Support any third-party testing or inspection







Hot dip galvanized steel pipes are widely used in manufacturing industries such as construction, machinery, coal mining, chemical industry, electric power, railway vehicles, automotive industry, highways, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, exploration machinery, and greenhouse construction.
Galvanized pipes have a wide range of applications. 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. They are also used as pipes for oil heaters, condenser coolers, coal distillation and washing oil exchangers in chemical coking equipment, as well as for support frames in bridge piles and mining tunnels.
