What can be considered a “high-quality” plastic-coated steel pipe

Plastic-coated steel pipes have the dual advantages of steel pipes and plastic pipes. They have the mechanical strength and bearing pressure of steel pipes, and the smoothness, wear resistance, corrosion resistance, low water flow resistance, and environmental protection of the inner wall of non-metallic pipes. With the progressive development of my country’s pipe industry, various plastic-coated steel pipes of varying quality have appeared on the market. So what kind of plastic-coated steel pipe can be called “high-quality”?

1. Double-layer coating. Double-layer coating refers to a composite coating structure, with an anti-corrosion coating at the bottom layer and an anti-mechanical damage coating at the surface layer. Although the material types are the same, the material properties are very different. Double-layer coating exerts the characteristics of the material to make the function more perfect.

2. Touch, smell, and pinch. Touch the texture: coarse particles are likely to be mixed with impurities; smell the smell: the main material of plastic-coated steel pipe is polypropylene, and good pipes have no smell; pinch hardness: the hardness of plastic-coated steel pipes is good, and they will not be deformed by pinching them casually.

3. For plastic-coated steel pipes, water supply and drainage professionals, often only care about the application of pipes without asking other questions. The problem of plastic-coated steel pipes is not entirely about producing qualified products. In addition, there are service issues, such as repairing and re-coating plastic-coated steel pipes.

Finally, price advantage. In the current pipe market, price advantage is a strong market competitiveness, even higher than quality. The price of plastic-coated steel pipes can be on par with galvanized steel pipes. Only with good price and quality can the market share be improved.
