Lap Joint Flange / LJ Flange
Lap joint flanges use a stub end that is welded to the pipe. A ring flange fits loosely around the stub end, permitting easy flange alignment of the bolt holes. A lap joint flange is also called Van Stone or Stub Flange. The stub ends are available in three styles (Types A, B, and C) and two lengths (Short and Long).
