Fluorine-lined pipes and fittings enjoy the reputation of "Plastic King". They have excellent temperature resistance and corrosion resistance. They are ideal conveying equipment for highly corrosive organic solvents such as nitric acid, sulfuric acid, hydrofluoric acid, phosgene, chlorine, Aqua regia, mixed acid, bromide and so on.

Fluorine-lined pipes are lined with fluorine in steel pipes. They are divided into moulded steel-lined tetrafluoro pipes and pipe-lined steel-lined tetrafluoro pipes.

Molded pipe: mainly through the PTFE powder molding, through the mold, water pressure molding, through the oven baking. This kind of pipeline is usually used in the case of high negative pressure and bad medium environment. The effect is remarkable, but the relative cost is also high.

Pipe lined fluorine pipeline: that is to say, it is made of push tube (produced by tetrafluoro pipe machine, with uniform wall thickness and good density) which is directly covered with steel tube and then processed and turned over at both ends. This kind of pipeline is relatively cheap and suitable for medium environment with relatively peaceful environment.
