PTFE and PTFE lined Products
Rubber expansion joints have good features to absorb vibration and protect the valve and the whole pipeline, but most rubber materials, except Viton rubber, cannot be used for pipeline of temperature which is higher than 100℃, and cannot resist strong acid, alkali service. PTFE lining can make up the upper shortages. PTFE expansion joints can only be used for lower pressure, rubber expansion joints can be used for middle pressure pipeline, so PTFE lined rubber expansion joints is a better choice when the service is the strong acid or alkali, higher temperature and middle pressure.
