Product Description ASTM Standard Low Carbon Hot Dip Galvanized Steel Welded Tube PipeIn order to improve the corrosion resistance of the steel pipe, the general steel pipe is galvanized, that is, galvanized steel pipe. Galvanized steel pipe is divided into hot dip galvanized and electric galvanized two, hot plating plating plating thick layer, low cost of electric galvanizing. The surface is not very smooth. Galvanized pipe specifications from 4 to 8 inches, commonly used DN to indicate its caliber.Hot-dip galvanized steel pipeComplex physical and chemical reactions occur between the steel tube substrate and the molten plating night, and a tight zinc-iron alloy layer with corrosion resistance is formed. The alloy layer is integrated with the pure zinc layer and the steel pipe matrix. Therefore, its corrosion resistance is strong.Cold galvanized steel pipeThe zinc layer is an electric coating, and the zinc layer is independently layered with the steel pipe matrix. The zinc layer is soft and thin, and the zinc layer is simply attached to the steel tube matrix and easy to fall off. Therefore, its corrosion resistance is poor. In new residential buildings, it is prohibited to use cold galvanized steel pipes as water supply.
