What Are Weld Neck Flanges?

Click to Expand A weld neck flange has a long tapered hub that transitions smoothly to the pipe or fitting it is welded to. It is typically butt-welded to the line, meaning the end is inserted into the flange and then welded around the circumference. This creates a strong and leak-proof joint. The hub also…

What Are Slip-On Flanges?

Slip-on (SO) flanges are a type of flange that has a flat face on the sealing surface and are typically used in low-pressure applications. They are called “slip-on” because they can be easily slipped onto the end of a pipe or fitting and then welded in place. They also have a bored-out inner diameter that…
