Overview

PTFE provides added resistance to aggressive chemicals and temperatures versus a traditional rubber tube expansion joints.They provide an option for lower sound transmitting and dampening compared to metallic expansion joints, as well as reduce the chance of electrolysis when mating dissimilar metals.Expansion joints shall be a rubber spool type of a single, open wide arch design. Joint construction shall consist of a EPDM tube and cover with an integral PTFE liner. Joints shall be designed to meet the design pressures and temperature for the system .
Expansion joints ends shall be flanges drilled to 150# class standards, and be full rubber faced and integral to the body. Split flange backing rings of galvanized carbon steel shall be provided.
Expansion joints shall be capable of accommodating piping system and equipment movements and vibration as needed .
Control units with tie rods of galvanized carbon steel shall be included to prevent overextension of the expansion joints from pressure thrust loads . The number and size of the control rods shall be sufficient for the maximum system test pressure.

Note: 1. Special requirements can be made according to user drawings. The sphere can be made of nitrile rubber, EPDM, chloroprene rubber and other materials. 2. For suspended water supply, use products above DN200. The pipeline must have a fixed support or fixed bracket, otherwise the product should be installed with an anti-pull-off device. 3. If the user uses a rubber joint, the corresponding flange should be a valve flange.
