Engineering and Consulting Services: Piping Vibration Analysis

Piping vibration induced fatigue and failures have been recognized in industry as an issue for decades. Despite this, most standards and guidelines (e.g. Piping code ASME B31.1, ASME B31.3, etc.) provide little detail on how to mitigate vibration risks. We will try to fill this knowledge gap.

New methodologies technically utilized to design and assess vibration of pipework in oil, gas, and petrochemical industries, and also thermal power plants during various stages of a project, as defined below. To prevent from irreparable damages, to decrease cost resulting from maintenance and unit outage period, to implement preventive actions for risk of vibrations, and to control the risk and probable problems in the design of piping system are services supplied by ACE. Moreover, inspection techniques, preventative methods and techniques, practical corrective actions, and tips and tricks on piping vibration will be conducted by ACE.
