Diameter of Hub at Point of Welding ≤ 5 = + 2.4 mm / - 0.8 mm \| ≥ 6 = + 4.0 mm / - 0.8 mm	Drilling Bolt Circle = 1.6 mm \| Bolt Hole Spacing = ± 0.8 mm Eccentricity of Bolt Circle with Respect to Facing ≤ 2½ = 0.8 mm max. \| ≥ 3 = 1.6 mm max
Thickness ≤ 18 = + 3.2 mm / - 0 \| ≥ 20 = + 4.8 mm / - 0	Length thru Hub ≤ 10 = 1.6 mm \| ≥ 12 = ± 3.2 mm

Notes
1. Dimensions are in millimeters unless otherwise indicated.
2. T = Nominal wall thickness of pipe. Bevel for Wall Thicknesses T from 5 mm to 22 mm inclusive.
3. The length of the stud bolt does not include the height of the chamfers (points).
