Specifications And Uses Of GI Pipes

GI Pipes or Galvanized Iron Pipes are widely used for the purpose of conveying raw water and distribution of treated water in many rural water supply schemes, where the requirement of water is limited.


It is dipped into zinc for protection against corrosion and they are manufactured using mild steel strips of Low Carbon Steel Coils. The steel strips are passed through a series of fin rolls to achieve a circular shape. The slit ends of the strips are then welded together by passing an electric current of high frequency across the edges. The welded steel pipes are then passed through sizing sections where any dimensional issues are corrected and are then cut into desired lengths by automatic cutting machines. Lastly, these are pressure tested for any leaks randomly.


GI pipes are categorized into light, medium and heavy. Here is how you can determine –

• Light (Class A) - Marked in yellow color for identification.
