Product Structure: Steel PTFE tube is used as the matrix of ordinary carbon steel, lined with excellent chemical stability of thermoplastic PTFE (Teflon or abbreviation for [PTFE, F4]) plastics, through a specific process with . It has both the mechanical properties of steel, but also highly corrosion resistant plastic tetrafluoroethylene, slow fouling, easy growth of microorganisms features, is ideal for pipeline transportation acid, alkali, salt, and there is a strong corrosive industrial gases and other media. Tetrafluoroethylene-lined metal hose connectors at both ends: including threaded joints, flanged, quick connect fittings. Both ends of the flange sealing surface full of tetrafluoroethylene material to ensure safe and reliable delivery hose (to negative). Tetrafluoroethylene lined metal hose range of applications: for strong corrosive gases and liquids at high temperatures, other types of plastic composite pipe and metal pipe discomfort transmission medium, steel Teflon complex. Laminate tube are applicable, polyvinylidene fluoride based composite steel pipe suitable conveying corrosive medium at the operating temperature -40 ℃ ~ + 150 ℃, such as: high chemical stability: can withstand all the strong acid, including aqua regia, hydrofluoric role alkali, strong oxidizing agents, reducing agents and various organic solvents acid, concentrated hydrochloric acid, nitric acid, fuming sulfuric acid, an organic acid and the like. Ideal for high-purity chemicals feed use, corrosive fluids, solvents and other chemicals * liquid delivery * various high-temperature steam transport food, brewing and other industries high insulation, high mechanical piping vibration ultra pure liquids, pure water desalination industry pipe piping widely used in machinery, electronics, automotive, aerospace, chemical, computer, electric, military, communications and other important scientific and technological industries, such as micro-transformers.

Low temperature - with good mechanical toughness; even if the temperature dropped to -100 ℃, but also to maintain a 5% elongation. Corrosion - for most chemicals and solvents, showing an inert, resistant to acid and alkali, water and various organic solvents. Weather - plastic in the best aging life. High lubrication - is a solid material in the lowest coefficient of friction. Not adhered - solid material in the minimum surface tension, does not adhere to any substance. Non-toxic - with physical inertia, as a long-term implantation of artificial blood vessels and organs of the body with no adverse reactions
