Minimum Wall Thickness of NPS 16, Class 900 Fitting

[Meck91]

I need help in finding minimum wall thickness of a class 900 fitting that is NPS 16. I have tried to look into ASME B16.9, but can't figure out. I seems to be very simple probably tricky.

Would highly appreciate any help.

Thanks,

Per B16.9 butt-weld fittings, one can specify the the wall thickness by the schedule number which is to match the pipe thickness. And, the Class 900 is the flange rating per B16.5.
