Application range of slip-on flange:

Slip-On flanges or SO flanges are commonly lower in price than weld-neck flanges, so to some extent, it is most popular for our customers. However, customers should bear in mind that this initial cost saving may be diminished by the additional cost of the two fillet welds required for proper installation. Moreover, weld-neck flanges have a higher lifespan than slip-on flanges under duress.

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.
