ANSI B16.5 Socket Welding Flanges

Socket welding flange is similar to a slip-on flange except it has a bore and a counterbore dimension. The counterbore is slightly larger than the O.D. of the matching pipe, allowing the pipe to be inserted into the flange similar to a slip-on flange. The diameter of the smaller bore is the same as the I.D. of the matching pipe A restriction is built into the bottom of the bore which sets as a shoulder for the pipe to rest on. This eliminates any restriction in flow when using a socket welding flange.

Product Description

CLASS 150LBS FLANGE

Notes

(1) For the 'Bore'(B1) other than Standard Wall Thickness, Refer this

(2) Class 150 flanges except Lap Joint will be furnished with 0.06" (1.6mm) raised face, which is included in 'Thickness' (t) and 'Length through Hub' (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 1 degree. To accomplish parallelism, spot facing is carried out according to MSS SP-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 manufacture's option.

CLASS 300LBS FLANGE

Notes

(1) For the 'Bore'(B1) other than Standard Wall Thickness, Refer this

(2) Class 300 flanges except Lap Joint will be furnished with 0.06" (1.6mm) raised face, which is included in 'Thickness' (t) and 'Length through Hub' (T1), (T2).

(3) For Slip-on, Threaded, Socket Welding and Lap Joint Flanges, the hubs can be shaped either vertical from base to to 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.

(6) Depth of Socket (Y) is covered by ANSI B16.5 only in sizes through 3 inch, over 3 inch is at the manufacture's option.

CLASS 600LBS FLANGE

Notes

(1) For the inside diameter of pipes (corresponding to‘Bore’(B1) of Welding Neck Flanges), Refer this

(2) Class 600 flanges except Lap Joint will be furnished with 0.25" (6.35mm) raised face, which is included in 'Thickness' (t) and 'Length through Hub' (T1), (T2).

(3) For Slip-on, Threaded 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 with the same hub as that used for Slip-on Flanges or without hub.

(6) Dimensions of sizes 1/2" through 31/2" are the same as for Class 400 Flanges.

(7) Depth of Socket (Y) is covered by ANSI B16.5 only in sizes through 3 inch, over 3 inch is at the manufacture's option.

Notes

(1) For the inside diameter of pipes (corresponding to‘Bore’(B1) of Welding Neck Flanges), Refer this

(2) Class 900 flanges except Lap Joint will be furnished with 0.25" (6.35mm) raised face, which is included in 'Thickness' (t) and 'Length through Hub' (T1), (T2).

(3) For Slip-on, Threaded, 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.

(6) Dimensions of sizes 1/2" through 21/2" are the same as for Class 1500 Flanges.

(3) For Slip-on, Threaded Lap Joint and Socket Welding Flanges, the hubs can be shaped either vertical from base to top or tapered within the limits 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 1 degree. To accomplish parallelism, and facing is carried out according to MSS SP-9, without reducing thickness (t).

(6) Dimensions of sizes 1/2" through 21/2" are the same as for Class 900 Flanges.

(7) Depth of Socket (Y) is covered by ANSI B16.5 only in sizes through 21/2 inch, over 21/2 inch is at the manufacturer's option.
