Introduction
Subject matter experts (SMEs) are individuals who possess and demonstrate a high degree of specialized knowledge, skills, and experience in a particular technical domain, process, or technology. They are recognized as authoritative sources within their field, providing guidance, insights, and informed decision-making. Their expertise is characterized by a combination of up-to-date theoretical understanding and extensive practical experience, contributing significantly to the success of complex projects and initiatives. However, one critical facet distinguishes SMEs who make a significant impact: their willingness to challenge the status quo. This attribute is particularly important when developing codes and standards, as progress in this realm comes from pushing technological boundaries, documenting the basis for change, and shifting existing beliefs to drive industry advancements and effect meaningful change. Notable examples of such SMEs in the materials field include Dr. Martin Prager, Dr. Carl Lundin, and Dr. Howard Voorhees, whose work has significantly influenced the refining, petrochemical, chemical, fossil utility, and nuclear industries. This article explores the role of SMEs in shaping technological advancements and industry standards, focusing on their ability to challenge and evolve the status quo.
Dr. Martin Prager
Dr. Martin Prager's distinguished career as an executive director of prominent industry councils, including the Welding Research Council (WRC), the Materials Properties Council (MPC), and the Pressure Vessel Research Council (PVRC), has left an indelible mark on the materials and pressure vessel industries. Under his guidance, over 300 WRC Bulletins and other technical journals were published, covering a wide range of topics such as metallurgy, welding and weldability, design of welded components, and fitness-for-service assessments of pressure vessels, piping, pipelines, and tankage.
ASME and API Technical Contributions
Dr. Prager's significant contributions to the development of ASME and API Codes and Standards, as well as API technical reports, recommended practices, and standards, have advanced the field and improved industry practices. Among his notable accomplishments is the development of statistical methods for establishing allowable stresses in the creep range and the management of ASME allowable stress tables for the Pressure Vessel and Boiler Codes and the ASME B31 piping codes.
