Product Description
Galvanized pipes, also known as galvanized steel pipes, are divided into hot dip galvanized and electro-galvanized. The hot-dip galvanizing 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 pipes. Galvanized pipes include galvanized round pipes, galvanized square pipes, galvanized seamless pipes, galvanized welded pipes, etc. Generally, galvanized steel pipes are seamed steel pipes. Seamless steel pipes are galvanized only on special request.
Galvanized square tube is divided into hot-dip galvanized square tube and cold-dip galvanized square tube from the production process. This square tube is based on a square tube formed by placing the square tube in a hot-dip galvanizing bath after a series of chemical reactions. The cold-galvanized square tube uses the principle of cold-galvanizing on the square tube used to make the square tube anti-corrosion.

Applications
Hot-dip galvanized steel pipes are 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.
Galvanized steel pipe is a welded steel pipe with a hot-dip galvanized or electro-galvanized layer on the surface. Galvanizing can increase the corrosion resistance of steel pipes and prolong the 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 pipes in the petroleum industry, especially in offshore oil fields, and oil heaters and condensers in chemical coking equipment. Pipes for coolers, coal distillation washing oil exchangers, and pipes for trestle piles, supporting frames for mine tunnels, etc.
