PTFE lined rubber expansion joint

A PTFE Lined Rubber Joint is crafted by adding a layer of polytetrafluoroethylene (PTFE) coating to the inner layer of an ordinary Rubber Joint or an ethylene propylene diene monomer (EPDM) rubber joint. This design protects the rubber joint, ensuring that its physical and mechanical properties remain unaffected even when exposed to the erosive action of strong acids and alkalis in water. Owing to this exceptional performance, many customers in the chemical pipeline industry opt for PTFE-lined Rubber Joints.

With the increasing application of PTFE-lined Rubber Expansion Joints in chemical pipelines, extending their service life has become a significant concern. Firstly, the selection of PTFE-lined rubber joints is directly related to their service life. Different types and lengths of PTFE-lined rubber joints have varying service dimensions and loads, which consequently affect their service life. It is crucial to avoid mixing different sizes during installation. Moreover, the load-bearing capacity plays a vital role; the greater the load, the shorter the service life, especially under overload conditions. Additionally, temperature is another critical factor; excessive heat can accelerate the wear and tear of PTFE-lined rubber joints. Furthermore, prolonged use on gravel roads or under harsh operating conditions will inevitably reduce the service life of these joints.

Therefore, by avoiding these situations and implementing proper maintenance for PTFE-lined rubber joints, their utilization rate can be improved, and their service life can be extended.
