Corrosion-proof plastic-coated pipes are composite structures featuring both internal and external plastic protective layers, with a reinforced welded steel pipe or seamless pressure-bearing steel pipe in the middle.

Fusion bonded epoxy (FBE) coated steel pipes are steel pipes that have been processed through a special technique, 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 insulation 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, FBE coated steel pipes offer good wear and insulation properties to meet the demands of different industries. During production, the pipes undergo multiple processes, including pipe cleaning, surface treatment, and plastic coating. Each of these steps requires stringent quality control to ensure the product's quality and performance.
