| Galvanized steel tubes welded with hot dip or electrogalvanized coating on the surface. Galvanizing can increase the corrosion resistance of steel pipes 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 to make molten metal and iron matrix reaction to produce an alloy layer, so that the matrix and coating are combined. Hot dip galvanized steel pipe is first pickling, in order to remove iron oxide on the surface of the steel pipe, after pickling, through ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank for cleaning, and then into the hot dip plating tank. Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. Hot dip galvanized steel tube matrix and molten bath have complex physical and chemical reactions, forming corrosion resistant structure of tight zinc-iron alloy layer. The alloy layer is integrated with pure zinc layer and steel tube matrix, so it has strong corrosion resistance. Cleaning method 1. Firstly, use solvent to clean the steel surface and remove the organic matter on the surface. 2, then use tools to remove rust (wire brush), remove loose or inclined scale, rust, welding slag, etc., 3, the use of pickling. Galvanized is divided into hot plating and cold plating, hot plating is not easy to rust, cold plating is easier to rust. Hot dip galvanized steel pipe is widely used in construction, machinery, coal mine, chemical industry, electric power, railway vehicles, automobile industry, highway, bridge, container, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery, greenhouse construction and other manufacturing industries.
