GENERAL NOTES:(a) Dimensions are in millimeters. For dimensions in inch units, refer to Table II-5 of Mandatory Appendix II.(b) For facing requirements for flanges and flanged fitting, see para. 6.4.1 and Fig. 7.(c) For facing requirements for lapped joints, see para. 6.4.3 and Fig. 7.(d) See para. 4.2.7 for marking requirements.(e) Use Class 600 sizes NPS 1⁄2 to NPS 31⁄2 for Class 400.(f) Use Class 1500 in sizes NPS 1⁄2 to NPS 21⁄2 for Class 900.

NOTES:(1) The height of the raised portion is equal to the depth of the groove dimension, E, but is not subjected to the tolerances for E. Former

full-face contour may be used.(2) For ring joints with lapped flanges in Classes 300 and 600, ring and groove number R30 is used instead of R31.

GENERAL NOTE: Dimensions are in millimeters. For dimensions in inches, refer to Mandatory Appendix II, Table II-6.

NOTES:(1) The hub dimensions shall be at least as large as those of the standard flanges of the size to which the reduction is being machined,

except flanges reducing to a size smaller than those of Columns 2, 4, and 6 may be made from blind flanges (see Example).(2) Class 150 flanges do not have a counterbore. Class 300 and higher pressure flanges will have depth of counterbore Q of 7 mm for

NPS 2 and smaller tapping and 9.50 mm for NPS 21⁄2 and larger. The diameter Q of counterbore is the same as that given in the tablesof threaded flanges for the corresponding tapping.

(3) Minimum length of effective threads shall be at least equal dimension T of the corresponding pressure class threaded flange as shownin tables but does not necessarily extend for the face of the flange. For thread of threaded flanges, see para. 6.9.

(4) For method of designating reducing threaded and reducing slip-on flanges, see para. 3.3 and Examples below.

EXAMPLES:(1) The size designation is NPS 6 � 21⁄2 — Class 300 reducing threaded flange. This flange has the following dimensions:

NPS 21⁄2 p taper pipe thread tapping (ASME B1.20.1)320 mm p diameter of regular NPS 6 Class 300 threaded flange

35 mm p thickness of regular NPS 6 Class 300 threaded flange178 mm p diameter of hub for regular NPS 5 Class 300 threaded flange. Hub diameter may be one size small to reduce machin-

ing. In this example, a hub diameter of NPS 21⁄2 would be the smallest acceptable.15.5 mm p height of hub for regular NPS 5 Class 300 threaded flange

(2) The size designation is NPS 6 � 2 — Class 300 reducing threaded flange. Use regular NPS 6 Class 300 blind flange tapped with NPS 2taper pipe thread (ASME B1.20.1).

GENERAL NOTES:(a) Dimensions of Table 14 are in millimeters, except for the diameter of bolts and bolt holes, which are in inch units. For dimensions in inch units, refer to

Mandatory Appendix II, Table II-7.(b) For tolerances, see section 7.(c) For facings, see para. 6.4.(d) For flange bolt holes, see para. 6.5 and Table 13.(e) For spot facing, see para 6.6.(f) For reducing threaded and slip-on flanges, see Table 6.(g) Blind flanges may be made with or without hubs at the manufacturer’s option.(h) For reducing welding neck flanges, see para 6.8.

NOTES:(1) This dimension is for the large end of the 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.(2) For welding end bevel, see para. 6.7.(3) For thread of threaded flanges, see para. 6.9.(4) Socket welding flanges may be provided in NPS 1⁄2 through NPS 21⁄2, using Class 600 dimensions.(5) To be specified by the Purchaser.
