Steel lined PTFE pipes and fittings enjoy the reputation of “King of Plastics”, with excellent temperature and corrosion resistance, and are ideal for conveying strong corrosive media such as nitric acid, sulphuric acid, hydrofluoric acid, phosgene, chlorine, aqua regia, mixed acids, bromides and other organic solvents. Steel lined PTFE piping and fittings that can operate stably at high temperatures (within 150°C) under extreme negative pressure conditions for a long time have solved the shortcomings of previous steel lined PTFE piping and fittings that cannot resist negative pressure and are widely used in many distillation and other high temperature and high negative pressure systems.
The steel lined teflon push-pressure pipe is purely mechanical processing, compared with other steel lined teflon pipe processing technology, the steel lined teflon pipe produced has: high density, smooth surface, uniform thickness and other characteristics. The “high density” prevents the medium from penetrating and is not easily deformed in use; the “smooth surface” makes the medium flow resistance small and effectively prevents sticking; the “uniform thickness” makes the Steel lined PTFE pipe has high strength and good sealing performance at the flange. It is suitable for various concentrations of acids, alkalis, strong oxidants, aqua regia and other strong corrosive media.
