Achieving a Comprehensive Fired Heater Health Monitoring Program
By: Tim Hill, Principal Consulting Engineer, Quest Integrity
As seen in the September/October 2014 edition of Inspectioneering Journal
IR thermometry is an excellent diagnostic tool for detecting tube hot spots from internal fouling or non-uniform heat distribution in fired heaters, but to ensure the full capability of IR thermometry, operators should employ the right instruments for the job and implement a proven methodology to measure accurate temperatures in a repeatable process.
Convection Section Failure Analysis and Fitness-for-Service Assessment for an Ammonia Plant
By: James R. Widrig, Quest Integrity Group and Neil Schroetlin, Dakota Gasification Company
As published by the 2014 AIChE Annual Safety in Ammonia Plants and Related Facilities Symposium
A brittle fracture failure of several HK-40 tubes occured in the convection section of an ammonia plant feed gas heater. A failure analysis and API 579 Fitness-for-Service assessment were performed to determine the mode of failure and to determine the remaining life of the HK-40 tubes. This information provided the operator with a sound basis to evaluate the business and safety risks of continued operation until long-term repairs and system improvements could be implemented.
Alleviating the Challenges of Type B Inspections
By: Ron Kessler, RDVI Business Development North America
As seen in the July-August issue of Tank Storage Magazine
Historically, inspections for IFR Type B failures required a manned entry into the vessel. A confined space entry of this nature requires extensive planning and must be supported with product transfer, supplied air and an extensive lockout/tagout (LOTO) effort. However, a new solution utilizing remote digital video inspection (RDVI) techniques is now available for single seal tanks to alleviate the challenges associated with IFR Type B inspections.
Improving Reformer Pigtail Reliability
By: Nitrogen + Syngas with contributions from Quest Integrity's Charles Thomas and Matt Smillie
As seen in the July-August 2014 issue of Nitrogen + Syngas
Previously reformer outlet pigtails were considered standalone components with a nominal 100,000 hour lifespan. With improvements in reformer tube metallurgy and manufacture, pigtails are now seen as a weak link and often require replacement before the reformer tubes and manifolds. There is a strong incentive to improve pigtail reliability and lifespan, taking into account all the key factors, from design to material selection, metallurgy, grain size distribution, quality control or inspection techniques, and all the major focal points during the life cycle of these components.

Case Studies in the Application of Advanced Technology to Pipeline Flaw Assessment
By: Ted L. Anderson, Chief Technology Officer and Ian Smith, Senior Consulting Engineer at Quest Integrity
This paper was presented at the PPIM Conference in Houston, Texas February 2014
When it comes to evaluating flaws and other damage detected by ILI and other means, much of the pipeline industry still relies on simplified assessment methodologies that don’t take advantage of all data sources and improved understanding of failure mechanisms. This paper makes the case that adopting new technologies for flaw assessment is overdue, as these technological advances will be beneficial to the industry.

When Bad Things Happen to Good Pressure Vessels: A Story of Localized Metal Loss
By: Michael Turnquist, Consulting Engineer - Advanced Engineering, Quest Integrity Group
As seen in the Nov-Dec 2013 issue of Inspectioneering Journal
While there are many types of damage mechanisms that can occur in a piece of equipment, localized metal loss is one of the most common. If an inspection reveals that metal loss has occurred, many questions are raised: Can I continue operating? If so, for how long? Is a repair needed right away? Finding a solution to these questions can be difficult and costly. However, a solution can be reached through the application of finite element analysis (FEA) as outlined in API 579/ASME FFS-1 Fitness for Service1.
