(1)For the 1 Bore ’ (B1) other than Standard Wall Thickness, refer to page 50, 51.
(2)Classl 50 flanges except Lap Joint will be furnished with 0.06" (1.6mm) raised face, which is included in 'Thickness* (t) and 1 Length through Hub1 (T1), (T2).
(3)For Slip-on, Threaded, Socket Welding and Lap Joint Flanges, the hubs can be shaped either vertical from base to top or tapered within the
limits of 7 degrees.
(4)Blind Flanges may be made with the same hub as that used for Slip-on Flanges or without hub.
(5)The gasket surface and backside(bearing surface for bolting) are made parallel within I degree. To accomplish parallelism, spot facing is carried out according to MSS AP-9, without reducing thickness (t).
(6)Depth of Socket(Y) is covered by ANSI B16.5 only in sizes through 3 inch, over 3 inch is at the manufacturer* s option.
