Objectives

To gain an understanding of general principles for selection of cracking-resistant materials used in H2S-containing environments in oil and gas production where the failure of such equipment could pose a risk to the health and safety of the public and personnel or to the environment as described in NACE MR0175/ISO 15156 and for refineries as described in NACE MR0103. This will be achieved by clarifying the responsibilities of the equipment user, manufacturer, and supplier as defined in NACE MR0175/ISO 15156 and NACE MR0103 aided by studying basic steel metallurgy, H2S related damage mechanisms, hardness test methods, steel standards. To assist with these objectives, a brief introduction to H2S-environment cracking test methods NACE TM0177 and TM0284 will be covered.

Accreditation

Each participant will receive a certificate with 3.2 Continuing Education Units accredited by the International Association of Continuing Education and Training (IACET).

Who Should Attend

Engineers, testing lab technologists and technicians, inspectors, equipment designers, steel manufacturers, distributors, and maintenance personnel who are involved in designing, fabricating, manufacturing, supplying, operating, maintaining, repairing, and inspecting oil field and refinery equipment in sour service by using NACE MR0175/ISO 15156 and MR0103. This course will assist personnel performing API 579 and API 581 evaluations.
