Looking for ANSI B16.47 series A & B Flange bolting chart

Looking for ANSI B16.47 series A & B Flange bolting chart

Looking for ANSI B16.47 series A & B Flange bolting chart

(OP)
I'm working on a project that requires replacing some 36" pipe. I typically don't work with this large of diameter pipe. I've been able to find ANSI B16.47 series A & B Flange dimension tables but not bolting charts. Can anyone help?

Thanks, Lud

What do you mean by "Bolting Charts"?  What information would be contained in these charts?

Thanks for responding,

A chart of bolt diameters and lengths for each flange size and class rating similar to the bolting chart for ANSI B16.5 flanges that can be found at the Texas Flange Co's web site. http://www.industrialflange.com/dims/Bolting%20Chart.pdf

I was able to find a copy of API 605, which does list bolt lengths. This, if I'm correct, should match the ANSI B16.47 Series B. So at this point I'm still looking for bolting info. on the ANSI B16.47 Series A.

It looks like ASME B16.47 includes all the information.  Perhaps you are looking for a simple presentation with everything layed out together.  Table 4 reflects flange bolting dimension recommendations.  Annex C provides a method for calculating bolt lengths.  Table 1B lists applicable ASTM material specifications.  Table 4 lists flange bolting dimensional recommendations.  The typical dimensional tables such as Table 5 (for Class 150 series A) reflect the drilling requirements such as diameter of the bolt circle, number of bolt holes, diameter of bolt holes etc. based upon the nominal pipe size.

"It looks like ASME B16.47 includes all the information."

That's my problem. I have been unable to get my hands on a copy of ASME B16.47. I was hoping someone would be able to point me to something similar to the chart for B16.5 flanges that many flange manufactures publish for reference.

I've calculated the stud length that I need for my current project. I was just hoping to be able to have a complete chart for future use.

Thanks, Lud
