Steel-lined PTFE pipes and accessories, renowned as the "King of Plastics," boast excellent temperature and corrosion resistance. They are ideal for conveying highly corrosive media such as nitric acid, mixed acids, bromides, and other organic solvents. The steel-lined PTFE pipes and accessories can operate stably under extreme vacuum conditions at high temperatures (up to 150℃) for extended periods, addressing the previous drawback of not being able to withstand vacuum in steel-lined PTFE pipes and accessories. They have found wide application in many distillation systems and other high-temperature, high-vacuum environments.

Chemical Properties of Steel Lined PTFE Pipe:

Resistance to atmospheric aging: Excellent radiation resistance and low permeability: Maintains surface and performance integrity after long-term exposure to the atmosphere.

Non-flammable: Oxygen Index below 90.

Acid and alkali resistance: Insoluble in strong acids, alkalis, and organic solvents.

Antioxidant property: Resistant to corrosion by strong oxidizing agents.

Corrosion Resistance: The steel-lined PO pipe can withstand almost all chemical media, including the corrosion from concentrated nitric acid and aqua regia, except for molten lithium, potassium, sodium, chlor trifluoride, oxygen trifluoride at high temperatures, and high-velocity liquid fluorine. It can operate continuously at temperatures ranging from 230℃ to 250℃.
