Product Description
Haokun's series of Lap joint flange is a two-piece device, much like a welded flange, but also like a loose sliding flange. One is a sleeve called the "short end" and the other is a backing flange. Lap joint flange has the same dimensions (O.D., bolt ring, bolt hole size, etc.) as any other flange, but it has no raised face. One side, back, with a slight shoulder, square cut at center or tube hole. The front face has a plane and a fillet in the center hole to match the fillet.
