What are the characteristics and advantages of plastic-coated steel pipes

First, what are the characteristics of plastic-coated steel pipes?
Plastic-coated steel pipes are products made by hot-dip plastic coating with PE (modified polyethylene) or internal and external coating with EP (epoxy resin), possessing excellent corrosion resistance. Simultaneously, the coating itself has good electrical insulation properties, preventing electrolytic corrosion. With low water absorption, high mechanical strength, and a low coefficient of friction, plastic-coated steel pipes can achieve long-term use. They also effectively prevent damage from plant roots and soil environmental stress. Connections are convenient, and maintenance is simple.

Second, what are the advantages of plastic-coated steel pipes?
1. Plastic-coated steel pipes are suitable for buried and humid environments and can withstand high and extremely low temperatures.
2. Plastic-coated steel pipes have strong anti-interference capabilities. If used as cable conduits, they can effectively shield external signal interference.
3. Plastic-coated steel pipes have good pressure resistance, with pressures up to 6 MPa.
4. Plastic-coated steel pipes have excellent insulation properties, ensuring they will never leak electricity when used as protective conduits for electrical wires.
5. Plastic-coated steel pipes are burr-free and have smooth walls, making them suitable for threading electrical wires or cables during construction.
