Slip-On flanges also called SO flanges

　　Slip-On flanges also called SO flanges are commonly lower in price than weld-neck flanges. So for this reason the so flange is a popular choice for our clients. 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. What’s more, weld-neck flanges have a long life time than slip-on flanges under the using process.

　　The SO 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.
