3pe anti-corrosion steel pipe manufacturer in stock

Description :

　　Polyethylene three-layer structure protective layer, also known as three-layer PE/PP. It is an advanced external anti-corrosion technology introduced in recent years. Its structure consists of three layers: the bottom layer is fusion bonded epoxy, the middle layer is adhesive, and the surface layer is extruded polyethylene. The three-layer PE anti-corrosion layer combines the interface characteristics and chemical resistance of epoxy coating with the mechanical protection characteristics of extruded polyethylene anti-corrosion layer, significantly improving their respective performance. 3PE anti-corrosion steel pipe base materials include seamless steel pipes, spiral steel pipes, and straight seam steel pipes. The three-layer polyethylene (3PE) anti-corrosion coating has been widely used in the petroleum pipeline industry due to its excellent corrosion resistance, water vapor permeability resistance, and mechanical properties. 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.

　　The three-layer polyethylene coating anti-corrosion layer (3PE) combines the excellent properties of fusion bonded epoxy powder coating and extruded polyethylene anti-corrosion layer. It combines the interface characteristics and chemical resistance of fusion bonded epoxy powder coating with the mechanical protection characteristics of extruded polyethylene anti-corrosion layer, 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 service life of buried pipelines to 50 years, and is currently considered as an external anti-corrosion technology for pipelines internationally. In China, three-layer PE has been first applied in the oil and gas system. It has become the development direction of external anti-corrosion coatings for pipelines in the future. 3PE anti-corrosion steel pipes have always been a concern for the service life of 3PE anti-corrosion steel pipes, and more and more personnel are appearing in production to address this issue. 3PE anti-corrosion steel pipes have a complete set of production technology abroad, and their service life has also received people's attention. It can be said that 3PE anti-corrosion steel pipes are essential in current construction, and we believe that with the extension of technology, they will have even more brilliant achievements in the future.

　　From practical usage, if the pipeline is usually at room temperature and filled with water, the corrosion on the inside of the weld is usually not very severe. But if the water is cut off or the heating water is supplied, the degree of corrosion is still quite severe, and the construction efficiency is high; There is no solvent evaporation during the construction process, which is both safe and environmentally friendly. For small-scale pipeline coating renewal projects, manual brushing or small two-component airless spraying machines can be used for construction; For large-scale pipeline coating renewal projects, online spraying equipment for pipelines can be applied. This equipment was successfully applied in North America in the 1990s, when it was used to renew the anti-corrosion coating of 120km of old pipelines, and the effect was quite ideal. IPN8710 anti-corrosion steel pipe uses heavy-duty anti-corrosion coating as a two-component coating, with Group A base material: resin, initiator; Group B base materials: active monomers, catalysts. When group A and group B are mixed in equal quantities, the three networks interpenetrate at the molecular level to form an interpenetrating polymer network (IPN) structure, producing a synergistic effect. The coating forming network has strong adhesion, good flexibility, and resistance to corrosive media such as acid, alkali, and salt. Further improving the toughness, strength, adhesion, impermeability, and chemical inertness of the coating, the coating has better performance. By forming IPN to improve the properties of polymers, it is a new type of polymer blending technology.
