Product Description
Galvanized steel pipes are divided into cold-dip galvanized steel pipes and hot-dip galvanized steel pipes. Cold-dip galvanized steel pipes have been banned, and the latter is also temporarily advocated by the state. In the 1960s and 1970s, developed countries in the world began to develop new pipes and gradually banned galvanized pipes. my country’s Ministry of Construction and other four ministries also issued a document to ban the use of galvanized pipes as water supply pipes from 2000. Galvanized pipes are rarely used in cold water pipes in newly built communities, and some communities also use galvanized pipes for hot water pipes. Hot-dip galvanized steel pipes are widely used in fire protection, electricity, highways and other fields.
