Large-diameter plastic-coated steel pipes, as the name suggests, are plastic-coated steel pipes with relatively large pipe diameters. Large-diameter plastic-coated steel pipes are mainly used in municipal and major building water supply and drainage. Large-diameter plastic-coated steel pipes can be used in different fields, mainly because of it. Product performance.

Large-caliber plastic-coated steel pipes, the outer wall of the product is coated with high-adhesion, impact resistance, anti-corrosion and weather-resistant thermosetting powder coatings, and the inner wall is coated with high-adhesion, anti-corrosion thermoplastic powder coatings. It is made by sandblasting chemical double pretreatment, preheating, internal coating, external coating, curing, post-treatment and other processes.

The biggest feature of large-caliber plastic-coated steel pipe is that the pipe wall is smooth and clean, the drainage performance is good, the fluid resistance is small, and it does not scale. The linear expansion coefficient of the large-diameter plastic-coated pipe is very small, and it is used in the main water pipe
