Auto-Refrigeration / Brittle Fracture

At SES, we use a comprehensive approach to identifying susceptible equipment, executing the brittle fracture analysis, and performing the process hazards analyses to evaluate and develop mitigation for at-risk vessels and piping.

HTHA Assessments

HTHA continues to be a process-safety issue within the refinery and chemicals industries. There is a growing industry need for HTHA damage assessments to assist with asset prioritization and capital planning. In response, we developed two new HTHA damage life assessment methods.

Vulnerability Assessments

Corrosion reviews of process units are routinely performed as part of a mechanical integrity program for pressure vessels and piping systems. We have the engineers experienced in process corrosion, inspection and mechanical integrity who can provide top-level corrosion vulnerability assessments.

Fire Damage Assessments

Recovering from a fire can be challenging and complex, but an experienced team can reduce the impact and restore operations quickly and safely. This begins with an incident safety evaluation of the site and confirmation of what equipment can be run, what must be repaired, and what must be replaced.

Turnaround Support

Turnarounds are high stakes activities where all the known issues are addressed via inspection, analysis and planning and the unknowns are discovered and dealt with, all in real time. We excel at providing comprehensive engineering support services in preparation for and during turnarounds.

Plant Engineering Services

SES provides timely and cost-effective engineering solutions to improve plant and refinery on-stream efficiency, safety, and reliability. Engineering Assessments - Field Services & Monitoring - Materials Engineering - Testing Services - and more

This article introduces portions of a “Best-In-Class” Fitness-for-Service (FFS) program that includes the performance of regular visual inspections of pipe supports and hangers, coupled with in-situ load testing of suspect supports. This program can give the plant engineer the knowledge he needs to make sound operational and maintenance decisions.

Combining High Resolution In-Line Geometry Tools and Finite Element Analysis to Improve Dent Assessments
May/June 2015 Inspectioneering Journal
By Rhett Dotson, P.E. at Stress Engineering Services

Historically, regulations regarding dent severity have been governed by one of two metrics: dent depth or strain. In the case of the former, plain dents with a depth up to 6% of the nominal diameter are permitted in both gas and liquid pipelines. However, many operators typically set stricter limits on dent depth targeting those above a depth of 2% for evaluation.

November/December 2014 Inspectioneering Journal
By Alphonse W. Hegger Jr., P.E. at Stress Engineering Services

Today, more than ever, refinery operators are focused on maintaining safe operations for their employees and extending the life cycle of valuable operating equipment to optimize efficiencies and avoid expensive unforeseen shutdowns. When process unit corrosion assessments, RBI methodologies, and IOWs are properly integrated into refining operations, the result is improved safety and longer run times.

Corrosion Under Insulation And Best-fit Solutions
July/August 2014 Inspectioneering Journal
By Brian J. Fitzgerald at Stress Engineering Services

As any refining or petrochemical plant manager knows, corrosion can occur on insulated piping at any facility, and is particularly difficult to prevent, track, and mitigate. Corrosion under insulation (CUI) has been a major challenge for the petrochemical and refining industries since the first pipelines were insulated with wrappings.

March/April 2014 Inspectioneering Journal
By Bobby Wright, P.E. at Stress Engineering Services, and Ralph E. King P.E. at Stress Engineering Services, Inc.

Recently, Inspectioneering Journal sat down with Stress Engineering’s Bobby Wright and Ralph King to discuss how companies can better transfer and preserve industry knowledge.

Auto-Refrigeration / Brittle Fracture Prevention And Process Safety Mitigation
November/December 2013 Inspectioneering Journal
By Ralph E. King P.E. at Stress Engineering Services, Inc.

Auto-refrigeration is a process where an unintentional and/or uncontrolled phase change of a hydrocarbon from a liquid state to a vapor occurs, resulting in a very rapid chilling (refrigeration) of the liquid containing local equipment and/or piping. This phenomenon can result in a catastrophic ‘break-before-leak’ scenario commonly referred to as brittle fracture.

High Temperature Life Assessment
May/June 2013 Inspectioneering Journal
By Greg Garic at Stress Engineering Services, Inc.

Predicting the remaining life of components operating in the creep regime is one of the trickiest problems encountered in the fitness-for-service (FFS) world.

Fitness-for-Service Assessment: Severe Local Corrosion
March/April 2013 Inspectioneering Journal
By Greg Garic at Stress Engineering Services, Inc.

If an operator finds cracking in a furnace waste heat boiler, excessive thinning in an absorption tower, or severe bulging in a converter, FFS assessments—not standard code analyses—are needed to evaluate the unit’s mechanical integrity. FFS assessments, according to the American Petroleum Institute (API), are “quantitative engineering evaluations that are performed to demonstrate the structural integrity of an in-service component containing a flaw or damage.”

Evaluating Fitness for Service of Damaged Equipment
September/October 2012 Inspectioneering Journal
By Peter Carter, PhD, PE at Stress Engineering, Inc., Joe Frey, PE at Stress Engineering, Inc., and Mike Guillot, PhD, PE at Stress Engineering, Inc.

An all too familiar scenario in power plants is one in which an inspection finding occurs late in an outage and consequently, the return to service date may need to be postponed to allow time for corrective action. Historically, cracks or thinned spots were typically repaired without question.

May/June 1997 Inspectioneering Journal
By John Brear at ERA Technology Ltd., John Williamson at ERA Technology Ltd., and Bobby Wright, P.E. at Stress Engineering Services

Reformer catalyst tubes are commonly manufactured from high strength, creep and corrosion resistant alloys. They are relatively thick walled and are usually produced by centrifugal casting. Their lives are limited by creep, driven by a combination of internal pressure and through-wall thermal stresses generated by operational transients. The typical composition for alloys for reforming service is 25/20 Cr/Ni with the generic reference HK40.

November/December 1995 Inspectioneering Journal
By Richard S. Boswell, P.E. at Stress Engineering Services, Inc.

Evaluations of aged and critical service vessels such as FCCU's and Delayed Cokers have been aided by the addition of two physical measurements referred to as structural characterizations. These are placed in perspective with the classic description provided by John Reynolds in his presentation of a multidisciplinary team effort in Fitness for Service (FFS) evaluations.
