Definition and Details of Slip on Flange:

The calculated strength from a Slip On flange under internal pressure is of the order of two-thirds that of Welding Neck flanges, and their life under fatigue is about one-third that of the latter.
The connection with the pipe is done with 2 fillet welds, as well at the outside as also at the inside of the flange.
The X measure on the image, are approximately:
Wall thickness of pipe + 3 mm.
This space is necessary, to do not damage the flange face, during the welding process.

Advantages of Slip on Flange:

A disadvantage of the flange is, that principle always firstly a pipe must be welded and then just a fitting. 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.

Uses of Slip on Flange:

Slip-on flanges are a popular type of pipe flanges. These are type of flanges that slide over the end of piping and then welded in place. These flanges are ideal for lower pressure applications. These are easily fitted and welded into different pipes. Welding reduces fabrication costs of these pipes

1. Slip On flange 2. Filled weld outside
3. Filled weld inside 4. Pipe
