Galvanized pipe is made of molten metal and iron matrix reaction to produce alloy layer, so that the matrix and coating two combination. galvanizing is to first pickling the steel tube. In order to remove the iron oxide on the surface of the steel tube, after pickling, it is cleaned in the tank of ammonium chloride or zinc chloride 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 steel tube base 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. Therefore, its corrosion resistance is strong.

The alloy layer is integrated with the pure zinc layer and the steel tube matrix. Therefore, its corrosion resistance is strong.
Galvanized steel pipe is a steel pipe that has been coated with a protective layer of zinc to prevent corrosion. The galvanizing process involves dipping steel pipe into molten zinc, which bonds with the steel surface to form a durable, corrosion-resistant layer.
Galvanized steel pipe offers several advantages over other types of steel pipe, including:
1) Corrosion Resistance: The galvanized layer protects the steel pipe from rust and corrosion, making it suitable for harsh environments or applications exposed to moisture or chemicals.
2) Strength and Durability: Galvanized steel pipe is strong and durable enough to withstand heavy loads and extreme temperatures.
3) Cost-effective: Galvanized steel pipe is relatively inexpensive compared to other corrosion-resistant materials, making it a cost-effective choice for many applications.
4) Low maintenance: Galvanized steel pipe requires minimal maintenance and can last for many years if cared for properly.
5) Versatility: Galvanized steel pipe can be used in a variety of applications including construction, fabrication and transportation.
Overall, galvanized steel pipe is a reliable and cost-effective choice for many applicat
