ANSI Lap Joint Flange are one such flange type popular in both piping and duct system design. A Lap Joint Flange is used in conjunction with a stub end where the flange is slipped over the stub end fitting which is then connected to either to pipe or another fitting by welding or other mechanical means.
ANSI Lap Joint Flange is not fixed and is left loose for proper alignment with the connection it is matching to. The benefits of this assembly is if there is frequent or rapid disassembly and assembly during maintenance of the piping system. The ability to spin and position the flange compensates for any misalignment of the bolt holes during reassembly.
This means you can match the piping materials as required where components touch piped materials while using more affordable -- or otherwise desirable -- materials in the outer components which do not interact with piped materials.
In addition, the lap joint flanges can be freely realigned and rotated to ensure proper connection and speed up maintenance processes in systems that require frequent maintenance.
The ability to utilize flanges that do not require filet welds on the plates can also decrease installation times and provide further upfront cost savings.
Finally, in high-corrosion or high-erosion processes, Lap joint flanges allow you to salvage the flange for re-use while replacing Stub Ends or Angle Rings as required for safe, cost-effective operation.
