Slip-On Pipe Flanges. As made obvious by their name, these pipe flanges slip over the pipe. They're manufactured with an inside diameter that is slightly bigger than the pipe's outside diameter. These attachments are connected to the pipe via fillet weld at the top and bottom of the flange.
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 life expentancy than slip-on flanges under duress.
Slip-on flanges are all bored slightly larger than the O.D. of the pipe. They are preferred over welding neck flanges bu many users due to their lower intial cost, but final intallation cost is probably not much less than that of the welding neck flange because of the additional welding involved.
It is welded both inside and out to provide suffcient strength and prevent leakage.
Weldneck and Slip-On Orifice Runs
Advantages of slip on flanges:
- Low cost installation
- Less time needed to spent on ensuring the accuracy of the cut pipe
- They are somewhat easier to align
- The slip-on flanges have low hub because the pipe slips into the flange before welding
- The flange is welded both inside and outside to provide sufficient strength
- They prevent leakage
Standards, Dimensions & Weight
Slip-on flange is slipped over the pipe and then fillet welded. Slip-on flanges are easy to use in fabricated applications.
- ASME/ANSI B16.5 Class 150 SO 300 SO 600 SO 900SO
- BS 3293 Class 150SO 300 SO 600SO
- DIN 86029 PN 10
A combination of flange and elbow or flange and tee is not possible, because named fittings have not a straight end, that complete slid in the Slip On flange.
