The difference between plastic coated steel pipe and galvanized steel pipe

Plastic coated steel pipes, also known as plastic-coated pipes, steel-plastic composite pipes, and plastic-coated composite steel pipes, use steel pipes as the substrate, and weld a layer of plastic anti-corrosion layer or Steel-plastic composite steel pipe with plastic anti-corrosion layer welded on the inner and outer surfaces.

Galvanized steel pipes are divided into cold-galvanized steel pipes and hot-dip galvanized steel pipes. Cold-galvanized steel pipes have been banned, and the latter has been advocated by the state to be used temporarily. In the 1960s and 1970s, developed countries in the world began to develop new pipes and gradually banned galvanized pipes. Four ministries and commissions, including the Ministry of Construction of China, has also issued a document stating that galvanized pipes should not be used as water supply pipes 2000. Galvanized pipes are rarely used for cold water pipes in newly built communities, and galvanized pipes are used for hot water pipes in some communities. Hot-dip galvanized steel pipes are widely used in fire protection, electric power, and highways.
