API flanges are manufactured for high strength operating refinery systems with products such as oil and explosive gases. The flange standards API 6A and ASME/ANSI B16.5 have the same dimensions – but the API 6A flanges are rated for higher pressures.
Through forging process, using mold forming, and then through machining to complete the product processing.
