Case Studies

A study of the level of deterioration on a catalytic reformer support structure, the challenges involved, the solutions presented, and the aggressive schedule that was required to complete the project.

This study found that a machine learning model was able to predict degradation rates for a hydrocracker unit more accurately and with a smaller margin of error compared to current industry practices.

The influence of sensitization on creep response of hydrocracker feed fractionator fired heater tubes made of AISI Type 347 stabilized steel after service exposure of around 20 years is investigated.

Applying advanced statistical analysis methods will provide owner/users with a RAGAGEP-accepted method for analyzing corrosion monitoring data while also integrating the latest improvements in inspection capabilities.

This article describes HTHA predictive modeling advances that are designed to demonstrate a direct integration with inspection such that modeling and inspection can be leveraged together in a way never done before.

The application of a detailed design-by-analysis method using ASME Sec-VIII Div-2 confirms field-observed ratcheting and fatigue type failures in the tubesheet due to the complex cyclical thermal-mechanical loading encountered during operation.

Traditional line interventions either utilize a single isolation point or are utilized in conjunction with bypass lines. A double block and bleed (DBB) replaces the need for using three separate line interventions to perform the same function.

A finite element analysis (FEA) was performed on five different models of varying configurations as an approach to establish best practices in the choice of the most appropriate factor of safety, depending on the type of metal loss.

A historical review into the integrity of reformer furnaces since commissioning is discussed in this case study, along with other technical and engineering challenges, and the efforts to overcome them.

Establishing a proactive touch point corrosion integrity management program using engineered on-stream line lifting is a safe and effective means of mitigating unplanned downtime and related safety and potential environmental hazards.

Condition monitoring optimization goes beyond traditional CML optimization, which is often limited in the breadth of analysis, or can overemphasize a subset of the overall objective.

This article presents two case studies that show how having a holistic approach, along with the right technology and experience, is essential to identifying smaller damage mechanisms like fretting in fired heater coils.

This article summarizes the fundamentals of wet H2S-related damage mechanisms, offers some practical inspection guidance, and reviews a notable industry failure caused by different forms of wet H2S damage.

This article discusses how composite materials can be used to mitigate light CUI damage and/or repair and restore structural strength to the affected piping system.

TEAM believes that quality inspections are the key to reliability. Our inspection crews are made up of specialty trained, experienced technicians who adhere to the highest quality standards. Our API 653 inspectors deliver thorough, reliable...

A risk management approach for relief valves should be able to determine the proper interval of maintenance events and the necessity of installing isolation valves, rupture discs, or 100% spare capacity.
