Galvanized Steel Pipes are divided into cold galvanized steel pipes and hot galvanized steel pipes. Cold galvanized steel pipes have been banned, and the latter has been temporarily promoted by the state for use. In the 1960s and 1970s, developed countries internationally began to develop new types of pipes and gradually banned Galvanized Pipes. Hot dip galvanized steel pipes are widely used in fire protection, electricity, and highways. Hot dip galvanized steel pipes are widely used in manufacturing industries such as construction, machinery, coal mines, chemicals, electricity, railway vehicles, automotive industry, highways, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, exploration machinery, and greenhouse construction. Welded steel pipes with hot-dip or electro galvanized coatings on the surface of galvanized steel pipes. Galvanizing can increase the corrosion resistance of steel pipes and extend their service life. Galvanized pipes have a wide range of uses, 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 delivery pipes in the petroleum industry, especially in offshore oil fields, as well as pipes for oil heaters, condensate coolers, coal distillation and washing oil exchangers in chemical coking equipment, as well as pipes for support frames in trestle piles and mining tunnels.
