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.

TOLERANCES:E (depth) +0.4, −0.0F (width) ±0.2P (pitch diameter) ±0.13R (radius at bottom)

R ≤ 2 + 0.8, −0.0R > 2 ± 0.8

Table 14 Dimensions of Class 400 Flanges (Cont’d)

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.
