3pe corrosion spiral steel pipe company, 3pe corrosion spiral steel pipe manufacturers, 3pe corrosion spiral steel pipe corrosion spiral steel pipe company offer 3pe, 3pe corrosion spiral steel pipe manufacturers, 3pe corrosion spiral steel pipe corrosion spiral steel pipe company offer 3pe, 3pe corrosion spiral steel pipe manufacturers, 3pe corrosion spiral steel pipe Quote 3PE anti-corrosion steel-related knowledge we have said a lot, almost already very comprehensive, and today we are once again under 3PE anti-corrosion steel pipe structure and its associated performance to explain, which 3PE anti-corrosion steel structure: the first layer ring oxide powder (FBE> 100um), the second layer of adhesive (copolymer rubber) 170 ~ 250um, a third layer of polyethylene (PE) 2.5 ~ 3.7mm. These three materials closely together, and with the steel firm to form an excellent coating. The 3PE anti-corrosion steel used on the market today is the use in different working environments, to slow or prevent any chemical, electrochemical action pipe outer medium or by the metabolic activity of microorganisms which erosion and deterioration in the outer wall of the coating 2 or 3 layers of polyethylene (3PE) to achieve pipeline corrosion, 3PE anti-corrosion steel 3-5 times longer life. Strengthen 3PE anti-corrosion steel with a high level of tightness, long-running can greatly save energy, reduce costs, protect the environment. Strong corrosion resistance, simple construction side has the speed, the service life of up to 30-50 years. At low temperatures also have good corrosion resistance and impact resistance, PE and low water absorption (less than 0.01%). Along with high strength epoxy, PE hot melt adhesive, low water absorption and good flexibility, high corrosion can be *, but 3PE related advantages in addition to more than, its still a relatively shortcomings, the drawback is: Compared with other mending material costs, the cost is high. 3PE steel from corrosion in the latter part of the development of market analysis point of view, China's demand for 3PE anti-corrosion steel is very impressive. In China, three PE has taken the lead in the oil and gas system has been applied. China has built the Shaanxi-Beijing natural gas pipeline and oil pipeline Kushan, recently nearly 4000 km pipeline is of key national projects have adopted a three-tier PE external corrosion coating. For the latter part of the development, the steel companies have a good grasp of the stock market have 3PE anti-corrosion steel.
