ASME BPVC Section VIII Division 2, also known as "Pressure Vessels - Alternative Rules," provides alternative rules for the design, fabrication, inspection, and testing of pressure vessels. This division is intended for vessels that are designed for high-pressure and high-temperature applications, such as those used in the petrochemical, power generation, and chemical processing industries.
The ASME BPVC Section VIII Division 2 PDF can be accessed through the ASME website or through various online databases and libraries. It is essential to ensure that the PDF is obtained from a reputable source and is up-to-date with the latest revisions and addenda.
: Division 2 offers a lower factor of safety compared to Division 1. Specifically, Class 1 vessels use a factor of 3.0, and Class 2 vessels use 2.4 on ultimate tensile strength (UTS).
Pro tip: Print the "Design Procedure Checklist" from Part 5, Annex 5.A.2 and attach it to your design notebook.
: It uses the Von Mises or Maximum Distortion Energy Theory to determine material limits, whereas Division 1 uses Maximum Principal Stress.
