Specifications And Uses Of GI Pipes
GI pipes, or Galvanized Iron pipes, are widely used for conveying raw water and distributing treated water in rural and urban water supply systems. They are especially preferred in areas where water demand is moderate and durability is essential.
These pipes are manufactured using low-carbon mild steel strips, which are formed into a circular shape through a series of fin rolls. The edges are welded using high-frequency electric current to create a strong joint. After welding, the pipes undergo sizing, cutting, and rigorous pressure testing to ensure quality and leak resistance.
Finally, they are dipped in molten zinc to form a protective coating that prevents corrosion and enhances long-term performance.
Categories of GI Pipes
GI pipes are classified based on thickness, strength, and application requirements:
1. Light GI Pipes
Designed for low-pressure applications such as small-scale water supply and domestic plumbing systems.
2. Medium GI Pipes
Used for general plumbing, irrigation systems, and moderate-pressure water distribution.
3. Heavy GI Pipes
Built for high-pressure applications such as borewells, industrial water supply, and structural installations.
Understanding these categories helps in selecting the right gi pipe for specific project requirements.
