No, steel-plastic composite pipe is a new pipeline material developed in recent years. It is composed of seamless steel pipe, welded steel pipe and galvanized steel pipe as matrix, plus various types of plastics (such as epoxy resin and polyethylene). Steel-plastic composite pipe is composed of metal thin-walled pipe lined with engineering plastic pipe, and the lining pipe is made of UHMW PE. Steel-plastic composite pipe is hygienic and non-toxic, and has excellent low temperature resistance; Steel-plastic composite pipe is wear-resistant and does not scale.

At present, steel-plastic composite pipe is relatively mature and has been widely used in petroleum, chemical industry, construction, shipbuilding, communication, electric power, underground gas pipeline and other fields. It is a better product to replace the traditional galvanized pipe at present, and is known as green and environmentally friendly pipe.
