About Slip On Flanges
Slip-on flanges are basic hub and ring flanges designed for quick installation with piping. The pipe and/or tubing slides right into the bore of the flange, and then it gets welded on both sides: around the outside of the pipe and on the interior of the connection.
One of the things people like about slip-ons is how forgiving they are during fit-up. Since there's no weld bevel, you can slide the pipe back and forth to dial in the exact position before you commit to welding. The bore is intentionally sized with a little extra room, giving the welder and fabricator enough space to work comfortably.
You'll most often see slip-on flanges in lower-pressure applications. The standard version comes with a hub (that raised portion around the bore) which looks a lot like a raised face in terms of its dimensions but is generally much taller. If space is tight or the application allows for it, you can also get a "ring style" slip-on with no hub at all. Both versions are legitimately slip-on flanges; it just comes down to what your situation calls for. In higher pressure classes, slip-ons are sometimes made with the same hub height as a lap joint flange for a better connection. And if a lap joint isn't readily available, some customers will order a slip-on machined to lap joint dimensions as a practical workaround.
That said, slip-ons do have their limits. As pressure and mechanical stress increase, a weld neck flange becomes the better choice. The reason comes down to the weld itself: a slip-on uses a fillet weld, while a weld neck has a tapered hub that transitions smoothly into a full butt weld connection with the pipe. That taper is what gives the weld neck its edge in demanding service conditions.
