3PE anticorrosive steel pipe refers to 3-layer structure polyethylene coating (MAPEC) external anticorrosive steel pipe, which is a commonly used anticorrosive pipe in China. Other anti-corrosion methods include IPN8710, FBE epoxy powder and epoxy coal pitch. Generally refers to the corrosion of steel pipe outer wall.
Anticorrosive form of steel tube outer wall
3PE anticorrosion generally consists of three layers:
First layer epoxy powder (FBE>100um)
Second layer adhesive (AD) 170 ~ 250um
Third layer polyethylene (PE) 1.8 ~ 3.7mm
In actual operation, the three materials are mixed and integrated into one, which can be firmly combined with the steel pipe to form an excellent anticorrosive layer after processing. Its processing mode is generally divided into two types: winding type and round mold wrapping type.
