25 and 50# pipe flange specifications - steel flange thickness
25 and 50# pipe flange specifications - steel flange thickness
(OP)
I've spent some time Googling and searching parchment in the corporate archives and this forum, and found some bolt pattern info, but have not found references to specs or standards for flange thickness for piping under 125 #/class.
Does anyone know if such things exist, and where?
thanks

125# is a cast iron rating. FYI ...bolt hole dimension match 150# steel ANSI flanges

Well, it is electrical generation related in a far-fetched kind of way.
Coal piping for pulverized coal powerplants falls under NFPA guidelines. 50 psi design pressure is called for.
There are miles of existing flanged coal pipes serving faithfully even as we speak. Some with welded steel flanges with thickness down to 3/8".
75 and 125 class Flange thickness for pipes 8 - 26 inches diameter are going to be at least an inch thick.
When coal pipe is replaced it would be appropriate to simply upgrade to the "standardS" driven thickness, but only if 3/8" is really too thin.
