Hot Galvanized Steel Pipe With Anti-embroidered Treatment
Aug 09, 2017


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

First, the hot galvanized steel pipe surface with anti-embroidered treatment more durable, not too fast oxidation, not in the hot galvanized steel pipe above the formation of white rust;

Second, the hot galvanized steel pipe to conduct a comprehensive protection, Hot-dipped Galvanzied Steel Pipe after heating so that each part of the hot-dip galvanized steel are plated with zinc, Hot-dipped Galvanzied Steel Pipe bumps have been protected;

Third, with anti-corrosion characteristics of wear and tear, so that hot-dip galvanized steel pipe longer use

Four, because already in the hot galvanized 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, hot-dip 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, Hot-dipped Galvanzied Steel Pipe 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, Hot-dipped Galvanzied Steel Pipe so that both the substrate and the coating are combined. Hot-dip galvanizing is the first hot-dip galvanized steel pipe for pickling, in order to remove hot-dip galvanized steel pipe surface of iron oxide, pickled, through ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed water tank And then washed into a hot dip bath. Hot galvanized with uniform coating, strong adhesion, Jun Cheng pipeline 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 close zinc alloy layer. Alloy layer and pure zinc layer, hot-dip galvanized steel pipe into one body. Hot-dipped Galvanzied Steel Pipe So its strong corrosion resistance. Cold galvanized galvanized, galvanized little, only 10-50g / m2, its own corrosion resistance than hot galvanized pipe a lot worse. Regular galvanized pipe manufacturers, in order to ensure quality, most do not use electro-galvanized (cold plating). Only those small size, old equipment, Hot-dipped Galvanzied Steel Pipe small businesses using galvanized, of course, their prices are relatively cheap. The current Ministry of Construction has officially below, out of the cold behind the cold galvanized pipe, the future is not allowed to use cold galvanized pipe for water, gas pipe. Hot-dipped Galvanzied Steel Pipe The zinc layer is an electroplated layer, and the zinc layer is independently layered with the hot-dip galvanized steel pipe matrix. Zinc layer is thin, zinc layer is simply attached to the hot-dip galvanized steel pipe matrix, easy to fall off. So its poor corrosion resistance. In the new residential, the use of cold galvanized hot-dip galvanized steel pipe as a water supply pipe.
