The production process of galvanized welded steel pipe is a coating welding process, that is, hot-dip galvanizing and hot-rolled steel sheets, and then galvanized steel coils are used to cut galvanized steel strips into high-frequency welded tubes. The outside of the weld is sprayed with zinc spray equipment, and there is no need to process the weld, which meets the national standard galvanized pipe. The serious environmental pollution in the pickling process of the invention is eliminated, the production process is simplified, the surface of the product is smooth, the galvanization is uniform, and the consumption of zinc is reduced.
The production process of galvanized welded steel pipe is a low-pressure fluid, which is characterized in that the hot-rolled steel plate is first galvanized, then the galvanized strip is cut into a tubular shape, and zinc is sprayed on the outside of the weld by a zinc spraying device.
