Pipework Failure Mechanism – 4 Key Steps

/ Small Bore Connections, Tech Library / By
  1. The majority of all Pipework Vibration Failures occur at Small Bore Connections (SBCs).
  2. Frequently, small (normal or abnormal operational) vibration levels on a main line can excite increased levels of vibration of vulnerable SBCs.
  3. Poor geometry / location of the SBC can result in damaging stress levels at the welded interconnection between the SBC and the Main Line.
  4. Over time, these operational stress cycles can result in through-wall fatigue fractures and resulting leakage from the pipework (HCR).
