Hot-dip galvanized steel pipe, also known as "hot-dip galvanized welded steel pipe for low-pressure fluid transportation," is a specially treated steel pipe. Its manufacturing process involves coating the inner and outer walls of the welded steel pipe with a layer of zinc through hot-dip galvanizing technology, significantly enhancing its corrosion resistance, which is approximately 20 times that of ordinary steel pipes.

 

 

Common Specifications of the Product

 

Hot-dip galvanized steel pipes come in various specifications to meet different application needs. Common specifications include round pipes ranging from DN15 to DN300, with outer diameters from 21.3mm (DN15, or 4-inch pipe) to 219mm (DN200, or 8-inch pipe). Additionally, spiral welded pipes with diameters from Ф219 to Ф1420mm are also available for hot-dip galvanizing. These steel pipes are used for transporting low-pressure fluids such as water, sewage, gas, fire protection, air, oil, and heating steam, as well as for constructing mechanical structures.

Product Advantages

 

1.Excellent Corrosion Resistance: The hot-dip galvanizing process forms a solid zinc-iron alloy layer on the steel pipe, effectively preventing it from corrosion.

 

2.Uniform Galvanized Layer with Strong Adhesion: During the hot-dip galvanizing process, the high temperature of the zinc liquid allows it to fully react with the steel pipe surface, resulting in a uniform galvanized layer with strong adhesion.

 

3.Good High-Temperature Performance: Hot-dip galvanized steel pipes can operate stably in high-temperature environments without deformation or damage.

 

4.Long Service Life: Due to its excellent corrosion resistance, hot-dip galvanized steel pipes have a longer service life than ordinary steel pipes.
