PTFE Lined Pipe Features RANA's PTFE lined pipeline has excellent temperature resistance and corrosion resistance, and is an ideal conveying equipment for strong corrosive media such as nitric acid, sulfuric acid, hydrofluoric acid, phosgene, chlorine, aqua regia, mixed acid, bromide and other organic solvents. Steel lined PTFE pipes and fittings that can run stably under high temperature (within 150°C) extreme negative pressure conditions for a long time solves the shortcomings of previous steel-lined PTFE pipes and fittings that cannot withstand negative pressure. The system has been widely used.
