An MS Flange (Mild Steel Flange) is a mechanical component used to connect pipes, valves, pumps, and other equipment in a piping system. Flanges provide a strong, leak-proof, and detachable joint, making installation, inspection, and maintenance easy. MS flanges are widely used in water supply, oil & gas, fire fighting, HVAC, fabrication, and industrial piping systems due to their strength, durability, and cost-effectiveness.
