Manufacturer direct sales of 3pe anti-corrosion steel pipe, 3pe anti-corrosion spiral steel pipe, three-layer PE anti-corrosion steel pipe

Description :

　　The company has three steel pipe factories with production lines for spiral steel pipes, anti-corrosion, insulation, coating, and pipe fittings. They produce double-sided submerged arc spiral steel pipes with diameters of 219-3620mm and wall thicknesses of 5-40mm, as well as two seamless hot expansion production lines with diameters of 32-1220mm. The products are mainly used for fluid pipeline transportation pipelines such as oil, natural gas, coal gas, and steam, as well as supporting projects such as heating, chemical, refrigeration, wellbore casing, and pile driving.

　　The insulation plant has 8 production lines of polyurethane insulation pipes, mainly producing directly buried steel sheathed steam insulation pipes, directly buried polyurethane foam insulation pipes and other series of products. The anti-corrosion factory has 3 3PE anti-corrosion production lines, producing 2PE/3PE anti-corrosion steel pipes, epoxy coal tar (one cloth, two oils, two cloths, three oils, three cloths, five oils, etc.) steel pipe inner wall IPN8710 drinking water pipeline anti-corrosion and cement mortar lining anti-corrosion, plastic lined anti-corrosion steel pipes, and coated composite pipes. Epoxy powder anti-corrosion steel pipe, TPEP anti-corrosion steel pipe and other series of products. The pipe fittings factory has four production lines, mainly producing various materials such as elbows, tees, reducers, reducers, heads, blind plates, flanges, corrugated compensators, metal hoses, supports and hangers, waterproof sleeves, etc. It has provided products and services for national key projects such as petrochemicals, electricity, heat, water conservancy, natural gas, chemical industry, shipbuilding, and pharmaceuticals, and has won good honors.

　　3PE anti-corrosion pipe is suitable for underground coal mine water supply and drainage, welding flange underground spraying, positive and negative pressure ventilation, gas drainage, fire sprinkler and other pipe networks. 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. Suitable for high-rise building water supply, heating network, water supply engineering, gas transmission, buried water transmission and other pipelines. Process pipelines for transporting corrosive media in industries such as petroleum transportation pipelines, chemical pharmaceuticals, and printing and dyeing. Anti corrosion engineering for sewage treatment discharge pipes, sewage pipes, and biological tanks. It can be said that 3PE anti-corrosion steel pipes are essential for the current construction of agricultural irrigation pipes, deep well pipes, drainage pipes and other networks, and it is believed that with the extension of technology, they will have even more brilliant achievements in the future In the early stage of introducing 3PE coating technology, China Petroleum Engineering Technology Research Institute formulated the Chinese 3PE coating construction acceptance specifications in April 1995, referring to DIN30670-1991 and NFA49-710 (March 1988 edition), for the construction of Shaanxi Beijing pipeline and Kushan pipeline. In the same year, it was upgraded to the industry standard SY/T4013-1995. After several years of engineering construction summary and practice, it was revised to SY/T0413-2002 in 2001 and implemented from August 1, 2002. At the beginning of the standard formulation, based on the actual situation in China, high-density polyethylene was the main type of polyethylene, and the Vicat softening point was set to not be less than 110 ℃; The thickness of the external anti-corrosion layer is determined according to the German standard DIN30670-1991, which mainly uses low and medium density polyethylene. The impact resistance strength of the 3PE anti-corrosion layer has been greatly improved, ensuring the construction quality of the Shaanxi Beijing pipeline and the Kushan pipeline. SY/T0413-2002 has also significantly improved the peeling strength and impact resistance indicators of the 3PE anti-corrosion layer, and clearly stipulated the mechanical strength and weather resistance of the 3PE anti-corrosion layer based on the content of some special materials such as carbon black. The sampling frequency of the joint peeling strength (i.e. the peeling strength of the heat shrink sleeve and heat shrink tape to the primer steel) has also been increased, contributing to ensuring the quality of the external anti-corrosion coating of the pipeline.
