Socket weld flange simplified as SW flange, it has a recessed area (like a shoulder) in the flange bore, this shoulder serves as a guide to set the depth of the pipe that inserted to the flange. Socket welding flange initially designed for high pressure small diameters piping system.
Socket weld flanges are a less common but equally effective connection for flanges which require less overall available space than a traditional weld neck flange, with a counterbore in the center to allow for a clean weld of pipe into the socket.
Usually furnished in smaller nominal pipe sizes, these make an excellent alternative to weld necks and slip ons when necessary. An assembly with limited space may be an instance in which a socket weld is selected, provided the pressure class is comparatively low and the fluid is not corrosive or for extremely high temperature service.
These socket flanges connect to square end pipe with a fillet weld at the ID of the hub of the socket, as the pipe is designed to sit almost flush against the counter bore of the flange. The expansion gap between the end of the pipe and the counter bore leaves just enough space for the welder to adjust the pipe within the connection. It is important to note that a butt weld pipe connection is not recommended for suiting to a socket counter bore connection when a square end pipe connection is possible.

Socket Weld Flange vs. Slip-On Flange |
| An RF socket weld flange features a small raised portion around the flange bore, serving as a seat for the gasket, promoting effective sealing. | The RTJ type entails a groove on the raised face surface, allowing for the placement of a gasket ring to enhance sealing performance. | A socket weld flange closely resembles a slip-on flange, but it distinguishes itself by having a shoulder within the inner bore. |
