The American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code (BPVC) is the definitive global standard for the design, fabrication, and inspection of boilers and pressure vessels. Within this framework, Section II plays a foundational role by establishing the material specifications necessary to ensure structural integrity and public safety. Specifically, Section II Part A focuses exclusively on ferrous materials—metals that contain iron, such as carbon steel, stainless steel, and cast iron.
Each specification (designated with an "SA" number, e.g., SA-516) details the material's:
Using the correct 2019 PDF version of Section II Part A ensures that all materials used in construction meet the mandated safety factors defined in the 2019 ASME Code updates.
Specifications for high-strength bolts, studs, and nuts used in flanged joints (e.g., SA-193, SA-194). : Find the material specification and grade in
The purchasing department orders the steel plates specifying compliance with "ASME Section II Part A, 2019 Edition, SA-516 Grade 70."
The 2019 edition of ASME BPVC Section II Part A includes the following:
