Coated steel pipe, also known as coated pipe or steel plastic composite pipe, is made of steel pipe as the substrate and welded with a plastic anti-corrosion layer through a specific process. It has excellent corrosion resistance and low frictional resistance, suitable for conveying various media. We offer a variety of colors, coating thicknesses, and coating methods, with diverse specifications to adapt to a wide range of environmental temperatures. There are various connection methods, with good electrical insulation, low water absorption, high mechanical strength, and can be used for a long time.

Coated steel pipe, also known as coated pipe, steel plastic composite pipe, or coated composite steel pipe, is a steel plastic composite steel pipe that uses a steel pipe as the substrate and fuses a plastic anti-corrosion layer on the inner surface of the steel pipe (bottom pipe) or on the inner and outer surfaces through spraying, rolling, immersion, and suction processes. Coated steel pipes have excellent corrosion resistance and relatively low friction resistance. Epoxy resin coated steel pipes are suitable for transporting media such as water supply and drainage, seawater, warm water, oil, and gas, while polyvinyl chloride coated steel pipes are suitable for transporting media such as drainage, seawater, oil, and gas.

Common colors: black, gray, blue, red, white, green;

Coating thickness: PE (modified polyethylene) coating thickness is 400um-1000um, EP (epoxy resin) spraying thickness is 100um-400um;

Coating method: PE (polyethylene) is hot-dip molded EP, (epoxy resin) is sprayed inside and outside;

Product specifications: DN15-DN1660;

Environmental temperature: -30 ℃ to 120 ℃;

Connection methods: threaded (DN15-DN100), groove (DN65-DN400), flange (applicable to any diameter), welded, bimetallic connection, socket, pipe joint, sealed connection, etc.

Coated steel pipes are products that use PE (modified polyethylene) for hot-dip molding or EP (epoxy resin) for internal and external coating, and have excellent corrosion resistance. At the same time, the coating itself also has good electrical insulation and will not produce electrical corrosion. Low water absorption rate, high mechanical strength, low friction coefficient, capable of achieving long-term use.
