- Apr 20, 2019-

As for shan - jing natural gas pipeline and kushan oil pipeline, three layers of external anti-corrosion coating (PE) have been used recently in nearly two kilometers of pipeline for west-east natural gas transmission, a key national project.Three layers of PE are also used for the 67km high-pressure pipeline of shaanxi gas into tianjin, the 30km high-pressure natural gas pipeline of the outer ring road and the 122km pipeline of underground gas storage of the shaanxi-beijing line in tianjin.It has become the development direction of pipeline outer anti-corrosion coating in the future!3 PE anticorrosive pipe three-layer PE anticorrosive layer (3 PE) a combination of fusion bonded epoxy powder coating and extruded polyethylene fine properties of two kinds of anticorrosive coating, the interface characteristics of fusion bonded epoxy powder coating and chemical characteristics, and advantages of extruded polyethylene anticorrosive coating mechanical protection feature, so as to significantly improve their performance.
