Piping Corrosion Mechanisms: CUI, MIC, Erosion and Under-Deposit Corrosion
| 30 Mar. – 03 Apr. 2026, Abu Dhabi | 27 – 31 July 2026, Abu Dhabi |
COURSE OVERVIEW:
The meaning of piping corrosion mechanisms refers to the various chemical, electrochemical, and mechanical processes that cause the deterioration of piping materials in industrial environments. This course provides a deep dive into the four most prevalent and damaging threats to piping integrity: Corrosion Under Insulation (CUI), Microbiologically Influenced Corrosion (MIC), Erosion-Corrosion, and Under-Deposit Corrosion. By understanding the root causes and environmental triggers of these mechanisms, participants will be better equipped to design effective prevention and monitoring strategies that ensure the long-term reliability of plant assets.
The scope of the training encompasses the metallurgical and environmental factors that drive localized attack in both carbon steel and stainless-steel piping. Participants will examine the specific temperature ranges where CUI is most aggressive, the biological conditions that promote MIC in stagnant lines, and the fluid dynamics that lead to erosion-corrosion in high-velocity systems. The course emphasizes the transition from reactive repair to proactive management, utilizing the guidelines provided in API 571 (Damage Mechanisms Affecting Fixed Equipment in the Refining Industry).
The coverage of the program is organized into ten modules that follow the lifecycle of corrosion management, from identification and measurement to mitigation and repair. Key topics include the use of advanced NDT for detecting hidden damage, the selection of protective coatings and insulation systems, and the application of chemical biocides and inhibitors. The course also addresses the role of design in preventing corrosion, such as the elimination of "dead legs" and the optimization of piping layouts to minimize turbulence. The program concludes with a workshop on root cause analysis of real-world piping failures.
COURSE OBJECTIVES:
After completion of this course, the participants will be able to:
- Identify the primary corrosion mechanisms affecting process piping.
- Explain the environmental drivers of Corrosion Under Insulation (CUI).
- Detect and characterize Microbiologically Influenced Corrosion (MIC).
- Analyze the factors contributing to Erosion-Corrosion and Cavitation.
- Understand the mechanisms of Under-Deposit Corrosion and Pitting.
- Utilize the API 571 standard for damage mechanism identification.
- Select appropriate NDT methods for detecting localized corrosion.
- Implement effective coating and insulation strategies to mitigate CUI.
- Design piping systems to minimize stagnant zones and "dead legs."
- Apply chemical treatment programs to control MIC and internal scaling.
- Evaluate the effectiveness of corrosion monitoring tools (coupons and probes).
- Perform a Root Cause Analysis (RCA) on a piping corrosion failure.
TARGET AUDIENCE:
This course is intended for Corrosion Engineers, Materials Specialists, Piping Inspectors, Maintenance Engineers, and Plant Integrity Personnel.
TRAINING COURSE METHODOLOGY:
A highly interactive combination of lectures, discussion sessions, and case studies will be employed to maximize the transfer of information, knowledge, and experience. The course will be intensive, practical, and highly interactive. The sessions will start by raising the most relevant questions and motivating everybody to find the right answers. The attendants will also be encouraged to raise more of their questions and to share in developing the right answers using their analysis and experience. There will also be some indoor experiential activities to enhance the learning experience. Course material will be provided in PowerPoint, with necessary animations, learning videos, and general discussions.
The course participants shall be evaluated before, during, and at the end of the course.
COURSE CERTIFICATE:
National Consultant Centre for Training LLC (NCC) will issue an Attendance Certificate to all participants completing a minimum of 80% of the total attendance time requirement.
