Product Description

Product Description

In recent years, the production of galvanized sheet in China has increased year by year, while the import volume is also increasing year by year, and the growth rate is even higher than that of production; At the same time, the production of carbon Steel Plate, carbon Steel Coil, galvanized coil, color coated coil, Carbon Steel Pipe, galvanized pipe and other products is also increasing year by year, and the steel market can be expected in the future.

DN15 DN20 DN25 Galvanized Steel Pipe: in order to improve the corrosion resistance of Steel Pipe, general steel pipe is galvanized. Galvanized Steel Pipes are divided into hot-dip galvanizing and electro galvanizing. DN15 DN20 DN25 Galvanized Steel Pipe layer is thick, the cost of electro galvanizing is low, and the surface is not very smooth.

DN15 DN20 DN25 Galvanized Steel Pipe is to make molten metal react with iron matrix to produce alloy layer, so as to combine the matrix and coating. DN15 DN20 DN25 Galvanized Steel Pipe is to pickle the steel pipe first. In order to remove iron oxide on the surface of the steel pipe, after pickling, it is cleaned in ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank, and then sent to the hot dip galvanizing tank. DN15 DN20 DN25 Galvanized Steel Pipe has the advantages of uniform coating, strong adhesion and long service life. The matrix of DN15 DN20 DN25 Galvanized Steel Pipe has complex physical and chemical reactions with the molten plating solution to form a corrosion-resistant zinc ferroalloy layer with compact structure. The alloy layer is integrated with pure zinc layer and steel pipe matrix, so it has strong corrosion resistance.
