Failure and Damage Mechanisms of Pressurized Equipment

Classroom Training

ASME and API codes are commonly referred to for the design, fabrication, inspection, and testing of pressurized equipment. Failure and damage mechanisms during service are however generally not addressed in these codes. Understanding and determining the causes of failure or degradation is essential when conducting a general inspection, fitness-for-service (FFS) assessment or risk-based-inspection (RBI) of an equipment or plant.

As determination of the cause of failures/degradation can be quite complex due to widely varying material/environmental condition interactions in most plants, API Recommended Practice 571 was published to provide information and general guidelines to assist inspection personnel and engineers in identifying likely causes of damage, as well as to introduce the concepts of service-induced deterioration and failure modes.

While API 571 does serve its purpose well, this training course aims to provide participants with deeper understanding of the failure/damage mechanisms through case studies, comprehensive presentation of metallurgical/scientific evidence and explanation of the fundamentals behind the respective mechanisms. The course also introduces the concepts of metallurgical failure analysis, which would help participants on diagnosing failure and damage mechanisms.

Objectives:

The training provides participants with:

Basic concepts in metallurgy
Overview of failure analysis and the techniques of diagnosing failure modes and damage mechanisms
Understanding of general damage mechanisms for all industries
Understanding of damage mechanisms in refining/petrochemical industries (for 3rdday course). Integrationof theoretical and practical knowledge through case studies.
Ability to recognize and evaluate different failure/damage mechanisms and their implicationson service life.
