Overview, plastic coated steel pipe, also known as plastic coated pipe, steel-plastic composite pipe, plastic coated composite steel pipe, is based on steel pipe, through the spray, rolling, dip, suction process on the inner surface of the steel pipe (bottom pipe) welding a layer of plastic anti-corrosion A steel-plastic composite steel pipe with a plastic anti-corrosion layer welded to the inner or outer surface.
Product features: Plastic coated steel pipe is made of PE (modified polyethylene) for hot dip coating or EP (epoxy resin) for internal and external coating, with excellent corrosion resistance. At the same time, the coating itself has good electrical insulation and does not cause electrical corrosion. Low water absorption, high mechanical strength, and low friction coefficient can achieve long-term use. It can also effectively prevent the damage of plant roots and soil environmental stress. Easy to connect and easy to maintain.
Polyethylene coated steel pipes have obvious advantages over ordinary steel pipes:
1. Adapt to buried and humid environments, and can withstand high temperatures and extremely low temperatures.
2. Strong anti-interference ability. If the plastic coated steel pipe is used as a cable sleeve, it can effectively shield the external signal interference.
3. Withstand the pressure strength, the maximum pressure can reach 6Mpa.
4. The insulation performance is good, and the leakage protection of the wire will never occur.
5. No burrs, smooth pipe wall, suitable for wearing wires or cables when construction.
Plastic coated steel pipe application field
1. Various forms of circulating water system (civil circulating water, industrial circulating water), excellent performance, anti-corrosion period of up to 50 years.
2. Fire water supply system.
3. Water supply and drainage transportation of each building (especially suitable for cold and hot water systems in hotels, hotels, high-end residential areas).
4. Various chemical fluid transport (corrosion resistance to acid, alkali and salt).
5. Ground pipe and passage pipe of wire and cable.
6. Ventilation pipes, supply and drainage pipes of mines and mines.
