Guanghui Cangzhou Pipe Co., Ltd. was founded after two generations of two additional production line with internal and external pipeline corrosion, reaching nine pipe production lines, can be processed: 2pe / 3pe anticorrosive steel 2PP / 3PP anticorrosive steel FBE / 2FBE cement pipe corrosion epoxy powder mortar lining coal tar epoxy anti-corrosion steel pipe drinking water, non-toxic epoxy anti-corrosion steel pipe corrosion ipn8710 polyurea corrosion epoxy anti-corrosion steel pipe anti-corrosion epoxy micaceous iron pipe chlorinated rubber solvent-free anticorrosive epoxy anti-corrosion steel pipe corrosion HT515 steel products such as glass flake epoxy anti-corrosion steel pipe corrosion, etc., according to customer needs using a variety of materials seamless steel pipe spiral pipe straight seam steel pipe. 1, visual inspection, pre-processing, general steel by skilled workers to carry out visual analysis, examination by the root, if there is a serious mechanical damage steel, heavy leather, cracks, dents and other defects, compared with substandard products must be returned; check thread nozzle, when the nozzle appear flat mouth, we should be repaired, it can not be repaired in accordance with the waste treatment. 2, pipe rust, will be embalmed steel shipped to Shangguan platform operating line, and get rid of heat-treated steel flame surface moisture, oil, and other impurities, control the temperature between 40-60 degrees Celsius, with PW- 380 steel shot blasting machine rust and steel pipe after further processing, clean out the rust, oil, scale, etc., while the failure of the local polished. 3, after the grinding, dust applied to the outer surface of the steel pipe handling apparatus for secondary treatment, and the remaining dust handle clean rust powder, epoxy powder coating is then applied within 4 hours. 4. Preheat steel, epoxy powder coated before proceeding, should be preheated, according to the pipe diameter, and feeding speed, choose the right temperature, but be careful not to exceed 275 degrees. 5, adhesive coated with polyethylene tape winding, adhesive coated in epoxy powder gelling process; lateral winding process proceeds, to ensure the integrity of the polyethylene layer on the surface, and the lap portion of polyethylene and polyethylene on both sides of the weld full roll compaction. 6, circulating water cooling, after the end of production of steel pipe coating should be cooled swaging, irrigated by circulating anti-corrosion coating chamber cooling treatment finished steel pipe coating surface. 7, the cutting head to stay with cooling water pipe corrosion layer, and in accordance with the provisions set aside for the pipe end 100-120mm in length. 8, grinding tube ends remain head tube with a wire brush on the left side header processing. Practice has proved that the long-term quality 3PE anti-corrosion steel with corrosion resistance. Anti-corrosion coating for corrosion protection is an economical, good anti-corrosion effect of measures in recent years, anti-corrosion steel pipe 3PE strengthen 3PE anti-corrosion steel grade are increasingly being applied to large pipeline projects. Every start is a large medium-range anti-corrosion steel pipe 3PE sales season.
