Slip On Bossed Flange


Slip-on flanges are designed to slip over the pipe and are machined with the inside diameter of the pipe flange slightly larger than the outside diameter of the pipe.

These allow the flange to slide over the pipe and are joined to the pipe with a fillet weld at the top and the bottom of the flange.

A bossed type has a reinforcing disc around the outside of the pipe which helps support the pipe making for a stronger joint.

Usually machined from forgings for strength.
