Material Selection for Sour Service

Material selection for sour service will be simplified for the purchaser, end user or field inspector. Attendees will gain an understanding of the general principles for selection of cracking-resistant materials used in H2S-containing environments in the oil and gas industry. This knowledge can be applied to address the potentially costly and sudden failure of equipment that could lead to significant risk to the health and safety of plant personnel and the public. Learn the history of the approaches to sour service material selection of common materials in industry standards such as CSA Z662, ASME codes, NACE MR0175/ISO 15156 and NACE MR0103. Test methods and manufacturing practices used to assist in avoidance of cracking failures will be discussed. These include hardness testing, TM0177, and TM0284.

Topics
  • Pertinent damage mechanisms – sulphide stress cracking, stress corrosion cracking, hydrogen-induced cracking, step-wise cracking, and stress-oriented hydrogen induced cracking, etc.
  • Definition of crack-causing environments
  • History of MR0175
  • Practical use of MR0175
  • NACE MR0103
  • CSA Z662 and ASME Code approaches to crack prevention in H2S environments
  • Pertinent regulatory requirements
  • Brief introduction to weld ability of common steels for wet H2S service
  • The importance of proper welding or joining
  • Carbon equivalence formulas
  • Common heat treatments
  • Commonly acceptable materials for H2S environments
  • Hardness tests, TM0177 tests, TM0288 tests
  • Purchasing materials for sour service
