ASME Section VIII is a part of the ASME Boiler and Pressure Vessel Code (BPVC) that establishes standards for ensuring the safety and reliability of pressure vessels and boilers. It focuses on designing, constructing, inspecting, and certifying pressure vessels for various industries. ASME Section VIII ensures that pressure vessels can withstand internal pressure during operation without risking failure or leakage.

Manufacturers and designers need to follow the guidelines in ASME Section VIII to ensure their pressure vessels meet safety standards and can be operated with confidence. ASME Section VIII includes different divisions, such as Division 1 focuses on pressure vessel design and construction when the maximum allowable working pressure (MAWP) exceeds 15 psi, and Division 2 is applicable for pressure vessels with a maximum allowable working pressure (MAWP) equal to or less than 15,000 psi.

What Is ASME Section VIII Div. 1 Latest Edition Update?

According to IHS (Accuris), the 2023 edition of BPVC Section VIII, Division 1 introduces several key changes:

  1. Addition of paragraph UG-84(d)(3) clarifying impact test requirements for diffusion welding (DFW).
  2. Inclusion of paragraph UG-101(a)(5) for sharing proof testing reports between related manufacturers.
  3. Realignment and revision of Part UHX for consistency across heat exchanger types.
  4. Removal of Part UHX and Appendix 26, referencing Part 4.18 and 4.19 of Division 2 instead.
  5. Revision of “PRT” to “PRT VIII-1” designation throughout Section VIII, Division 1.

These updates aim to enhance clarity, consistency, and maintenance ease for pressure vessel design and fabrication.

What Is ASME Section VIII Div. 2 Latest Edition Update?

The 2023 edition of BPVC Section VIII, Division 2 includes the following key changes:

  1. Removal of Certifying Engineers for Class 2 Design-by-Rule (DBR) applications in Part 2, eliminating conflicts with international engineering registration requirements.
  2. Realignment and revision of Part 4.18 for consistency in heat exchanger design, with revised shell and channel coefficients based on the mean diameter.
  3. Addition of paragraph to assign a common joint category for tube-to-tube sheet welds.
  4. Complete rewrite of Paragraph 5.4 and introduction of Table 5.8 for protection against buckling.
  5. Revision of Paragraph and Table 5.10, providing a simplified method for screening components in cyclic service.
  6. Replacement of “PRT” with “PRT VIII-1” designation in Section VIII Division 2.

Quoting from IHS (Accuris) these changes improve consistency, align with international standards, and enhance the design and operation of pressure vessels.
