the expansion and contraction amount can be locked to ensure the safe operation of the pipeline.
