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 ofanticorrosive coating, the interface characteristics stainless steel shower safety handle 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.

So as the outer protective layer of buried pipeline is very superior. Completed the shanxi-beijing natural gas pipeline in our country and the ku-shan oil pipeline, the recent national key project of west to east gas pipeline almost 4000 kilometers outside the pipeline adopts three layer PE anticorrosive coating.

Hunan great steel pipe co.,ltd is the good supplier of 3PE coating big diameter sprial   steel pipe. According to relevant data, three layer PE can make the life of the buried pipeline up to 50 years, at present, is considered to be zui advanced in the world outside the pipe anticorrosion technology. In our country, three layer PE has already applied in the oil and gas system
