Notes : (For 150# & 300# Class)

  • This dimension is for large end of hub, which may be straight or tapered. Taper shall not exceed 7 deg on threaded, slip-on, socket-welding, and lapped flanges. This dimension is defined as the diameter at the intersection between the hub taper and back face of the flange.
  • The minimum thickness of these loose flanges, in sizes NPS 3 ½ and smaller, is slightly greater than the thickness of flanges on fittings, which are reinforced by being cast integral with the body of the fitting.
  • For Class 300 these flanges may be supplied with a flat face. The flat face may be either the full tf dimension of thickness plus 2 mm or the tf dimension thickness without the raised face height.
  • Dimensions in Column 15 correspond to the inside diameters of pipe as given in ASME B36.10M for standard wall pipe. Thickness of standard wall is the same as Schedules.
  • To be specified by the Purchaser.
  • 2.0 mm (0.06 in.) raised face for Class 150 and 300 raised face flanges
