Gi Pipe full from is Galvanized iron pipe
Gi Pipe undergoes a zinc coating process on its surface to enhance corrosion resistance and service life. Typically made from low-carbon steel, it is produced through either hot-dip galvanizing or pre-galvanizing processes.
Pre-galvanizing involves zinc coating applied to steel plates during production. For details, click the link.
Hot-dip galvanizing immerses formed pipes in molten zinc. For details, click the link.
Key advantages of Gi Pipe include: excellent corrosion resistance, relatively low cost, and suitability for outdoor or underground environments.
Zinc coating requirements for Gi Pipe: Zinc coating weight: 40 g/m² – 600 g/m², Common thickness: 40 μm – 85 μm.
Zinc coating principle: Prevents oxidation by isolating steel from air exposure, Extends pipe lifespan through sacrificial anode protection.
Typically, galvanized pipes achieve a 20-50 year service life extension.
