Corrosion-resistant plastic-coated pipes are a composite structure featuring both internal and external plastic protective layers, with a middle layer of reinforced welded steel pipe or seamless pressure-bearing steel pipe.

Coating steel pipes are steel pipes that have undergone special processing, typically referring to pipes with a layer of plastic material applied to the inner or outer surface to enhance their corrosion resistance, wear resistance, and insulation properties. Coating steel pipes boast excellent corrosion resistance, capable of withstanding the erosion from acids, alkalis, salts, and other chemicals, making them suitable for various harsh environments. Additionally, they offer good wear and insulation properties, catering to different industry needs. During production, coating steel pipes must go through multiple processes, including pipe cleaning, surface treatment, and plastic coating. Strict quality control is required throughout these procedures to ensure the product's quality and performance.
