Socket Welding Flanges (SW Flanges) By wilsonpipeline.com

Socket Welding Flanges (SW Flanges) are similar to the slip-on flange, same to socket welding flange, but the bore is counter-bored to accept pipe. The diameter of the remaining bore is the same as the inside diameter of the pipe. The Socket Welding Flange is attached to the pipe by a fillet weld around the hub of the flange. An optional internal weld may be applied in high stress applications. The biggest use of Socket Flanges is in high pressure systems such as hydraulic and steam lines.

Socket welding flanges are counter bored to accept the pipe before being fillet welded. The bore of the pipe and flange are both the same therefore giving good flow characteristics. We have with industrial experts who design these flanges with excellence. The Socket welding flanges are offered at market leading rates.

The socket welding flanges are 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 diamter of the smaller bore is the same as the I.D. of the matchine pipe A restriction is built into the bottom of the bore which sets as a shoulder for the pipe to rest on. This is eliminates any restriction in flow when using a socket welding flange.
