The increased application of PTFE lined rubber joints meets the use of chemical pipelines. In the previous use of rubber joints, due to the passage of some extremely corrosive media, the flexible rubber joints often cannot withstand corrosion and cause their performance to drop sharply. Due to the defects in corrosion resistance of rubber, glass, metal alloys and other materials, it is difficult to meet the harsh conditions of temperature, pressure, and chemical media coexistence. The losses caused by this are quite amazing. PTFE materials have excellent corrosion resistance and have become the main corrosion-resistant materials in the petroleum, chemical, and textile industries.

PTFE lined rubber joints are mainly used in strong acid, strong alkali, and high temperature medium pipelines. Its characteristics are better than ordinary acid and alkali resistant rubber joints. The characteristics of PTFE: the ability to withstand negative pressure is slightly poor. Compared with single and PTFE rubber joints, the cost of PTFE lined sea rubber joints is relatively low, which is easy to be accepted by customers and can meet the needs of most customers who need strong acid and alkali resistant rubber joints.

Features of PTFE lined rubber joints: High internal density, can withstand high pressure, and good elastic deformation effect.

Advantages of PTFE lined rubber joints: Reduce vibration, reduce noise, and be lightweight.

Purpose of PTFE lined rubber joints: Connection with pumps, valves, fire fighting equipment, pipes with large vibrations, and pipes with frequent changes in temperature.
