The difference between ASME/ANSI and API flanges is the fabrication material and the higher rated API operating pressure.
ASME/ANSI flanges are common in industrial process systems handling water, steam, air and gas.
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 are similar dimensionally - but the API 6A flanges are rated for higher pressures.
