What is the temperature of hot dip galvanized pipe?

Hot-dip galvanized pipes are made by heating the steel pipe to a high temperature of about 450℃, melting its surface and immersing it in molten zinc liquid, thereby forming a layer of zinc coating on the surface of the steel pipe. This process ensures that the zinc forms a tight bond with the surface of the steel pipe, providing excellent corrosion resistance.

Since the steel pipe is heated to a very high temperature during the hot-dip galvanizing process, hot-dip galvanized pipes have a higher applicable temperature range than electro-galvanized pipes. Generally, the applicable temperature range of hot-dip galvanized pipes is be

tween -40℃ and 200℃, which allows it to maintain stable performance in a variety of environments and applications.
