The PTFE-lined rubber expansion joints ordered by Russian customers have all been completed.

PTFE lined rubber expansion joints are designed for industrial aggressive chemical applications with an integral PTFE liner and EPDM rubber. It is used in many industrial applications, including the pulp and paper industry, where the need to resist high pressure corrosion is critical. Rated to 250F.

When the rubber expansion joint is lined with a PTFE Teflon liner, all the properties of PTFE Teflon will help the rubber expansion joint to function. Useful when transporting chemicals, acids, corrosives and other hazardous substances through pipelines.

PTFE has the following properties:

• Good thermal stability, high temperature resistance, the highest temperature resistance is 260°C, and the low temperature resistance is -200°C.
• non-stick surface
• very low coefficient of friction
• Resistant to corrosive liquids and some chemical attacks.

Industrial applications where PTFE-lined rubber bellows can be used include:

Paper mills, chemical plants, desalination plants, fertilizer plants and processing plants using chemicals or high or low temperatures.
