PTFE Lined rubber expansion joints
The rubber expansion Joint with PTFE provide good corrosion-resistance and good chemical -resistance in piping system. The PTFE are lined through the entire length of the joint and covers both end flanges completely.
The PTFE liner is backed by a fabricated rubber body, the reinforced middle layer is impregnated with nylon tire cords, which can increase the flexibility and stiffness.
The outer cover is used according tot the working conditions, such as UV resistance, acid-resistance, or alkali resistance,ozone, etc.
PTFE lined expansion joints are available with single sphere, double sphere, single arch, wide arch or full-faced flange rubber joints.
PTFE Lined Expansion Joints with elastomer and fabric body are suitable for 132℃ applications.
Control units are recommended to prevent possible damage from excessive elongation or movement.
