ANSI/ASME B16.5 Slip On Flange Dimensions
Slip On flanges (SO flanges/Slip-on flanges) 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 flanges or SO flanges are commonly lower in price than weld-neck flanges, and to this effect are a popular choice 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 life expentancy 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.

How to measure slip-on flanges?
Take the measurements of:
- OD: Outside Diameter
- ID: Inside Diameter
- BC: Bolt Circle
- HD: Hole diameter
Key Features:
Some important features are as follows:
- One size fits all pipe schedules.
- Fabricators can more easily cut pipe to length for slip-on flanges.
- The smaller thickness of this flange allows for easier alignment of bolting holes.
- They are generally not preferred for high pressure temperature environments.
Slip On Flange Dimensions & Approximate Masses
ANSI/ASME B16.5 Slip On Flange FF & RF Class 75 (in)
- Industry Standard Flanges have no national standard code or are they covered by any governing body.
- Bolt circle diameters are 1/8 inch larger than bolt diameter.
