What is ANSI B16.47 Series A

The ANSI B16.47 standard of flanges and flange fittings specifically covers large diameter flanges, ranging from NPS 26 to NPS 60. They come in both stainless steel and high-carbon steel variants. It can withstand highly corrosive chemicals, which makes it suitable for a number of segments. This standard is specifically used in large scale mining operations, chemical refineries and oil refineries. Due to its higher bore diameter, it can withstand much higher pressures and temperatures than the ANSI B16.5 standard.

ANSI B16.47 Series A – Mainly used in pressure vessel applications where fluctuations in temperature and pressure are important.

ANSI B16.47 Series B – Mainly used in petrochemical applications and transmission lines.These flanges have smaller OD, Thickness and different drill pattern.
