Forged Pipe Flanges
WNRF, SORF, BLRF flanges in pressure classes 150# to 2500#.
ASME B16.5 / B16.47 Weld Neck, Slip-on, Blind, Socket Weld, and Threaded Flanges engineered for extreme pressure-temperature process pipelines.
Ankita Forge Industries manufactures premium closed-die and open-die forged flanges designed for critical interconnects in oil & gas refining, chemical processing, and power plants. Every flange is manufactured from prime vacuum degassed steel billets with continuous circumferential grain flow, strictly complying with ASME Section VIII and pressure equipment directives.
Comprehensive material grading, dimension compliance, and pressure-temperature ratings.
