Anti-corrosion steel pipe plays important roles in the current engineering service, such as the 3PE anti-corrosive pipe. It has good corrosion resistance, low water absorption, high mechanical strength properties.
It is suitable for the water supply and drainage, positive and negative pressure ventilation, fire sprinkler pipe network, gas supply engineering, underground water pipeline and oil pipeline.2.The brief introduction of 3PE Coating Steel PIPE
External Polyethylene Coating for Pipe This Standard covers the following coating systems: (a) System A1: a coating that consists of an adhesive and a polyethylene outer sheath; (b) System A2: a coating that consists of an adhesive and a polyethylene outer sheath that has more stringent peel adhesion requirements than those for System A1; (c) System B1: a coating that consists of a liquid or powdered epoxy primer, a polymeric adhesive, and polyethylene outer sheath; and (d) System B2: a coating that consists of a powdered epoxy primer, a powdered copolymer adhesive,and a powdered polyethylene outer layer.
