PRODUCT DESCRIPTION
Hot-dip galvanized steel pipe is a steel pipe that is coated with a layer of zinc on the surface of the steel pipe to improve its corrosion resistance. Hot-dip galvanized steel pipe is formed by immersing the steel pipe in molten zinc liquid to attach a layer of zinc to the surface, thereby forming a corrosion-resistant protective layer. The hot-dip galvanizing process not only improves the corrosion resistance of the steel pipe, but also extends its service life. Galvanized steel pipe is widely used in the fields of construction, machinery, automobiles, aerospace, etc., especially in fire protection, electricity and highways.
Galvanized pipes have strong corrosion resistance, high durability, excellent conductivity and great structural strength. Galvanized pipes are effectively isolated from direct contact between the steel pipe and the corrosive medium by galvanizing the surface of the steel pipe, thereby greatly improving the corrosion resistance of the pipe and enabling it to maintain stable performance in humid and corrosive environments. The protection of the galvanized layer makes the service life of the galvanized pipe relatively long, and it can maintain a service life of decades under normal conditions of use, reducing the trouble and cost of frequent replacement of pipes. In addition, galvanized pipes also have good electrical conductivity and are suitable for occasions where electrical conductivity is required.
Galvanized steel pipes have good corrosion resistance, and the zinc coating on their surface can effectively extend their service life. The product has stable quality, firm welding, smooth surface, and is suitable for a variety of complex environments. The galvanizing process is divided into hot-dip galvanizing and electro-galvanizing, and the process selection is flexible to meet different needs.
As a multi-purpose pipe, galvanized steel pipes can not only be used for the transportation of low-pressure fluids, but also perform well in the fields of petroleum, chemical industry, coal, marine engineering, etc. It is suitable for a variety of equipment and scenarios such as oil well pipes, oil pipelines, heaters, condensers, etc., and is widely used in infrastructure construction such as trestle pipe piles and mine tunnel support frames, showing excellent strength and durability, and strong reliability.
Hot-dip galvanized steel pipes are widely used in manufacturing industries such as construction, machinery, coal mining, chemical industry, electric power, railway vehicles, automobile industry, roads, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery, greenhouse construction, etc.
