The production steps of galvanized steel pipe are as follows: First, the black parts are inspected to ensure that their quality meets the standards. Then, the parts are hung and degreased to remove the oil from the surface. Next, rinse and clean the surface of the part. After that, pickling is carried out to further clean the surface of the part. After cleaning again, the parts are immersed in flux to improve the welding effect. Next, the parts are dried with hot air to dry the surface. Then, hot galvanizing is carried out and the parts are immersed in molten zinc to form a galvanizing layer. Finally, cooling and passivation rinsing are carried out to make the galvanized layer more uniform and smooth. After all processes are completed, the parts are removed for inspection and repair. Finally, the qualified galvanized steel pipe is packaged, stored and transported.
Hot-dip galvanized steel pipe is widely used in construction, machinery, coal mine, chemical industry, electric power, railway vehicles, automobile industry, highways, Bridges, containers, sports facilities, agricultural machinery, petroleum machinery, exploration machinery and other manufacturing industries. Because of its excellent corrosion resistance, hot-dip galvanized steel pipe can maintain a long service life in a variety of harsh environments, so it has been widely used in many important fields.
Galvanized steel pipe is a welded steel pipe with a hot dip galvanized or electric galvanized layer on the surface. Galvanizing can increase the corrosion resistance of the steel pipe and extend the service life. Galvanized pipe has a wide range of uses. In addition to being used as pipelines for general low-pressure fluids such as water and gas, it is also used in the petroleum industry, especially oil well pipes and pipelines in offshore oil fields, oil heaters in chemical coking equipment, condensation cooling, etc. Septic tank pipe, coal rectification washing oil exchanger pipe, trestle pipe pile, mine tunnel support pipe, etc.
