Galvanized steel pipe price
Galvanized steel pipes, also known as galvanized steel pipes, are divided into hot-dip galvanizing and galvanized two kinds. Hot-dip galvanized pipes have thick galvanized layer, uniform coating, strong adhesion and long service life. Zinc plating costs low, the surface is not very smooth, its corrosion resistance is much worse than that of hot dip galvanized pipe.
Hot-dip galvanized steel pipe is to make molten metal react with iron matrix to produce alloy layer, so that the matrix and coating can be combined. Hot-dip galvanizing is a process of pickling steel pipes. In order to remove iron oxide from the surface of steel pipes, after the process of pickling, the pipes are cleaned by ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank, and then will be sent into the hot-dip galvanizing tank. Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life etc..
Hot-dip galvanized steel pipes are widely used in the filed of construction, machinery, coal mine, chemical industry, electric power, railway vehicles, automobile industry, highway, bridge, container, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery and other manufacturing industries.
The connection way of galvanized steel pipe can be divided into two aspects: screw thread and welding.
Weight factor of galvanized steel pipes:
1)Nominal wall thickness (mm): 2, 2.5, 2.8, 3.2, 3.5, 3.8, 4, 4.5.
2)Coefficient parameters (c): 1.064, 1.051, 1.045, 1.040, 1.036, 1.034, 1.032, 1.028.
3)Steel grades: Q215A; Q215B; Q235A; Q235B.
