Many normal process operations can cause vibrations in pipework, due to a variety of excitation mechanisms, which over time can lead to fatigue fractures resulting in leaks. Vibration Induced Fatigue failures occur due to the progressive growth of fatigue cracks in welded connections due to fatigue mechanism.
Failure occurs weeks, months or often years after the first sign of the crack. At this point the crack has grown fully through-wall, resulting in a leak, often during an extreme event such as a pipe surge or pressure spike. Such fractures could lead to serious incidents involving major injury, fire, explosion or pollution. Many serious pipe vibration issues can be easily detected using simple vibration screening techniques and can be avoided by adopting industry best practice.
This course will provide a detailed introduction into pipework vibration to raise the knowledge, skills and confidence of engineers to be able to perform their own visual, basic vibration and strain surveys and assessments. It will also provide a good overview of common remedial solutions and other specialist techniques, and provide additional information on the selection and implementation of Braces, Visco-dampers and Dynamic Vibration Absorbers for corrective actions.
Emphasis is placed on both practical and theoretical aspects of the subject and covers in detail Quantitative Assessment Methods for the calculation of Likelihood of Failure (LOF) for main lines, small bore connections and Thermowells.
