3PE anti-corrosion
seamless steel pipe processing methods generally sub-winding type and round mold-covered two. The three-layer polyethylene coating (3PE) combines the excellent properties of both fused epoxy powder coating and extruded polyethylene coating, the interface properties and chemical resistance of fused epoxy powder coating, and squeeze Combined with the advantages of mechanical protection of polyethylene coating, etc., thereby significantly improving their performance. Therefore, as a buried pipeline outer protective layer is very superior. According to the information, three-tier PE can make buried pipe life of 50 years, at present, internationally recognized as advanced pipeline anti-corrosion technology. In China, the three-tier PE has taken the lead in the application of oil and gas system. China has built the Shaanxi-Beijing natural gas pipeline and the reservoir pipeline, near the national key project of nearly 4,000 km West-East pipeline are used three layers of PE anti-corrosion coating. In Tianjin Municipality, 67 kilometers high-pressure gas pipeline into Shaanxi and Shaanxi, and 30 kilometers high pressure natural gas pipeline from Outer Ring Road. The 122 kilometers pipeline of underground gas storage in Shaanxi-Beijing line is also a three-layer PE. 3PE anti-corrosion (three polyethylene) process is the advanced anti-corrosion technology introduced from abroad in the late 90s of last century, its full name is fused epoxy / extruded polyethylene protective structure. 3PE anti-corrosion technology combines the excellent properties of epoxy coating and extruded polyethylene two kinds of anti-corrosion coating, the epoxy coating interface properties and chemical resistance and extruded polyolefin anti-corrosion layer mechanical protection characteristics, etc. combined, Thus significantly improving their performance. Its characteristics: high mechanical strength, wear resistance, corrosion resistance, heat resistance, cold resistance, can be applied to 150 degrees medium, are adapted to the cold zone. Therefore, 3PE coating is the ideal line of buried pipeline protection. According to the authoritative department testing, buried pipelines with 3PE anti-corrosion technology can last up to 50 years.

In China, the three-tier PE has taken the lead in the application of oil and gas system. China has completed the Shaanxi-Beijing natural gas pipeline and the reservoir pipeline transportation, the recent national key project of nearly 4,000 km west-east pipeline are used three layers of PE anti-corrosion coating. In Tianjin Municipality, 67 kilometers high-pressure gas pipeline into Shaanxi and Shaanxi, and 30 kilometers high pressure natural gas pipeline from Outer Ring Road. The 122 kilometers pipeline of underground gas storage in Shaanxi-Beijing line is also a three-layer PE. It has become the future direction of pipeline coating development! 3PE anticorrosion steel pipe three-layer structure of polyethylene anticorrosive layer (3PE) combines the excellent properties of fused epoxy powder coating and extruded polyethylene two anticorrosive coating, fused epoxy powder coating interface properties and chemical resistance , Combined with the advantages of mechanical protection of the extruded polyethylene coating and the like, significantly improves their performance. 3PE anticorrosive steel pipe possesses superior qualities such as light weight, high strength, heat insulation, sound insulation, fire retardant, cold resistance, antisepsis, non-absorbent and rapid construction. It has become the full adiabatic anti-corrosion in construction, transportation, kerosene, chemical, , Waterproof plugging, sealing and other indispensable information. 3PE anti-corrosion steel pipe used for all kinds of pipes in the room, dove co-heating pipes, local air-conditioning pipes, chemicals, pipelines and other industrial anti-corrosion, cold insulation works. Overview 3PE foam anticorrosive tube Since the 3PE decomposition of the information in the thirties, since the birth of a straight as a superior adiabatic antiseptic materials and the rapid development, its use is also more and more common, but also because of its complicated construction, energy saving and anti-corrosion effect is clear And was used in large quantities for a variety of heating, refrigeration, oil, steam and other pipelines. A large number for a variety of heating, refrigeration, oil, steam and other pipelines.
