SLIP ON FLANGES

AAF 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 + 0.118″ inches / 3 mm.  This space is necessary, to do not damage the flange face, during the welding process.  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.

American Alloy Flange offers Slip On Flanges from ½” – 202″ in most alloys.
