There are two typies of pipe lined: 1. Pipe tight lining. It is commonly known as pull tube, that is, tetrafluoro-pipe slightly larger than the steel tube inside diameter, through mechanical traction lining into the steel tube 2.Pipe loose lining. that is the outer diameter of the tetrafluoro pipe is slightly smaller than the inner diameter of the steel pipe, which is directly lined into the steel pipe through manual insertion.

main material: – PTFE (F4) is suitable for conveying strong corrosive medium ≤120℃, such as dilute HCl, HNO3,H2SO4,HF,NaOH, etc – PE service temperature ≤80℃, suitable for general weak corrosive medium transport, corrosion resistance is general – PP and PO service temperature ≤100℃, suitable for a small amount of solvent corrosive medium transport, corrosion resistance is generally

The mould is put into the pipe fitting, and the tetrafluorin powder is loaded into it for compaction forming.After demoulding, it is sintered and solidified in a high temperature furnace, and then cooled to form.

Main material: – PTFE F4 is suitable for conveying strong corrosive medium ≤150℃, such as dilute HCl, HNO3,H2SO4,HF,NaOH, and so on. – PFA use for conveying strong corrosive media ≤200℃, other characteristics are similar to PTFE

The surface of the pipe fittings is pretreated, then the pipe fittings is heated, ETFE powder is put into the pipe after the temperature reaches the standard, ETFE in the melt state is uniformly attached to the inner wall of the equipment through 3D rotation, and finally cooling and shaping. Main material: ETFE(F40), for conveying ≤150℃ strong corrosive medium,such as dilute HCl, HNO3,H2SO4,HF,NaOH, and so on. Normally can resist micro – negative pressure
