Description
A socket weld flange joins a small-bore pipe to a valve, pump or other flange. The pipe slides into a socket in the flange and then gets one fillet weld on the outside. As a result, you get a strong joint with a smooth bore and no butt weld. We stock socket weld flanges at our showroom in Nad Al Hamar, Dubai.
First, match the flange class to the line pressure, for example Class 150 for water or Class 300 for steam. Next, give us the pipe schedule, because the socket bore must match it. Finally, choose carbon steel A105 for general service, or stainless steel 316L for chemicals and seawater. In addition, we stock weld neck, slip-on and blind flanges in the same classes.
Why Choose Our Socket Weld Flange
- Easy to align: The socket holds the pipe square while you weld.
- One weld only: Because there is no butt weld, fit-up is faster on site.
- Smooth bore: The bore matches the pipe, so flow stays clean.
- Traceable steel: In addition, EN 10204 Type 3.1 certificates are available on request.
