Galvanized steel pipes are divided into cold galvanized steel pipes and hot galvanized steel pipes.
Hot dip Galvanized Pipe is made of molten metal and iron matrix reaction to produce alloy layer, so that the matrix and the coating of the two combination. Hot dip galvanizing is to first pickling the Steel Pipe. In order to remove the iron oxide on the surface of the steel pipe, after pickling, it is cleaned by ammonium chloride or zinc chloride aqueous 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 the pure zinc layer and the steel tube matrix, so its corrosion resistance is strong.
Cold galvanized pipe is electric galvanized, galvanized amount is very small, only 10-50g/m2.

Product Show
Welded steel tubes with hot dip or electrogalvanizing coating. Galvanizing can increase the corrosion resistance of steel pipe and prolong its 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.
The zinc layer is an electroplating layer, which is separated from the steel pipe substrate. The zinc layer is thin, which is simply attached to the steel pipe substrate and easy to fall off. Therefore, its corrosion resistance is poor. It is prohibited to use cold galvanized steel pipes as water supply pipes in new residential buildings.
