Duration: 5 Days
Overview:
This course provides a thorough review of a wide variety of causes of process plant piping vibration from the point of view of an engineer who must identify the cause of vibration, determine if vibration is excessive, and correct the problem if it is. It provides a background on fundamental causes of piping vibration and how to identify the source of vibration, rules of thumb and simplified methods for evaluating vibration severity, and methods of treatment. A wide variety of causes of vibration are covered in order to enable the participant to properly evaluate the variety of piping vibration problems that can occur in piping systems.
Course Objectives:
At the end of this course, the participants will be able to:
- Identify and evaluate different types of fluid-induced vibrations and their impact on piping system integrity.
- Apply signal processing and data acquisition techniques for effective vibration monitoring and diagnostics.
- Interpret vibration data to differentiate between common fault conditions such as imbalance, misalignment, resonance, and mechanical looseness.
- Provide an integral, analytical/test approach to solving field vibration problems with an emphasis on piping vibration issues
- Provide a common language that supports a clear understanding for both the analyst and the test engineer of what each needs to solve vibration problems
