Chemical production plants are carried out under certain temperature and pressure conditions, and their skills are severe. The materials involved are various gases, liquids, and solids. The properties vary widely and various types of production equipment are required. However, these equipments that are in contact with the medium are corroded at all times in the production, and then severely restrict the development of the chemical industry and other industries. When technology is underdeveloped, we always look for preservatives in metals. However, these devices often cost a lot of money and cannot solve many corrosion doubts.
Only then did we explore the substitution of metals with non-metal resources. The first plastic used in China was polytetrafluoroethylene, followed by the introduction of fluoroplastics such as polytetrafluoroethylene, polytrifluoroethylene, polyperfluoroethylene, and thermoplastics such as polyethylene, polypropylene, and ABS.
With the advancement of science and technology, the anti-corrosion equipment made of traditional non-corrosive non-metallic materials has been gradually improved, and new types of non-corrosive non-metallic materials have been emerging. In the wave of selecting new skills and new materials for the development of new anti-corrosion products, polytetrafluoroethylene anti-corrosion products are outstanding and rapidly expanding.
Polytetrafluoroethylene (PTFE) has a high degree of chemical stability. He has almost all commonly used strong corrosion and hydroxide chemical substances, and also has the characteristics of high temperature resistance, so it is an aspirational anti-corrosive material. Through the discussion of processing and molding skills, the use of polytetrafluoroethylene anti-corrosive products in the industry has become more and more widespread.
Polytetrafluoroethylene anti-corrosive products can replace many alloy materials, increase equipment working capacity, reduce downtime repairs, and are a kind of corrosion-resistant products with great development potential.
The emergence of PTFE lined pipe has basically solved the problem of industrial anticorrosion. Steel-lined PTFE pipes are mainly used in the chemical industry to transport highly corrosive media, strong acids and alkalis, etc., which can basically withstand any concentration and any kind. Acid and alkali salts and other corrosive media, and also resistant to high temperatures, can still work normally at temperatures up to 250 degrees. These characteristics are unmatched by other PTFE tube.
