Classification Of Galvanized Pipes

Galvanized pipe, also known as galvanized steel pipe, is divided into hot dip galvanized and electric galvanized. Hot dip galvanizing layer thick, uniform coating, strong adhesion, long service life. Electroplating cost is low, the surface is not smooth, corrosion resistance than hot dip galvanized pipe is poor.
Galvanized steel tube: hot dip galvanized steel tube steel tube substrate and molten plating solution composite physical, chemical reaction, forming a dense zinc iron alloy layer corrosion resistant structure. The alloy layer is integrated with the pure zinc layer and the steel tube substrate. Therefore, its corrosion resistance is strong.
Galvanized steel pipe: The zinc layer of cold galvanized steel pipe is an electric coating, and the zinc layer is separated from the steel pipe substrate. The zinc layer is very thin, and the zinc layer is simply attached to the steel tube substrate, which is easy to fall off. As a result, its corrosion resistance is poor. In new homes, the use of cold galvanized steel pipes as water supply is prohibited
