About the course
The occurrence of hydrogen embrittlement is a much-researched phenomenon, known to cause mechanical property degradation and catastrophic failures. This form of cracking is especially detrimental and often observed in oil country tubular goods (OCTG) which are subjected to sour gas. Consequently, the significance of HIC is most appreciated by oil companies at various stages of oil extraction, transportation, and storage.
In this training course participants will be taught the fundamentals of hydrogen embrittlement, also known as Hydrogen Induced Cracking (HIC), and gain a comprehensive understanding of the causes, mechanisms, and effects of hydrogen embrittlement in low-strength steels. The core focus is to teach how to identify factors influencing HIC susceptibility and learn about the various factors, including material composition, processing conditions, and environmental factors, that contribute to the susceptibility of low-strength steels to hydrogen-induced cracking.
The course addresses a significant concern in various industries and processes, equiPiping professionals with the knowledge and skills to prevent and mitigate HIC in low-strength steels. Thereby ensuring safety, reliability, and cost-effectiveness in the use of these materials. Participants will gain in-depth knowledge of the HIC phenomena and applicable risk assessments, and learn practical approaches to ensure the safety and reliability of low-strength steel structures and components. The course combines theoretical concepts with real-world case studies and examples.
The course consists of 12hr of live sessions with the instructor. All training content is provided through your EngineeringTrainer account.
