The three-layer structure of the anti-corrosion steel pipe polyethylene anti-corrosion layer combines the excellent properties of the sintered epoxy powder coating and the extruded polyethylene anti-corrosion layer. The interfacial properties and chemical resistance of the epoxy powder coating are combined with the mechanical protective properties of the extruded polyethylene anti-corrosion coating to significantly improve the respective properties. Therefore, it is very superior as an outer protective layer for buried pipelines. According to relevant information, three layers can extend the service life of buried pipelines to years. Currently, it is considered to be the most advanced pipeline external anti-corrosion technology in the world. In our country, three-layer systems have taken the lead in being applied in oil and gas systems. Our country's built Shaanxi-Beijing natural gas pipeline and Kushan-Shanxi oil pipeline, as well as the recent national key project West-East Gas Pipeline nearly one kilometer long, all use three layers of external anti-corrosion coating. In Tianjin, three kilometers of high-pressure pipelines from Shaanxi to Tianjin, kilometers of high-pressure natural gas pipelines on the outer ring line, and kilometers of underground gas storage pipelines on the Shaanxi-Beijing line also use three layers. It has become the development direction of the external anti-corrosion layer of pipelines in the future.
