Steel PTFE lined pipes, steel-lined PTFE pipes and fittings have the reputation of "Plastic King". They have excellent temperature resistance and corrosion resistance. They are ideal for nitric acid, sulfuric acid, hydrofluoric acid, phosgene, Transport equipment for strong corrosive media such as chlorine, aqua regia, mixed acid, bromide and other organic solvents. The steel-lined PTFE pipes and accessories that can operate stably under extreme negative pressure conditions at high temperatures (within 150°C) for a long time solves the shortcomings of steel-lined PTFE pipes and accessories that cannot withstand negative pressure. In many distillations and other high temperature and high negative pressure It has been widely used in the system.

Chemical properties of steel lined PTFE pipe:

Atmospheric aging resistance: radiation resistance and low permeability: long-term exposure to the atmosphere, the surface and performance remain unchanged.

Non-combustibility: The oxygen limit index is below 90.

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

Oxidation resistance: resistant to corrosion by strong oxidants.
