Plastic-lined pipes are based on ordinary carbon steel pipes, lined with heat-resistant engineering plastics of excellent chemical stability. They are either cold-drawn and compounded or formed by rotational molding. These pipes combine the mechanical properties of steel pipes with the corrosion resistance, slow scaling, and reduced microbial growth of engineering plastics, making them ideal for conveying acidic, alkaline, saline, corrosive gases, and other media. Lined with food-grade polypropylene, they are suitable for food and drinking water industries. Common types of plastic-lined pipes include: steel-lined polypropylene pipes (GSF.PP), steel-lined polyvinyl chloride pipes (GSF.PVC), steel-lined polyethylene pipes (GSF.PE), and steel-lined polyolefin pipes (GSF.PO).

特点 of Plastic Coated Pipe:
