Advantages of internal and external plastic coated steel pipes

1. The internal and external plastic-coated steel pipes have high mechanical strength and are suitable for harsh usage environments;
2. The inner and outer coatings of the plastic-coated steel pipe can prevent metal oxidation and have good chemical corrosion resistance;
3. The coating of the internal and external plastic-coated steel pipe has strong adhesion, high bonding strength, and good impact resistance;
4. The inner and outer plastic-coated steel pipe has a low roughness coefficient and friction coefficient, and has excellent resistance to foreign matter adhesion;
5. The plastic-coated steel pipes inside and outside are anti-aging and have a long service life, especially suitable for underground water transportation.
