3PE anti -corrosion steel pipe is a steel pipe that has a mother material including seamless steel pipes, spiral steel pipes and straight steel pipes that are processed by anticorrosive coating. The three -layer polyethylene (3PE) anticorrosive coating is widely used in the oil pipeline industry with its good corrosion resistance, water -resistant and gas permeability, and mechanical properties.
3PE anticorrosion is generally composed of 3 layers of structure:
The first layer of epoxy powder (FBE> 100um)
The second layer of adhesive (AD) 170 ～ 250um
The third layer of polyethylene (PE) 1.8 ～ 3.7mm
In the actual operation, the three materials are mixed into one, and the processing with the steel pipe is firmly combined with the steel pipe to form an excellent anticorrosive layer. Its processing method is generally divided into two types: winding type and round mold covering type.
3PE anti -corrosion steel pipe coating is also (three layers of polyethylene anticorrosive coating). It is a new kind of anti -corrosion in Europe's 2PE anticorrosive layer and North America's extensive use of epoxy powder anti -corrosion steel pipe coating (FBE) Steel pipe coating. It has been recognized and used in the world for more than ten years.
