3PE steel pipe anticorrosion process flow chart detailed introduction

Pipeline three layer PE anti-corrosion structure: the first layer of epoxy powder (FBE > 100um), second layers of adhesive (AD) 170 ~ 250um, third layers of polyethylene (PE) 2.5 ~ 3.7mm. The three materials are one of the materials, and the steel pipe is firmly combined with the formation of excellent corrosion protection layer.

Range of the diameter of phi 159 ~ Phi 1220 2PE anti-corrosion: pipeline layer PE anti-corrosion structure, the first layer adhesive (AD), the second layer of polyethylene (PE), two kinds of materials as a whole, the thickness of each layer and three layer PE.

3PE anticorrosion layer is composed of epoxy powder primer, intermediate adhesive layer, outer layer of polyethylene composite consisting of a kind of anticorrosion structure, with high mechanical strength, excellent electrical insulation properties, high degree of mechanization of the production line operation, technological parameters is relatively stable, does not pollute the environment, etc., in the domestic in recent years, the focus of pipeline anticorrosion engineering has been widely used.
