A lap-joint flanges is a two-part assembly that consists of a stub end with a lap-joint ring flanges placed over it. After butt welding the stub end to the pipe, the flange ring can be rotated to align with the mating flange. This flanges connection is especially useful for large or difficult-to-adjust flanges.

  • The most significant limitation of lap joint flanges use is pressure ratings.
  • Contaminants can easily collect in the crevices formed between the internal surface of the flanges bore and the external surface of the stub ends.
  • At the design temperature specified by ASME B31.3, longitudinal stresses caused by pressure, weight, and thermal expansion may accumulate and exceed the basic allowable stress.

  • Lap Joint flanges can swivel freely around the pipe. This makes it easier to align opposing flange bolt holes.
  • Because these flanges are not in contact with the fluid inside the pipe, they are more durable.
  • The lap joint flanges in corroding or eroding piping systems can be salvaged for re-use.
  • Lap joint flanges have a low pressure-holding capacity. However, it outperforms slip-on flanges.
