Epoxy Coated Steel Pipe - Inner Food-grade Epoxy Outer Polyethylene Powder | Exceptional Corrosion Resistance Smooth Inner Surface 50-year Lifespan

Supported by huge market experience we are the famous Manufacturer of Epoxy Coated Steel Pipe in Shijiazhuang Hebei China.
Inner epoxy outer polyethylene anti-corrosion steel pipe is a kind of coated steel pipe use the technique of internal spray epoxy powder outer shower coating with polyethylene powder. The intermediate frequency-heating mode utilizes the waste heat of the tube to cure both at the same time without separately coating the curing. Products inner coated with the food-grade epoxy making the inner surface of the pipe more smoothly not easy to breed microorganisms to ensured the water quality and increased the flow rate. Outer shower coating with polyethylene powder making the outer surface of plastic layer thickness increases corrosion resistance is more remarkable.
Pipeline characteristics:
1. The fungus and microorganism in the tap water or wastewater will not attach pipeline wall.
2. The inner coating of the pipeline is smooth; the fluid friction resistance is small.
3. The pipeline inner wall has excellent corrosion resistance.
4. The outer wall of the pipe coated with the single layer of polyethylene powder flexible resistant to bump with a strong resistance to soil corrosion green.
5. The design life of the inside and outside coating is up to 50 years.
