Top Weldneck Flange Manufacturers in India

Prayag Precitech offers weld neck flanges in a range of materials, including stainless steel, alloy steel, carbon and LTCS, copper & nickel alloys, Super Duplex, Nickel, Monel, Inconel, Hastelloy, Aluminium, and more. These flanges require butt welding for installation, providing exceptional integrity and performance in high-pressure and high-temperature systems with multiple bends. Weld neck flanges, also known as tapered hub flanges, distribute stress to pipes, effectively reducing stress concentration. There are two designs: one for pipes and another for process plants. Made through forging, these round fittings extend beyond the circumference rim and are welded to pipes.
