The Carbon Steel-Plastic Lined Pipe is a composite pipe with a carbon steel seamless or welded pipe as the base, lined with high-performance engineering plastics (e.g., PO, PP, PTFE). It perfectly combines the superior mechanical strength of carbon steel with the top-tier chemical corrosion resistance of engineering plastics, serving as an industrial-grade core piping material for conveying corrosive and abrasive media in chemical, power, and mining industries.
