Hot-dip Galvanized Steel Pipe Has The Characteristic Of Anticorrosion And Wear-resisting
Sep 20, 2017

Hot galvanized steel pipe is widely used in construction, machinery, coal, chemical, railway vehicles, automobile industry, highway, bridge, container, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery and other manufacturing industries.

The hot-dip galvanized steel pipe is a reaction between the molten metal and the iron matrix to produce an alloy layer, so that both the substrate and the coating are combined. Hot-dip galvanizing is the first pickling of the steel pipe, in order to remove the iron oxide surface of the steel pipe, pickled, Hot-dipped Galvanzied Steel Pipe through ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed water tank cleaning, and then sent Hot dip bath. Hot galvanized with uniform coating, strong adhesion, Hot-dipped Galvanzied Steel Pipe long life and other advantages. Hot-dip galvanized steel pipe matrix and molten bath complex physical and chemical reactions, the formation of corrosion-resistant structure of a dense zinc alloy layer. Alloy layer and pure zinc layer, steel pipe body integration. So its strong corrosion resistance.

Hot-dip galvanized steel pipe is the acid pickling, remove the surface of the oxide layer, and then in the zinc chloride aqueous solution for cleaning, after the steel pipe into the hot plating tank, and then heated, Hot-dipped Galvanzied Steel Pipe hot-dip galvanized steel pipe formed. Through such a process, so that hot-dip galvanized steel pipe has the following advantages:

First, the use of anti-embroidered steel pipe surface more durable, not too fast oxidation, Hot-dipped Galvanzied Steel Pipe not in the formation of white rust on the steel pipe;

Second, the full protection of the steel pipe, through the heating of each part of the steel pipe are plated with zinc, bumps have been protected;

Third, with anti-corrosion characteristics of wear and tear, Hot-dipped Galvanzied Steel Pipe so that the use of steel pipe longer

Four, because already in the steel pipe has been plated outside the zinc, which eliminates the need for oil or paint outside the time, Hot-dipped Galvanzied Steel Pipe the construction is more convenient;

5, galvanized steel pipe is three or nine days will not crack, especially for the cold weather in the north!
