Manufacturer of polyethylene anti-corrosion steel pipes for internal and external anti-corrosion pipelines

Description :

　　Analysis of Production and Growth of 3PE Anti corrosion Steel Pipes for Gas Pipelines: To slow down or prevent the corrosion and deterioration of pipelines under the chemical and electrochemical action of external media or the metabolic activity of microorganisms, 2 or 3 layers of polyethylene (3PE) are coated on their outer walls to achieve pipeline anti-corrosion, and the service life of 3PE anti-corrosion pipes is extended by 3-5 times. 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. 3PE anti-corrosion pipeline is currently considered as the most advanced external anti-corrosion technology for pipelines. In China, three-layer PE has been first applied in the oil and gas system.

　　3PE anti-corrosion is a commonly used anti-corrosion method, in addition to 2PE, 2PP, 3PP. Their manufacturing processes are similar, but the raw materials are not the same. The characteristics of this anti-corrosion method are simple manufacturing process, good anti-corrosion effect, and low price. It is widely recognized as an anti-corrosion method in the pipeline manufacturing industry! In addition, our company has strong production equipment and can independently undertake anti-corrosion and insulation projects. We welcome new and old customers to call us for consultation! The anti-corrosion layer 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 is because they use different external anti-corrosion coatings 3PE anti-corrosion steel pipes. 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. The ultimate goodness in life is to be optimistic about life, happy about work, and excited about career.

　　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 outer wall anti-corrosion of oil, gas, water and heating pipelines is also applicable to various steel structures, docks, ships, water gates, gas storage tanks, equipment anti-corrosion in refineries and chemical plants, as well as waterproofing and leakage prevention of concrete structures such as concrete pipes, sewage tanks, roof waterproof layers, bathrooms, basements, etc. The standard mainly specifies polyethylene and high-density polyethylene. The 3PE anti-corrosion steel pipe follows the standard, and the processing methods for 3PE anti-corrosion steel pipes are generally divided into two types: winding and circular mold wrapping. The three-layer structure polyethylene anti-corrosion coating (3PE) combines the excellent properties of fusion bonded epoxy powder coating and extruded polyethylene anti-corrosion coating. It combines the interface characteristics and chemical resistance of fusion bonded epoxy powder coating with the mechanical protection characteristics of extruded polyethylene anti-corrosion coating, thereby significantly improving their respective performance. Therefore, as an external protective layer for buried pipelines, it is very superior. According to relevant information, three-layer PE can extend the lifespan of buried pipelines to 50 years, and is currently considered an advanced external anti-corrosion technology for pipelines.
