Hot Galvanized Steel Pipe Construction Is Also More Convenient
Oct 26, 2017

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, long life and other advantages. 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. Hot-dipped Galvanzied Steel Pipe So its strong corrosion resistance. 1, uniformity of the galvanized layer: steel pipe sample in the copper sulfate solution for 5 times can not be red (copper) 2, the surface quality: galvanized steel pipe surface should be a complete galvanized layer, Plated spots and bubbles present, allowing for the presence of small rough surfaces and local zinc tumors. 3, galvanized layer Weight: According to the demand side, galvanized steel pipe can be used for zinc layer weight determination, the average should not be less than 500g / square meter, Hot-dipped Galvanzied Steel Pipe any sample shall not be less than 480g / square meter.

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-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, Hot-dipped Galvanzied Steel Pipe not too fast oxidation, 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, 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!

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.
