Corrosion-resistant plastic-coated pipes are composite structures with both internal and external plastic protective layers, with the middle part consisting of reinforced welded steel pipes or seamless pressure-bearing steel pipes.

Fusion-bonded polyethylene coated steel pipes are steel pipes that have undergone special processing, typically involving the application of a plastic coating to the inner or outer surface of the pipe to enhance its corrosion resistance, wear resistance, and insulating properties. These pipes are characterized by their excellent corrosion resistance, capable of withstanding the erosion from acids, alkalis, salts, and other chemicals, making them suitable for various harsh environments. Additionally, they possess good wear and insulating properties to meet the demands of different fields. During production, the pipes must undergo multiple processes, including cleaning, surface treatment, and plastic coating, all of which require strict quality control to ensure product quality and performance.
