Piping Vibration Analysis and Practical Engineering Solutions in Process Plants
Piping Vibration Analysis and Practical Engineering Solutions in Process Plants
OBJECTIVES
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 that must identify the cause of vibration, determine if vibration is excessive, and correct the problem if it is.
WHO SHOULD ATTEND?
This course directed towards engineers responsible for operating piping systems. However designers of new piping systems will also find the broad coverage of potential vibration problems a time saving briefing on the variety of vibration problems that can occur in piping systems.
