This corrosion assessment module provides a comprehensive introduction to evaluating corrosion in pipelines, with a focus on the ASME B31G standard.
Corrosion can affect both external and internal surfaces of oil and gas pipelines, often caused by environmental conditions or the corrosive nature of the substances they carry, such as natural gas, crude oil, and other products.
While not all pipeline corrosion instances demand immediate repair, conducting a detailed pipeline integrity assessment—using methods like the ASME B31G standard—is crucial.
This standard, developed by the American Society of Mechanical Engineers, helps operators determine the severity of corrosion and decide if and when pipeline repair or pipeline maintenance is necessary. Implementing this standard ensures safe and efficient operation, extending the lifespan of the pipeline and minimizing the risk of failures or leaks.

Cheryl Argent has 19 years of experience in the oil and gas industry. She holds a bachelor's degree in Mathematics and Statistics and a master's degree in Pipeline Engineering. Early in her career, Cheryl specialized in risk-based inspection for offshore platforms and onshore facilities before transitioning to pipeline integrity assessments. She has a strong interest in pipeline corrosion mechanisms, corrosion growth behaviour, and maximizing insights from in-line inspection data. In recent years, Cheryl has focused on training and development, overseeing ROSEN's internal training and qualification program for Integrity Engineers.
Bruce Nestleroth has been working in the nondestructive testing field since the 1980s with a primary concentration on inspection technology to assess pipelines for potential defects. After earning his Ph.D. at Drexel University, he worked at Battelle for 26 years and then at Kiefner for seven years. After a short retirement, he joined ROSEN as an Expert in 2021, with a primary focus on education, and was based in Columbus Ohio, USA. Dr. Nestleroth studied the capability and advanced the application of magnetic flux leakage, eddy current, ultrasonic, and electromagnetic acoustic transducer in in-line inspection technology. Dr. Nestleroth has taught training courses and workshops on pipeline inspection technology and defect assessments since 1995. He has served many American Petroleum Institute (API) committees to develop technical standards for the pipeline industry.
