Description
A GI Long Bend is a galvanized pipe fitting used to change the direction of flow in a piping system with a long radius curvature. The long radius design ensures smooth fluid flow with minimum pressure loss and reduced turbulence. GI long bends are widely used in water supply systems, plumbing, irrigation, fire fighting, and industrial utility pipelines where efficient flow is important.
Material & Construction
- Material: Galvanized Iron / Mild Steel with Zinc Coating
- Coating Type: Hot-Dip Galvanized Finish
