A stub end with a lap-joint ring flanges fitted over it make up a two-part assembly known as a lap-joint flange. The flange ring can be moved to align with the mating flange after butt welding the stub end to the pipe. For big or tricky-to-adjust flanges, this flanges connection is extremely helpful.

  • 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.
  • Type A: Flat Face (FF)
  • Type B: Raised Face (RF)
  • Type C: Tongue Face (TF)
  • Type D: Grooved Face (GF)
  • Type E: Spigo

  • 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.
