The product standard name for hot-dip galvanized steel pipes is "Hot-dip Galvanized Welded Steel Pipes for Low-pressure Fluid Transportation." These pipes are produced by hot-dip galvanizing both the inner and outer walls of the welded steel pipes, resulting in zinc coatings on both surfaces, significantly enhancing their corrosion resistance to about 20 times that of standard steel pipes. Hot-dip galvanized steel pipes are widely used as transmission pipelines or metal structures in fire protection projects, natural gas transmission, oil processing industries, hydraulic engineering construction, and residential buildings.
Specification: Hot-dip galvanized round tubes (DN15-DN300); hot-dip galvanized processing for round and square tubes, and hot-dip galvanized processing for spiral weld pipes (Ф219-Ф1420mm)
Application: Used for the conveyance of low-pressure fluids such as water, wastewater, gas, fire protection, air, oil, and heating steam, as well as for mechanical structures.
