(1) 3PE coating anti-corrosion technology is used in many major steel pipe laying projects. The products of this project comply with the national energy-saving policy. 3PE anti-corrosion steel pipes have increased the service life of the original steel pipes by more than 1 time due to the 3PE anti-corrosion coating technology. The increase in service life is also the use of energy saving.
(2) 3PE anti-corrosion technology adopts relatively good domestic production technology and energy-saving equipment, with less pollution and low energy consumption. In addition, the product quality reaches a relatively high level, which can meet the quality requirements of the downstream market for products. The product market space is broad, the development prospects are good, and there is a lot of room for development.
(3) In recent years, 3PE anti-corrosion steel pipes have been greatly utilized in the steel pipe industry, and major national projects have adopted 3PE coating technology.
Promotion of ordinary three-layer PE anti-corrosion steel pipe anti-corrosion technology:
(1) 3PE anti-corrosion technology enables the location of the technology to have high-tech resources because the nature of the enterprise must achieve stable electricity.
(2) Natural gas is transported under pressure at the starting compressor station and compressor stations along the line. The gas transmission pressure is 70-80 kg/cm2, and the total length of the steel pipe can reach thousands of kilometers. The gas transmission steel pipe is made of steel pipes connected by electric welding. There are many types of steel pipes, including seamless steel pipes, spiral steel pipes, and straight seam steel pipes. Seamless steel pipes are suitable for steel pipes with a diameter of less than 529 mm, and spiral steel pipes and straight seam steel pipes are suitable for large-diameter steel pipes.
(3) The cross-sectional structure of the steel pipe of the gathering and transportation steel pipe is complex, with inner coating-steel pipe-outer insulation layer-thermal insulation (cold insulation) layer; the simple one has only steel pipe and outer insulation layer, and the inner wall coating and thermal insulation (cold insulation) layer are determined according to the gas transmission process.
(4) The service life of ordinary three-layer PE anti-corrosion steel pipe is a concern of people. More and more people are involved in production for this issue. 3pe anti-corrosion steel pipe has a complete set of production technology abroad, and its service life has also attracted people’s attention. The three-layer polyethylene anti-corrosion layer (3pe) combines the excellent properties of fused epoxy powder coating and extruded polyethylene anti-corrosion layer.
