Slip-on flanges, abbreviated as SOF, are designed to slip over the outside of pipe, long-tangent elbows, reducers, and swages.  The flange has poor resistance to shock and vibration.  It is easier to align than a weld neck flange.  This flange is ideal for low pressure applications since the strength when under internal pressure is about one third that of a weld neck flange.  This flange has a raised face.

 

 

 

 

 

 

Slip-on Flange Datasheets

The datasheets we have on this site are shown below.  For simplicity sake, only datasheets that adhere to B16.5 are shown.  ASME B16.5 covers flange dimensions from ½” to 24”.  For sizes larger than this, please visit our flange datasheets page.
