Description :

　　Manufacturer of epoxy zinc rich anti-corrosion steel pipes, epoxy zinc rich anti-corrosion steel pipes, epoxy zinc rich paint anti-corrosion steel pipes, CZ-9 zinc rich paint anti-corrosion steel pipes, 3pe reinforced anti-corrosion steel pipes, ordinary polyethylene anti-corrosion steel pipes, epoxy coal tar anti-corrosion steel pipes, ambient temperature wrapped PE anti-corrosion steel pipes, etc. Our company has advanced production lines in China. Welcome to inquire and cooperate by phone Anti corrosion steel pipe products are used in coal mines for underground water supply and drainage, underground spraying, positive and negative pressure ventilation, pumping, fire sprinkler and other pipe networks. Epoxy coal tar is commonly used for anti-corrosion. Power plants: Waste water and return water pipelines for thermal power plants are often coated with epoxy paint for corrosion prevention. Firefighting: For the applicability of water supply pipelines in sprinkler and sprinkler systems, hot-dip galvanizing is often used for corrosion prevention. Highways: Cable protection sleeves for power, communication, highways, etc. Municipal engineering: suitable for high-rise building water supply, heating network, water supply engineering, gas transmission, buried water transmission and other pipelines, often using epoxy paint, two cloth, three oil anti-corrosion and cement mortar anti-corrosion. Petroleum: Process pipelines for transporting corrosive media in industries such as petroleum transportation pipelines, chemical, printing and dyeing, etc., often use E anti-corrosion. Sewage treatment: Epoxy paint is commonly used for anti-corrosion of sewage treatment discharge pipes, sewage pipes, and biological tanks. Agriculture: Agricultural irrigation pipes, deep well pipes, drainage pipes, and other networks often use cement mortar for corrosion prevention. Epoxy zinc rich anti-corrosion paint is mainly suitable for the primer layer of steel pipes, storage tanks, steel structures, containers, ships, marine platforms, port facilities, and harsh corrosive environments. It is used in conjunction with corresponding intermediate and topcoats to form a composite anti-corrosion layer.

　　Epoxy zinc rich anti-corrosion steel pipe diameter range

　　(1) The upper and lower limits of the adhesive layer thickness. According to Table 2.0.2 of the standard, the thickness is 170-250 μ m. For the circular mold wrapping operation line, this thickness value is not a problem; For the winding operation line, this thickness range cannot be guaranteed. The material extruded from the winding operation line is aunt sheet, and if its thickness is greater than 170 μ m, the edge overlap must exceed 250 μ m. If it is required to meet the current industry standard requirements, the thickness of the sheet material should not exceed 60 μ m when extruding the adhesive layer, and multi-layer overlap should be used to meet the industry standard requirements. Otherwise, the adhesive layer thickness cannot be guaranteed to be 170-250 μ m. Therefore, the upper and lower limits of the adhesive layer thickness should differ by at least twice.

　　(2) The name and specifications of copolymer adhesive. At present, the adhesive used for 3PE anti-corrosion in China is actually graft adhesive, and copolymer adhesive is actually the first adhesive used for 3PE anti-corrosion. It is a product of grafting solid polyethylene with polyacrylic anhydride, so it should be called graft adhesive more appropriately; At present, there are only four indicators for copolymer adhesive in the industry standards, which cannot fully reflect the processing performance of the adhesive. At least two indicators, tensile strength and elongation at break, should be added to ensure the processing performance of the adhesive.

　　(3) Polyethylene thermal aging performance indicators. The heat aging resistance of medium polyethylene needs to be tested for 100 or 200 days. When it is necessary to sample and inspect the performance of polyethylene during the production process, the experimental period is too long and there is no operability to speak of. It is worth studying whether the thermal oxidation induction period value can be used instead. If the oxidation induction period can be used instead of traditional thermal aging performance testing, it will greatly shorten the sampling time. Whether changing F50 to F0, which is also resistant to environmental stress cracking, can shorten the inspection cycle should also be explored

　　Note: White rust (zinc salts) may form on the surface of zinc rich paint film after prolonged recoating, interval time, or in industrial atmosphere or marine climate environments. If this occurs, the coating should be treated with cleaning grade sandblasting or power tools, sandpaper, etc. before applying paint to remove all zinc salts and dirt.
