Steel lined PTFE pipes and fittings are renowned as the "King of Plastics" and have excellent temperature and corrosion resistance. They are ideal transportation equipment for highly corrosive organic solvents such as nitric acid, sulfuric acid, hydrofluoric acid, phosgene, chlorine, aqua regia, mixed acid, bromide, etc. Our company provides free pipeline design, on-site surveying and installation guidance.

After years of exploration and long-term use by customers, our company has successfully developed steel lined PTFE pipes and accessories that can operate stably under extreme negative pressure conditions at high temperatures (within 150 ℃) for a long time. This has solved the problem of steel lined PTFE pipes and accessories not being able to withstand negative pressure in the past, and has been widely used in many high-temperature and high negative pressure systems such as distillation.

Series parameters: 1. Positive pressure pipeline: Pressure rating: 0-2.5Mpa

Nominal diameter: DN20-DN400 (larger specifications used for lining PTFE tower section processing)

Temperature resistance: -80~180 ℃

Processing technology: straight pipe - composite flange, the outer diameter of PTFE pipe is 1-1.5mm larger than the inner diameter of steel pipe

Accessories (elbows, tees, reducers, etc.) - Full mold sintering

2. Negative pressure pipeline: pressure rating: can withstand up to the limit of negative pressure

Nominal diameter: DN20-DN300

Temperature resistance: ≤ 150 ℃

Processing technology: straight pipe (DN20-DN50) - thick walled PTFE pipe composite flange, δ= 4-5

Nominal diameter: DN10~600mm
