Lap Joint Flanges have all a similar common dimensions as the other flange named on this page however it doesn’t have a raised face, they utilized in conjunction with a “Lap Joint Stub End.” These lap joint Flange are nearly just like an error On flange except for a radius at the intersection of the flange face, and therefore, the bore to accommodate the Lap Joint Flange portion of the Stub End. Their pressure-holding ability is small, if any, better than that of slip on flanges, and also the fatigue life for the assembly is just one tenth that of Welding Neck flanges. They’ll be used in the least pressures and are available during a Full-size range. These flanges slip over the pipe, and aren’t welded or otherwise fastened to that. Bolting pressure is transmitted to the gasket by the pressure of the flange against the rear of the pipe lap (Stub End).
Lap welding joints are used most frequently to joint two pieces with differing thicknesses together. Also, considered a fillet type, the weld are often made on one or each side. A lap joint is made when 2 pieces are placed in an over lapping pattern on top of every other.

Advantages of Lap Joint Flanges
- Lap Joint Flanges have the freedom to swivel round the pipe. This facilitates the liner from opposing flange bolt holes.
- Lack of contact with the fluid inside the pipe results in the greater durability of those flanges.
- In piping systems which corrode or erode quickly, the lap joint flanges is also salvaged for re-use.
- The pressure-holding capacity of lap joint flanges is small . But it’s better than that of slip-on flanges.
- The lap joint Flange works as a backing ring on the stub End.
- The main advantage of lap joint flange is that the bolt holes are often aligned with the matching flange after the welds are completed.
- They allow rotational alignment capability.
Features of Lap Joint Flanges
- Recommended in applications that need frequent dismantling of the flanges and pipe.
- Used with an identical stub-end insert.
- Can rotate to allow for a simple alignment of bolt holes.
- Not recommended in high-pressure temperature applications.
