Technical Field

[0001] The utility model relates to the technical field of galvanized pipe processing, in particular to a galvanized pipe cutting device. Background Art

[0002] 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 still advocated by the country for temporary use. In the 1960s and 1970s, developed countries in the world began to develop new pipes and banned galvanized pipes one after another. The Ministry of Construction of China and other four ministries also issued a document to ban galvanized pipes as water supply pipes from 2000. Galvanized pipes are rarely used for cold water pipes in newly built communities. Some communities use galvanized pipes for hot water pipes. Hot-dip galvanized steel pipes are widely used in fire protection, electricity and highways. When processing galvanized pipes, cutting devices are required to cut them;
