Product Description
Galvanized pipe, also known as galvanized steel pipe, is divided into hot-dip galvanized and electro-galvanized. The hot-dip galvanized layer is thick, the coating is uniform, the adhesion is strong, and the service life is long. The cost of electroplating is low, the surface is not smooth, and the corrosion resistance is worse than that of hot-dip galvanized pipe. Galvanized pipes include galvanized round pipes, galvanized square pipes, galvanized seamless pipes, galvanized welded pipes, etc.
In addition, there are cold-galvanized steel pipes, the zinc layer is very thin, it is easy to fall off, and the corrosion resistance is poor. So now cold galvanized steel pipes are banned as water supply pipes.

Application of galvanized steel pipe
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, and oil heaters and condensation pipes for chemical coking equipment. Pipes for coolers, coal distillation washing oil exchangers, trestle piles, and support pipes for mine tunnels, etc. Widely used in construction, machinery, coal mines, chemicals, electric power, railway vehicles, automobile industry, highways, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery, greenhouse construction and other manufacturing industries.
