Plastic coated spiral pipe for water supply and drainageAlso known as plastic coated pipe, steel plastic composite pipe, or plastic coated composite steel pipe, it is a steel plastic composite steel pipe that uses a steel pipe as the substrate and fuses a layer of plastic anti-corrosion coating 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 spiral 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 for coated spiral steel pipes: black, gray, blue, red, white, green

Coating thickness of spiral steel pipe coated with plastic: 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

Coated spiral steel pipe product specifications: DN15-DN1660 Environmental temperature: -30 ℃ to 120 ℃

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

Coated spiral steel pipe is a product that uses PE (modified polyethylene) for hot-dip molding or EP (epoxy resin) for internal and external coating, and has 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. It can also effectively prevent damage to plant roots and soil environmental stress. Convenient connection and easy maintenance.
