产品详情

Steel-lined PO pipes, steel-lined PTFE pipes and fittings enjoy the reputation of "Plastic King", with excellent temperature resistance and corrosion resistance, and are ideal for nitric acid, sulfuric acid, hydrofluoric acid, phosgene, chlorine, Conveying equipment for strong corrosive media such as aqua regia, mixed acid, bromide and other organic solvents.Steel-lined PO pipes and fittings that can run stably at high temperature (within 150°C) under extreme negative pressure conditions for a long time solves the shortcomings of previous steel-lined PO pipes and fittings that cannot withstand negative pressure. has been widely used.Chemical properties of steel lined PO pipe: Atmospheric aging resistance: radiation resistance and lower permeability: long-term exposure to the atmosphere, the surface and performance remain unchanged.Incombustibility: The oxygen limit index is below 90.Acid and alkali resistance: insoluble in strong acids, alkalis and organic solvents.Oxidation resistance: can resist the corrosion of strong oxidants.Corrosion resistance: steel lined PO pipe, it can resist almost all chemical media, including concentrated nitric acid and Corrosion of aqua regia, it can work at a temperature of 230℃-250℃ for a long time.Steel polyvinylidene fluoride or other vinylidene fluoride composite pipes have good corrosion resistance to halogens, halogenated hydrocarbons, strong oxidants, boiling acids, alkalis, and various organic solvents, but are not resistant to fuming sulfuric acid, concentrated Corrosion of hot sulfuric acid and nitric acid, ketones, esters, amines and high temperature sulfonating agents above 90℃.
