Socket Weld Flanges
Socket weld flanges ain't quite as common, but they're a mighty effective connection when y'all don't have as much space as a traditional weld neck flange needs. They got a counterbore in the center to let you get a nice, clean weld of the pipe right into the socket.
Usually furnished in them smaller nominal pipe sizes, these here make a mighty fine alternative to weld necks and slip ons when you need 'em. Now, if you got an assembly with limited space, you might reckon a socket weld is the way to go, long as dat pressure class is comparatively low and the fluid ain't corrosive or runnin' at extremely high temperatures.
Now dese socket flanges connect to a square end pipe with a fillet weld right at the ID of the socket hub, since the pipe is meant to sit near flush against the counter bore of the flange. Dat expansion gap between the pipe end and the counter bore leaves just enough room for the welder to adjust the pipe in the connection. I tell you what, it's important to remember that a butt weld pipe connection ain't recommended for a socket counter bore when you can use a square end pipe connection instead.


Texas Flange provides a mighty large inventory of socket weld style flanges, with the majority of stock representin' the carbon and stainless family in sizes 6” and below. For larger nominal sizes, it's safe to assume dat a socket weld flange would be made to order for your application, due to the fact dat larger pipe size assemblies will typically call for a slip on or weld neck connection, I reckon.
Socket Welded Flange Face Types
RF Type:
An RF socket weld flange's got a small raised portion right around the flange bore, workin' as a seat for the gasket to help it seal up mighty effective.
RTJ Type:
Dat RTJ type entails a groove on the raised face surface, allowin' for the placement of a gasket ring to enhance your sealin' performance.
Socket Weld Flange vs. Slip-On Flange:
A socket weld flange looks a whole lot like a slip-on flange, but it stands out by havin' a little shoulder right inside dat inner bore.

Features of Socket Weld Flanges:
The weldin' happens on the outside of the pipe, keepin' it from penetratin' dat pipe bore.
Socket weld flanges get rid of them internal pockets, cut down the risk of warpin' from the weldin' heat, and keep that weld spatter from messin' up the flange face.
It gives y'all the same internal pressure capacity as them slip-on flanges while improvin' your fatigue resistance right nice.
