Mild Steel Flanges in Kolkata
Mild steel flanges are workhorse components in pipe fitting systems, extensively used to connect pipes, valves, and equipment. Made from low-carbon steel (0.05%-0.25% carbon content), they offer an excellent balance of affordability, weldability, and strength. Our range includes slip-on flanges, threaded flanges, blind flanges, and flanged elbows — manufactured to ASTM A53 and ANSI/ASME B16.5 standards.
