A Closer Look at ASME B16.2 Flanges in Industrial Piping Working in the industrial equipment sector for well over a decade, I’ve encountered countless flange standards, but ASME B16.2 often stands out in discussions about cast iron pipe flanges — and for good reason. These flanges are like the reliable, no-nonsense workhorses in many piping systems, especially in waterworks and low-pressure applications. Honestly, when I first dove into ASME B16.2 specs years ago, I thought it was just another standard, a page in a hefty binder that I’d skim over. But then, I started noticing how the details m…
