Product Description
(1) spangle coating of normal zinc coating
During the normal solidification process of zinc layer, zinc grains grow freely to form a coating with obvious zinc flower morphology.
(2) ShellShellSpangle coating of small zinc flowers
During the solidification process of zinc layer, the zinc grains are artificially limited to form as fine zinc flower coating as possible.
(3) Zinc free coating spangle-free
By adjusting the chemical composition of the bath, the coating does not have visible zinc flower morphology, uniform surface.
Hot-dip galvanized steel pipe is widely used in construction, machinery, coal mine, chemical industry, electric power, railway vehicles, automobile industry, highways, Bridges, containers, sports facilities, agricultural machinery, petroleum machinery, mining machinery, greenhouse construction and other manufacturing industries.Galvanized steel pipe Welded steel pipe with a hot dip or galvanizing coating. Galvanizing can increase the corrosion resistance of steel pipe and prolong the service life. Galvanized pipe USES is very wide, in addition to a general low pressure fluid such as water, gas, oil line pipe, also used as oil industry, especially the ocean oil field oil well pipe, oil pipe, chemical coking equipment of oil heater, the condensing, exchange of coal distillation wash oil cooler for tube, and trestle pile, mining tunnel supporting frame tube, etc.

Hot dip galvanized pipe is made of molten metal and iron matrix reaction to produce alloy layer, so that the matrix and coating two combination. Hot dip galvanizing is to first pickling the steel tube. In order to remove the iron oxide on the surface of the steel tube, after pickling, it is cleaned in the tank of ammonium chloride or zinc chloride solution or mixed aqueous solution of ammonium chloride and zinc chloride, and then sent into the hot dip plating tank. Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. Complex physical and chemical reactions occur between the matrix of hot-dip galvanized steel pipe and the molten bath to form a compact zinc-iron alloy layer with corrosion resistance. The alloy layer is integrated with pure zinc layer and steel tube matrix, so its corrosion resistance is strong.
Galvanized steel pipe connection: thread, welding.
Connect in a rolling groove
Welded type connection
Wire type connection
