Slip-on Flanges

Slip on flange is a type of steel flange which slides over the end of steel piping and then welded in place. Because the pipe slips into the flange before welding, it has a low hub. The inside and outside of the flange are both welded, resulting in sufficient strengh and no leak.

The slip-on flange is positioned so the inserted end of the pipe or fitting is set short of the flange face by the thickness of the pipe wall plus 1/8 of an inch, which thus allows for a fillet weld inside the SO flange equal without doing any damage to the flange face. The back or outside of the slip-on flange or SO flange is also welded with a fillet weld.
