Selection of epoxy resin composite steel pipe

Epoxy composite steel pipe is based on steel pipe, plastic powder is used as the coating material, and a plastic layer is melt-coated on its inner surface, and a plastic layer or other anticorrosive layer is melt-coated on its outer surface. Steel-plastic composite products. Plastic-coated steel pipes are divided into polyethylene-coated steel pipes and epoxy-coated steel pipes according to different inner coating materials. The product mark consists of the code of the plastic-coated composite steel pipe, the code of the inner coating material and the nominal size. The water-supply lining plastic composite steel pipe is on the inner wall of the steel pipe, and is lined with plastic ethylene (PE), heat-resistant polyethylene (PE-RT), cross-linked polyethylene (PE-X), and polypropylene (PP-R) according to the requirements of the conveying medium. , Hard polyvinyl chloride (PVC-U), chlorinated polyvinyl chloride (PVC-C) and other thermoplastic pipes. Due to the improvement of the process, some products have added an outer plastic layer. The products are classified into plastic-lined steel pipes for cold water and plastic-lined steel pipes for hot water according to the temperature of the conveyed water. The product mark consists of the code of the plastic-lined steel pipe, the code of the plastic-lined material, and the nominal diameter.
