The product standard name for hot-dipped galvanized steel pipes is "Hot Dip Galvanized Welded Steel Pipes for Low Pressure Fluid Transmission." These pipes undergo both internal and external hot-dip galvanizing on the basis of焊接钢管道, resulting in zinc coatings on both the inner and outer walls, significantly enhancing the anticorrosive properties to about 20 times that of ordinary steel pipes. Hot-dipped galvanized steel pipes are widely used in fire engineering, natural gas transmission, petroleum processing industries, hydraulic engineering construction, and residential building construction as transmission pipelines or metal structures.
Specification: Hot-dip galvanized round pipes, DN15-DN300; hot-dip galvanized processing for round and square pipes, hot-dip galvanized processing for spiral weld pipes, φ219-φ1420mm.
Usage: Used for conveying low-pressure fluids such as water, wastewater, gas, fire protection, air, oil, heating steam, and for mechanical structures.
