Slip-on flange is a general flange type for ASME and DIN flanges. Different from welding-neck flange, slip on flange is without neck and need the pipe insert into the hole to welding. 
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.
