Gas 3pe anti-corrosion steel pipe reinforced grade 3pe anti-corrosion steel pipe price

Description :

　　Many people only know one thing about the uses of 3PE anti-corrosion steel pipes, but they do not know the other. Its function is really broad, and it is suitable for underground water supply and drainage, underground spraying, positive and negative pressure ventilation, gas drainage, fire sprinkler and other pipe networks in coal mines. Thermal power plant process water waste residue and return water transportation pipeline. The applicability of water supply pipelines for anti spray and sprinkler systems. Cable protection sleeves for power, communication, highways, etc.

　　3PE anti-corrosion spiral steel pipes are widely used in pipeline engineering fields such as petroleum, chemical, natural gas, heat, sewage treatment, water sources, bridges, steel structures, and marine water transmission pile driving.

　　3PE anti-corrosion spiral steel pipes have good insulation performance, with heat loss only 25% of traditional pipes. Long term operation can still save significant resources, significantly reduce energy costs, and have strong waterproof and corrosion-resistant capabilities. They do not require pipe trenches and can be directly buried underground or in water. Construction is also simple and fast, and the overall cost is relatively low. They also have good corrosion and impact resistance under low temperature conditions, and can be directly buried in frozen soil in certain environments.

　　The 3PE anti-corrosion spiral steel pipe coating, also known as the three-layer polyethylene anti-corrosion coating, is a new anti-corrosion steel pipe coating that cleverly combines the European 2PE anti-corrosion layer with the widely used epoxy powder anti-corrosion steel pipe coating (FBE) in North America. It has been recognized and used worldwide for over ten years.

　　The coating of 3PE anti-corrosion steel pipe is an epoxy powder anti-corrosion coating in contact with the bottom layer and the steel pipe surface, and a copolymer adhesive with branched functional groups in the middle layer. The surface layer is a high-density polyethylene anti-corrosion coating.

　　The 3PE anti-corrosion coating combines the high impermeability and mechanical properties of epoxy resin and polyethylene materials. So far, it has been globally recognized for its effectiveness Performance The pipeline anti-corrosion coating has been applied in many engineering projects.

　　Corrosion prevention of steel pipe inner wall:

　　There are two types of anti-corrosion for the inner wall of steel pipes: one is hot-melt epoxy resin powder anti-corrosion (high-temperature fusion bonding), and the other is liquid epoxy coating, commonly used liquid epoxy IPN8710 (room temperature cold spraying).

　　Anti corrosion spiral steel pipes are mainly used for the outer wall anti-corrosion of buried or underwater steel oil, gas, water, and heating pipelines. They are also suitable for anti-corrosion of various steel structures, docks, ships, water gates, gas storage tanks, refinery and chemical plant equipment, as well as waterproofing and leakage prevention of concrete pipes, sewage tanks, roof waterproof layers, bathrooms, basements, and other concrete structures.

　　Hardness index of anti-corrosion spiral steel pipe:

　　The ability of a metal material to resist the indentation of a hard object on its surface is called hardness. According to different testing methods and applicable ranges, hardness can be divided into Brinell hardness, Rockwell hardness, Vickers hardness, Shore hardness, microhardness, and high-temperature hardness. For anti-corrosion spiral steel pipes, three commonly used hardness types are Brinell, Rockwell, and Vickers.
