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. It can be applied to help to avoid costly corrosion damage. This will be achieved by studying basic steel metallurgy, H2S related damage mechanisms, hardness test methods, steel standards and applying this fundamental knowledge to understanding the intent of NACE MR0175/ISO 15156 and MR0103. To assist with these objectives, an introduction to H2S-environment cracking test methods TM0177 and TM0284 will be studied. Topics: General Introduction - Introduction to NACE Material Requirements Standards - History of MR0175 development - Overview of MR0175/ISO 15156 Parts 1, 2, and 3, MR0103, TM0177, TM0284, and how they work together. Introduction to Carbon and Alloy Steel Metallurgy - Introduction to carbon steel metallurgy - Using the Fe-Fe3C phase diagram in practical terms - Using continuous cooling transformation diagrams to predict undesirable steel conditions for sour service - Common heat treatments for carbon and alloy steels - Classification of steels - UNS, ASTM, ASME, SAE (AISI), API, EN, and how they are used within NACE MR0175/ISO 15156 - Detailed discussion of the misnomers and slang terms used to described steels - Review of several commonly used ASTM steel standards - General introduction to the weldability of carbon and alloy steels for wet H2S service: - Defining the weld in metallurgical terms - Understanding the weld heat affected zones (HAZs) - Use of carbon equivalence formulas Introduction to Stainless Steel Metallurgy - Types and classification of stainless steels - General corrosion resistance of stainless steels (advantages and disadvantages) - General introduction to the weldability of stainless steels for wet H2S service H2S Related Damage Mechanisms - introduction to H2S related damage mechanisms: blistering, hydrogen embrittlement, sulfide stress cracking, hydrogen induced cracking, stress oriented hydrogen induced cracking, stepwise cracking, soft zone cracking, and service specific related damage such as amine stress corrosion cracking and sour water corrosion - description of wet H2S related damage, affected materials, critical factors, affected units or equipment, appearance or morphology of damage, prevention/mitigation, inspection and monitoring Hardness Test Methods and Related ASTM and ISO Standards - Bench hardness testing: - ASTM E 10 and ISO 6506-1 (Brinell) - ASTM E 18 and ISO 6508-1 (Rockwell) - ASTM E 92 and ISO 6507-1 (Vickers) - ASTM E 110 (Portable Hardness Testers) - ASTM E384 (Microindentation) - Portable hardness testing: - A 833 (Telebrineller) - A 956 (Leeb, Equotip, others) - A 1038 (Microdur - MIC) - Converting hardness test values to other scales: ASTM E 140 and ASTM A 370 NACE MR0175/ISO 15156 Part 1 - Overview of Part 1 - General Principles for Selection of Cracking-Resistant Materials - Evaluation of definition of service conditions - Pre-qualified materials NACE MR0175/ISO 15156 Part 2 - Qualification and selection of carbon and alloy steels for sour service: - defining sour service environment (H2S partial pressure vs. pH) - regions of environmental sensitivity (Figure 1 in MR0175/ISO 15156 Part 2) - Determination of H2S partial pressure and pH (Annex C and D) - Overview of Annex A - SSC-resistant carbon and alloy steels - maximum acceptable hardness values - applications to specific product forms (pipe, plate, fittings, bolting, etc.) - Purchasing Materials for Sour Service - Information to be supplied for material purchasing (Part 2 Annex E) - Material test reports (MTRs) - what they really mean and how they should be used to qualify and purchase steels within MR0175/ISO 15156 NACE MR0175/ISO 15156 Part 3 - Overview of Part 3 - cracking resistance of CRAs - qualification and selection of CRAs - explanation of PREN - material purchasing NACE Test Methods for Sour Service - Overview of NACE TM0177 and TM0284 - SCC laboratory testing for sour service (Part 2 Tables B.1, B.2, and B.3) - Example test reports and applications of both test methods will be discussed CSA and API Codes - Review of sour service requirements of CSA Z662, API 5CT, 6A and 6D specifications NACE MR0103 - Roadmap to MR0103 (Table 1) - Carbon, alloy, and stainless steel material requirements, including P-No. hardness - Nonferrous material requirements - Fabrication requirements (welding, cladding, stamping, threading) - Bolting requirements - Plating, coating and diffusion processes - Special component requirements (bearings, springs, instrumentation, etc.) - Valve requirements - Compressor and pump requirements Limitations of MR0175/ISO 15156 and MR0103 - Discussion of why hardness testing, laboratory testing, and NACE MR0175/ISO 15156 may not be sufficient to predict suitable application of materials for the intended sour service conditions Interpretations: During the course, regular references to published NACE MR0175/ISO 15156 and MR0103 interpretations will be discussed in detail to better understand the intent of the document. Problem Solving Workshops: The class will be divided into teams and given specific assignments to work with MR0175/ISO 15156. These exercises will provide each participant with practical working knowledge of MR0175/ISO 15156, under the guidance of the instructor's direction. Required Code Documents: All participants must bring NACE MR0175/ISO 15156 and MR0103 to this class. A course notebook will be provided to all participants by CASTI. 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. Accreditation: Each participant will receive a certificate with 3.2 Continuing Education Units accredited by the International Association of Continuing Education and Training (IACET). |
