Corrosion-resistant plastic-coated pipes are a composite structure that features both internal and external plastic protective layers, with the middle section being either a reinforced welded steel pipe or a seamless pressure steel pipe.

Fusion bonded pipe is a steel pipe that has been processed through a special technique, typically involving the application of a plastic coating to either the inner or outer surface of the pipe to enhance its corrosion resistance, wear resistance, and insulating properties. The characteristics of fusion bonded pipe include excellent corrosion resistance, capable of withstanding the erosion from acids, alkalis, salts, and other chemicals, making it suitable for a variety of harsh environments. Additionally, it boasts good wear and insulating properties to meet the demands of different fields. During production, fusion bonded pipe undergoes multiple processes such as pipe cleaning, surface treatment, and plastic coating, all of which require stringent quality control to ensure product quality and performance.
