A lap joint flange is a two-segment assembly, with a stub end that has a lap-joint ring flange put over it. The stub end is then butt welded to the pipe, and the flange ring can be turned to align with the mating flange.
The stub end can be viewed as a length of pipe sleeve with one end butt welded and the other end flared at the right angle to the pipe axis. The lap joint flange and stub end compose a two-piece composite lap joint connection.
These flanges are nearly identical to a "Slip Flange" except for a radius at the intersection of the flange face and the bore to accommodate the flanged portion of the Stub End. Their pressure-holding ability is a little better than that of "Slip On Flange". However, fatigue life is only one-tenth of "Welding Neck Flange".
Lap joint flanges slip over the pipe, and are not welded or otherwise fastened to it. They are a type of flange assembly commonly used in low-pressure systems or applications where frequent disassembly may be required.
