Pipework Vibration Level 2

Advanced

4x 2 hour (Live Instructor-Led) sessions normally across 2 days. Each 100 – 120 minutes.

Benefits from attending

  1. Gain a greater understanding of Pipework Vibration, including the main causes and consequences of pipework vibration.
  2. Learn about theoretical ‘Quantitative Assessment’ methods for calculating ‘Likelihood of Failure’ (LOF) for Main Lines, Small Bore Connections and Thermowells, including identification of the most relevant parameters which can be used for corrective actions.
  3. Worked examples of Quantitative Assessment methods. 
  4. Learn how to use temporary strain gauges to collect dynamic stress data for fatigue assessment.
  5. Learn how to perform a basic fatigue life estimate or detailed assessment based on BS 7608. 
  6. Gain a greater understanding of the selection and implementation of remedial pipe supports, including SBC braces, visco dampers and dynamic vibration absorbers (tuned mass dampers) – illustrated by real-life case studies.
  7. Learn the top 10 most common mistakes which result in a high risk of vibration-induced fatigue failures.
