Has good electrical insulation properties. When used in conjunction with cathodic protection, the anti-corrosion coating should have a certain ability to resist cathodic peeling strength. Has sufficient mechanical strength. To ensure that the coating is not damaged during handling and soil pressure. One of the basic methods for anti-corrosion steel pipes is to evenly and densely apply coatings on the surface of rust removed anti-corrosion steel pipes to isolate them from various corrosive media.

　　3PE anti-corrosion steel pipe is used for anti-corrosion and cold insulation engineering of various indoor and outdoor pipelines, heating pipelines, local air conditioning pipelines, chemical and other industrial pipelines. Overview: Since the emergence of 3PE decomposition materials in the 1930s, 3PE foam anti-corrosion pipes have been rapidly developed as a superior insulation and anti-corrosion material. Their application scope has become increasingly common, and they are widely used in various pipelines such as heating, cooling, oil transportation, and steam transportation due to their complex construction and clear energy-saving and anti-corrosion effects. Used in large quantities for various pipelines such as heating, cooling, oil transportation, and steam transportation. The company produces various anti-corrosion coatings, including IPN8710 polyurethane polyethylene anti-corrosion coating, epoxy coal tar anti-corrosion coating, and solvent-free epoxy resin anti-corrosion coating; We can undertake the anti-corrosion treatment of steel pipes with epoxy coal tar one cloth and three oils or (two cloth and four oils) on the inner and outer walls, cement mortar lining anti-corrosion pipes on the inner walls of steel pipes, and IPN8710 anti-corrosion processing. The company has advanced process equipment and complete testing methods. We have advanced testing equipment and established a comprehensive quality assurance system. Our products are widely used in anti-corrosion projects such as oil pipelines, natural gas pipelines, urban heating pipelines, water supply pipelines, and electricity. Participated in the completion of anti-corrosion and insulation projects for long-distance oil, gas, and water pipelines in China, and participated in the completion of anti-corrosion projects for pipelines exported to Indonesia, Sudan, Saudi Arabia, and South Africa.

　　The application scope of 3PE anti-corrosion steel pipes is as follows: sewage treatment: sewage treatment discharge pipes, sewage pipes, and biological pool anti-corrosion engineering agriculture: agricultural irrigation pipes, deep well pipes, drainage pipes and other network coal mines: 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. Starting from the construction of the Seninglan pipeline, through bidding and the localization of all 3PE anti-corrosion materials, the prefabrication price of 3PE anti-corrosion has significantly decreased, marking the beginning of an era of widespread application of 3PE anti-corrosion in China. So far, 20000 kilometers of buried steel pipes have been coated with 3PE anti-corrosion coating for external anti-corrosion. Overall, the anti-corrosion steel pipes produced by anti-corrosion steel pipe manufacturers have played a significant role to a certain extent, so their promotion and use will become more widespread in the later stage, and their prospects for future development are still very promising. To solve the severe water crisis in China, it is necessary to increase the sewage treatment rate as soon as possible by quoting large-diameter 3pe anti-corrosion steel pipes. At present, there are dozens of 3PE coating operation lines in China, which have the ability to process 3PE coatings on Φ 25-m steel pipes. 3PE anti-corrosion and insulation 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. Although chemical cleaning of large-diameter 3pe anti-corrosion steel pipes can achieve a certain level of cleanliness and roughness on the surface, their anchor lines are shallow and they are prone to environmental pollution. It has been recognized and used worldwide for over ten years.

　　The anti-corrosion coating of 3PE anti-corrosion steel pipes is crucial for the service life of buried pipelines. For pipelines of the same material, some may not corrode after being buried underground for decades, while others may leak within a few years. It's because they use different external anti-corrosion coatings. In the three-layer structure, the main function of the fusion bonded epoxy powder coating is to form a continuous coating film, directly bond with the surface of the steel pipe, and have good chemical corrosion resistance and cathodic stripping resistance; Reacting with the active groups of the intermediate layer adhesive to form a chemical bond, ensuring that the overall anti-corrosion layer has good adhesion at higher temperatures. The intermediate layer is usually a copolymer adhesive, which is mainly composed of polyolefin. Currently, ethylene based copolymer adhesives are widely used. The polar functional groups of the copolymer adhesive can react with the epoxy groups of the fusion bonded epoxy powder coating to form hydrogen bonds or chemical bonds, forming a good bond between the intermediate layer and the bottom layer; The non-polar ethylene portion has a good affinity with the surface layer polyethylene, so the intermediate layer also has good bonding performance with the surface layer. The main function of polyethylene surface layer is to provide mechanical protection and anti-corrosion, which is the same as the traditional two-layer structure polyethylene anti-corrosion layer. The 3PE anti-corrosion steel pipe consists of the following three layers in a three-layer structure: the bottom layer is fusion bonded epoxy; The main function of the adhesive fusion bonded epoxy powder coating in the middle layer is to form a continuous coating film, which is directly bonded to the surface of the steel pipe and has good chemical corrosion resistance and cathodic stripping resistance; Reacts with the active groups of the intermediate layer adhesive to form a chemical bond, ensuring that the overall anti-corrosion layer has good adhesion at higher temperatures. The intermediate layer is usually a copolymer adhesive, which is mainly composed of polyolefin. Currently, ethylene based copolymer adhesives are widely used. Meanwhile,; The surface layer is extruded polyethylene. The total thickness of the protective layer is approximately. In the three-layer structure 3PE anti-corrosion technology, all raw materials and Langfang 3PE anti-corrosion steel pipes have been localized due to the fast construction period. Epoxy powder used to be imported from the United States, but now China can produce it independently. In recent years, the paint industry has not only become increasingly competitive, but also influenced by numerous environmental inspections. In the face of such an environment, how to survive has become a major issue for paint companies. The future development of the paint industry will definitely move towards a green and environmentally friendly path.
