[0002] Galvanized steel pipe is a welded steel pipe with hot-dip or electroplated zinc layer on the surface. Galvanizing can increase the corrosion resistance of steel pipes and extend their service life. Galvanized pipes are widely used. In addition to being used as pipeline pipes for general low-pressure fluids such as water, gas, and oil, they are also used as oil well pipes and oil pipelines in the petroleum industry, especially offshore oil fields, oil heaters, condenser coolers, coal distillation and washing oil exchangers for chemical coking equipment, as well as pier piles and support frames for mine tunnels. Hot-dip galvanized steel pipes are widely used in manufacturing industries such as construction, machinery, coal mines, chemicals, electricity, railway vehicles, automobile industry, roads, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, and prospecting machinery.
