4x 2 hour (Live Instructor-Led) sessions normally across 2 days. Each 100 – 120 minutes.
Benefits from attending
Gain an understanding of Pipework Vibration, including the main causes and consequences of pipework vibration.
Learn how to perform an initial visual assessment of pipework to be able to identify and prioritise potential areas of concern – supported by photo library of examples.
Learn about portable vibration measurement instrumentation and how to perform basic vibration measurements and assessments against Energy Institute limits.
Gain an understanding of other specialist techniques and when these should be used.
Gain an understanding of how to deal with common vibration problems.
Gain an understanding of the selection and implementation of remedial pipe supports, including SBC braces, visco dampers and dynamic vibration absorbers (tuned mass dampers) – illustrated by case studies.
Learn what constitutes ‘good practice’ for avoidance of vibration induced fatigue.
