Henan lined steel pipe liner pe pipe lining po

Technical parameters Henan lined steel pipe lining material lining pe po steel pipe lining plastic-lined steel pipe industry State-run pipeline: F4, F46, PO, PE shell material: seamless steel pipe, Q234- steel welding work pressure: PN0.6- 1.6MPa Flange Standard: HG20593-97 Standard Fittings Executive Standard: HG-20528-1992 HG / T2437-2006 HG / T21562-1994 steel liner polyethylene (PE) composite pipe performance: medium temperature: -25 ℃ ~ + Media 105 ℃ Working pressure: Positive pressure 2.5MPa; negative 90KPa Series Features: non-toxic and anti-temperature resistance, low temperature resistance, vacuum, vacuum-resistant corrosion-resistant, anti-aging, impact resistance, surface smoothness combined with strong. Good general acid salt of an organic solvent properties, for conveying corrosive gases, liquids and solids liquid slurry medium. The products are widely used in chemical, biological, electric power, metallurgy, pharmaceutical, food, environmental protection and other fields, in the -20 ℃ -105 ℃ to replace rubber porcelain, glass, steel, stainless steel and plastic panels lining the ideal material for steel-lined polyolefin ( PO) composite pipe performance: medium temperature: -25 ℃ ~ + 105 ℃ media Working pressure: Positive pressure 2.5MPa; negative 90KPa Series Features: non-toxic and anti-temperature resistance, low temperature resistance, vacuum, vacuum-resistant corrosion resistance aging, impact resistance, surface smoothness combined with strong. Good general acid salt of an organic solvent properties, for conveying corrosive gases, liquids and solids liquid slurry medium. The products are widely used in chemical, biological, electric power, metallurgy, pharmaceutical, food, environmental protection and other fields, in the -20 ℃ -105 ℃ is an ideal material for rubber lined porcelain, glass, steel, stainless steel and plastic panels replaced. Steel liner PTFE (f4) composite pipe PTFE (Teflon or the abbreviation of [PTFE, F4]), Known as / commonly known as "plastics king", Chinese trade name "Teflon", "Teflon Dragon, "" Teflon, "and so on. It is made by polymerization of tetrafluoroethylene polymers, has excellent chemical stability, corrosion resistance (corrosion resistance is one of the world's best materials can, in addition to the molten metal and liquid sodium fluorine, the ability of other All chemicals, boiling water is not from the king changes, widely used in a variety of needs anti-acid and organic solvents), tightness, high lubrication viscosity, electrical insulation and good anti-aging endurance, high temperature ( long-term work at + 250 ℃ to -180 ℃ temperature). Performance: Low temperature - with good mechanical toughness; even if the temperature drops to -196 ℃, 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. Weatherability - the best plastic aging life. High lubrication - is a solid material in the lowest coefficient of friction. Not adhere to - is a 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 without adverse reaction.
