PTFE lined pipe and fittings are resistant to corrosion, full vacuum and high pressure during corrosive liquid handling. PTFE lined pipes and fittings are commonly used for highly corrosive fluid handling at high temperatures. From –50 to 230°C, from full vacuum to the highest pressure condition, allows the transportation of all corrosive chemicals.

Liwei PTFE rubber expansion joint could primarily reduce the quiver and the noise of the piping system; completely solve the different piping problems as displacement of joint, axial flex and etc.

Specifications of Liwei PTFE rubber expansion joint:
1. Body (Outer Layer & Inner Layer): EPDM NBR and Neoprene Rubber
2. Reinforcing Layer: Nylon Fabric
3. Wire: Stainless Steel Wire
4. Flange: Carbon Steel and stainless steel
5. Flange Drillings: BS, DIN, ANSI, JIS or others provided drawing samples

According to different material requirement, Liwei PTFE rubber expansion joint could be made as acid proof, alkali proof, and corrosion proof to suit different medium and environment.
The material is good sealing, light weighting, easy to fix and maintain, also has long usage life. But please keep far away from sharp metal in order to avoid breaking of the ball.
