3PE Pipe Manufacturing Facilities And Development Direction
Jan 17, 2017

3PE pipe has a very high tightness, long running can greatly save energy, reduce costs and protect the environment. Strong corrosion resistance capability, speed encountered Jane, uses life expectancy of up to 30-50. Under the condition of low temperature also has good corrosion resistance and impact resistance, PE low water absorption (less than 0.01%). Along with epoxy high strength, PE low water absorption and hot melt adhesive is soft and good, and has very high corrosion and reliability, but 3PE other than related advantage of more, which still have a relative disadvantage, the drawback is: compared with other weld material costs, cost is high.

From 3PE pipe in the later development of market analysis, in China, the three-layer PE has taken the lead in the oil and gas system to be applied. Have been built and the Shaanxi-Beijing natural gas pipeline Ku-Shan oil pipeline, recent national key project of West-East gas pipeline nearly 4000 km of pipelines are used outside a three-layer PE anticorrosive coating. In the city of Tianjin, Shaanxi gas into Tianjin and 67 km high-pressure pipeline and the outer ring 30 km high pressure natural gas pipeline, the Shaanxi-Beijing line 122 kilometers of underground gas storage pipeline is also used for three-layer PE. It has become the pipe external coating in the future direction of development.
