Fluorine-lined pipes and accessories are renowned as the "King of Plastics," boasting excellent temperature resistance and corrosion resistance. They are ideal for conveying highly corrosive media such as nitric acid, sulfuric acid, hydrofluoric acid, phosgene, chlorine gas, aqua regia, mixed acids, bromides, and other organic solvents.

Fluorine-lined steel pipes, which involve lining steel pipes with fluorine material, are categorized into molded steel-lined PTFE pipes and steel-lined PTFE pipe linings.

Molded pipes: Primarily made by molding polytetrafluoroethylene powder through molds, then formed under water pressure and baked in an oven. Such pipes are commonly used in situations with high vacuum and harsh medium environments, showing significant effectiveness, although their cost is relatively high.

Fluorine-lined pipe: This is a push-fit pipe (manufactured using PTFE pipe extrusion machines, with uniform wall thickness and good density) that is directly slipped over a steel pipe, then processed and flipped at both ends. This type of pipe is relatively inexpensive and suitable for relatively peaceful medium environments.
