3PE anti-corrosion steel pipe manufacturers craft Price

3PE anti-corrosion steel pipe three-tier structure of polyethylene anticorrosion coating (3PE) combines the good properties of the fusion bonded epoxy powder coating and two anti-corrosion layer extruded polyethylene, fusion bonded epoxy powder coating interface characteristics and chemical resistance mechanical protective characteristics, etc., and the extruded polyethylene coating together, thereby significantly improving their performance. Therefore, as the outer protective layer of buried pipelines is very superior. According to the information, the three-layer PE the buried pipeline life can reach 50 years, currently in the international arena is considered to be the most advanced pipe outer anticorrosion technology. In China, the three-layer PE has taken the lead in the oil and gas system. Shaanxi-Beijing natural gas pipeline has been built in China and the Treasury Shan pipeline, nearly 4,000 km of the national key projects in West-East pipeline with a three-layer PE External Coatings. In the 67 km high-pressure pipeline, Tianjin, Shaanxi gas into Tianjin Outer Ring Road 30 km high pressure gas pipeline, 122 km of underground gas storage in the Shaanxi-Beijing line pipeline also uses three-layer PE. It has become a pipeline external coating development direction 3PE anti-corrosion steel pipe manufacturing method in the future: the pipeline three PE anticorrosion structure: the first layer of epoxy powder (FBE> 100um), the second layer of adhesive (AD) 170 ~ 250um, and the third layer of polyethylene (PE) 2.5 to 3.7mm. Three of the integration, and combine to form an excellent anti-corrosion layer steel pipe firmly. Many factors affect the performance of the pipe 3PE anticorrosion layer, such as the layout of the various processes, equipment selection, surface quality, heating method, coating temperature, cooling, transmission accuracy, material properties and testing, poor control will result in coated layer adhesive force is small, too thin, defects such as cracking or bubbles, strict implementation of norms and scientific way of operating control deficiencies, it is vital to ensure that the yield of the anti-corrosion pipe [3-8] diameter range Φ60 Φ1420 wall thickness range between 2.5-18mm, which is a good corrosion protection methods, and generally improve the service life of 50 years, not only to extend the underground pipeline equipment replacement cycle, significant cost savings and provide a strong role for the state building! 3PE antisepsis is the most commonly used anti-corrosion method, in addition to 2PE 2PP almost 3PP their manufacturing process, just different ingredients, this anti-corrosion characteristics of the production process is simple, preservative effect, low prices, pipe manufacturing industry generally agree that the anti-corrosion method! In addition, the company has a strong professional production equipment to undertake anti-corrosion insulation works independently, and to welcome new and old customers call to plant consulting! 3pe anti-corrosion steel pipe (steel pipe) in different working environment, and slow or prevent the pipeline outside medium chemical, electrochemical action by the metabolic activity of the microbial erosion and deterioration coated on its outer wall layer 2 or 3 layer polyethylene (3PE) to reach the pipe anticorrosion 3pe anti-corrosion pipe service life 3-5 times longer. 3PE anti-corrosion steel pipe protective layer of polyethylene three-tier structure, also known as three PE (3PE) from abroad in recent years, advanced anti-corrosion technology. It called the fusion bonded epoxy / extruded polyethylene structural protection layer structure consists of the following three components: the ground floor of a fusion bonded epoxy (≥ 80μm); intermediate layer of adhesive (170-250μm); surface layer for extrusion polyethylene (about 2mm). The total thickness of the protective layer is approximately 1.8-3.7mm. The main role in the three-tier structure, fusion bonded epoxy powder coating: the formation of a continuous film, bonded directly to the steel surface, has good chemical resistance and resistance to cathodic disbondment performance; adhesive and the middle layer The reactive groups react to form a chemical bond, having good adhesion to ensure that the overall corrosion protective layer at higher temperatures. The intermediate layer typically is a copolymer binder, whose main component is a polyolefin, is currently widely used is a vinyl copolymer adhesives. The polar part of the functional groups of the copolymer adhesives, fusion bonded epoxy powder coating of epoxy groups can be reacted to produce hydrogen or a bond, The non-polar ethylene moiety and the surface layer of the intermediate layer and the bottom to form a good bond; polyethylene has a good pro cooperation with the intermediate layer and the surface layer also has a good bonding properties. The main role of the polyethylene surface layer from the mechanical protection and preservation, with traditional polyethylene coating of the two-story structure has the same effect.
