The ASME Boiler and Pressure Vessel Code establishes design, construction, and in-service inspection requirements for equipment operating above atmospheric pressure. Section VIII, Division 1 provides rules for construction of pressure vessels subject to internal or external pressure. Rules-based construction approach and acceptance criteria provide baseline assurance of equipment safe operation throughout design life.
Section XI governs in-service inspection and testing of nuclear power plant components, establishing mandatory inspection frequencies, methodologies, and acceptance criteria for maintaining nuclear facility safety. Section V establishes nondestructive examination procedures including ultrasonic testing, radiography, magnetic particle inspection, and liquid penetrant examination. NDT training programs maintain inspector familiarity with current Section V requirements.
ASME B31.1 governs power piping, including steam, condensate, and auxiliary systems in power generation facilities. B31.3 addresses process piping for petroleum refining, chemical, and pharmaceutical applications. B31.4 covers liquid transportation piping. B31.8 governs gas transmission pipelines. Each standard reflects unique operating conditions and failure mechanisms relevant to specific industries. NDT consulting services guide operators through applicable B31 code requirements.
ASME code development remains ongoing, with new editions published triennially and interpretations addressing code implementation questions. Staying current with code revisions ensures inspection programs comply with latest requirements and reflect industry experience with emerging failure mechanisms and improved methodologies.
