Galvanized steel pipes are manufactured from low carbon steel and coated with zinc through hot-dip or electro-galvanizing processes, providing exceptional corrosion resistance and durability. These pipes are widely used across construction, chemical, electric power, machinery, and various industrial sectors.
Steel Pipe (Black Pipe) → Alkaline Washing → Water Washing → Pickling → Drying → Hot-dip Galvanizing → Cooling → Passivation → Pipe Cutting → Rinsing → Final Inspection
- Conveying pipelines for gas, heating gas, oil, water, and other fluids
- Oil industry applications including oil well pipes and offshore oil field pipelines
- Agricultural, construction, and aviation industry uses
Hot-Dip Galvanizing: Chemical process with zinc layer thickness exceeding 10μm, providing superior corrosion protection. Silver-white appearance, ideal for building construction.
Electro Galvanizing: Physical process with zinc layer thickness of 3-5μm. Smooth, bright surface with limited corrosion resistance.
