2PE/3PE anti-corrosion and single-layer PE anti-corrosion 1. 3PE
Anti-corrosion Pipeline three-layer PE anti-corrosion structure: the first layer of epoxy powder (FBE>100um), the second layer of adhesive (AD) 170~250um, and the third layer of polyethylene (PE) 2.5~3.7mm. The three materials are integrated and firmly combined with the steel pipe to form an excellent anti-corrosion layer. Pipe diameter range Φ60～Φ1420 2. 2. 2PE anticorrosion steel pipes with two layers of PE anticorrosion structure, the first layer of adhesive (AD), the second layer of polyethylene (PE), the two materials are integrated, and the thickness of each layer is the same as that of three layers of PE: SY/T0413-2002 Technical standard for polyethylene anticorrosion layer of buried steel pipes GB/T23257-2009 Technical standard for polyethylene anticorrosion layer of buried steel pipes 3. Single PE anticorrosion steel pipes single layer PE anticorrosion steel pipes adopt the paint coating process (also known as the curtain method), rotating the steel pipe after medium frequency heating. The top layer of the steel pipe is a container filled with polyethylene powder, which is formed by spraying on the outer wall of the steel pipe. Implement standard CJ/T120-2008 water-coated plastic composite steel pipe.
