FORGINGS
Forged Pipe Flanges
WNRF, SORF, BLRF flanges in pressure classes 150# to 2500#.
ASME B16.5 / B16.47 | 1/2" to 24"
High-tensile forged round bars, stepped rotor shafts, eccentric pins, and turbine drive spindles with longitudinal metallurgical grain alignment.
Forged under heavy industrial hammers and hydraulic presses to achieve complete core consolidation, AFI shafts withstand high cyclic torsional stress, shock loads, and severe mechanical vibration in pumps, compressors, marine propulsion, and heavy power transmissions.
Comprehensive material grading, dimension compliance, and pressure-temperature ratings.
