Tube For Plant Planting Tent Structure
Jun 28, 2017

1, hot-dip galvanized steel pipe structure: hot-dip galvanized pipe is to make the molten metal and iron-based body reaction to produce alloy layer, so that the matrix and the coating both. Tianjin Feilong Pipe Co., Ltd. supply of hot galvanized pipe is the first steel pipe pickling, in order to remove iron oxide on the surface of steel pipe, after pickling, through ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed water solution tank in the cleaning, and then into the hot dip bath. Hot-Dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. Hot-dip galvanized steel pipe substrate and molten plating liquid occur complex physical and chemical reaction, forming a corrosion-resistant structure of a dense zinc-iron alloy layer. The alloy layer is integrated with the pure zinc layer and the steel pipe matrix. So its corrosion resistance is strong.


2, Galvanized strip tube structure: galvanized strip tube to produce hot-dip galvanized pipe production process has been adjusted. In order to remove the iron oxide on the surface of the strip, the steel strip was pickled. Then dry and then make the tube. It has the advantages of uniform coating, light and little galvanization, which is lower than the cost of producing hot-dip galvanized pipe. Its corrosion resistance of the specific heat galvanized pipe slightly worse.
