PTFE lined expansion bellows rubber are mainly used for flexible connections between metal pipelines. Their structure includes a tubular rubber component composed of inner and outer layers of rubber, curtain layers, and steel wire rings. After vulcanization molding, it is then loosely combined with metal flanges or parallel joints. This type of joint combines the flexibility of rubber material with the excellent chemical stability of PTFE material, allowing it to maintain good sealing and durability in harsh environments such as high temperature, high pressure, and strong corrosion.
