The ASME Boiler and Pressure Vessel Code (BPVC) is a comprehensive standard that regulates the design, construction, and operation of boilers and pressure vessels5. It is developed and maintained by the American Society of Mechanical Engineers (ASME) and serves as the largest technical resource in this field

The most recent update to the ASME BPVC was released on July 1, 2023

The ASME BPVC is updated and released every two years

The ASME BPVC consists of several sections, including:

• Section II: Materials
• Section III: Rules for Construction of Nuclear Facility Components
• Section V: Nondestructive Examination
• Section VIII: Rules for Construction of Pressure Vessels
• Section IX: Welding, Brazing, and Fusing Qualifications

The 2023 edition includes various updates and enhancements, such as:
