3PE anti-corrosion spiral steel pipe is a kind of 3PE anti-corrosion steel pipe. The mother pipe of this kind of steel pipe is spiral steel pipe, and other anti-corrosion structures are the same as 3PE anti-corrosion steel pipe.
3pe anticorrosive spiral steel pipe anticorrosive structure: the first layer of epoxy powder (FBE> 100um), the second layer of adhesive (AD) 170 ~ 250um, the third layer of polyethylene (PE) 2.5 ~ 3.7mm. The three materials are integrated into one body, and are firmly combined with the steel pipe to form an excellent anticorrosive layer.
The diameter range of 3pe anti-corrosion spiral steel pipe is Φ60 ～ Φ1420.
The production process of 3PE anti-corrosion spiral steel pipe is as follows: the bare pipe is subjected to blasting and rust removal after intermediate frequency heating, after the rust removal inspection, the heating is performed again, and the spraying operation is carried out at a certain temperature, followed by powder spraying, and then the adhesive Spraying, and finally polyethylene spraying.
3pe anti-corrosion spiral steel pipe is widely used in pipeline engineering fields such as petroleum, chemical industry, natural gas, heat power, sewage treatment, water source, bridge, steel structure, marine water piling, etc.
