Weld neck flange measurements are canvassed in ASME B16.5 – which spreads Pipe Flanges and Flanged Fittings for size NPS ½" to 24" for above NPS 26" to 60" it ought to be according to ASME B16.47.
During a dimensional assessment of weld neck spine, you should check for External and Inner Diameter of body, Jolt Circle and Bolt opening Diameter, Length of the Hub, Straightness and arrangement of the jolting opening, the thickness of weld end
