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

Fusion bonded pipe is a steel pipe that has undergone special processing, typically referring to pipes where a layer of plastic material is coated on the inner or outer wall 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 of acids, alkalis, salts, and other chemical substances, making it suitable for various harsh environments. Additionally, it boasts good wear resistance and insulating properties to meet the demands of different fields. During production, fusion bonded pipe goes through multiple processes such as pipe cleaning, surface treatment, and plastic coating, all of which require rigorous quality control to ensure product quality and performance.
