Coated steel pipe

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.

Product characteristics
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. It can also effectively prevent damage to plant roots and soil environmental stress. Convenient connection and easy maintenance
Advantage
1. Adapt to buried and humid environments, and can withstand high and extremely low temperatures.
2. Strong anti-interference ability. If plastic coated steel pipes are used as cable conduits, they can effectively shield external signal interference.
3. It has good compressive strength, with a maximum pressure of up to 6Mpa.
4. Good insulation performance, as a protective tube for wires, it will never experience leakage.
5. No burrs, smooth pipe wall, suitable for threading wires or cables during construction.
