Mining coated spiral welded pipes have the characteristics of corrosion resistance and relatively low friction resistance, making them particularly suitable for transporting media such as water supply and drainage, seawater, warm water, oil, and gas.

　　
When selecting a product, the first step is to inspect the coating. The appearance of the product is aesthetically pleasing and leaves a clear impression on people. In addition to checking the smoothness of the coating, it is also necessary to check whether there are any bubbles or bumps in the coating. Secondly, the measurement of coating thickness requires the use of specialized measuring instruments.

The epoxy resin coating inside and outside the steel pipe is made of EP powder melted at high temperature to the inner and outer walls of the steel pipe, forming a plastic protective film. It has the corrosion resistance and electrical insulation properties of plastic, as well as the mechanical strength of steel pipes, which can achieve the goal of long-term use without corrosion.
