Material Specifications & Manufacturing
Forged flanges manufactured according to ASME B16.47 Series A standards are produced as one piece in accordance with applicable material specifications. The forging process (die forging or open-die forging) is a compressive plastic hot working operation that consolidates material to flow in directions most favorable for resisting service stresses.
