​Bulging is a common damage type in coke drums that can lead to cracks, leaks, and fires. It is also one of the primary causes of premature drum replacement. In the 2013 API survey of coke drum operators, 98% of respondents reported using laser scanning, effectively becoming the starting point of most coke drum mechanical integrity management programs. 

What is the Coke Drum Laser Scanning Process?

Ameriscan uses the most advanced laser scanners to provide an accurate dimensional profile of new and in-service coke drums without the need for error-producing vibration filters. By using modern high-definition capabilities, detailed images and millions of data points are collected by portable equipment in less than an hour between coking cycles.

Inspection findings help reveal critical details, including bulging dimensions and cladding failures that can be used to assess mechanical integrity and prioritize and guide repair efforts. In addition to avoiding unplanned shutdowns and costly failures, when multiple scans are taken over several years, historical trends can be used to conduct engineering assessments and make timely decisions about drum life extension or replacement.
