Full title and description

ASME PTB-3:2022 — Section VIII, Division 2 Example Problem Manual. A companion publication to the ASME Boiler & Pressure Vessel Code (BPVC), Section VIII, Division 2, presenting worked example problems and illustrative design calculations used to apply the Division 2 rules for pressure-vessel design, fabrication, examination, testing and certification.

Abstract

This manual contains a comprehensive set of worked example problems that demonstrate application of the ASME BPVC Section VIII, Division 2 design rules. It is intended to help engineers and code users interpret and apply Division 2 requirements by showing step‑by‑step calculations, assumptions, and commentary for common and complex pressure‑vessel design scenarios. The examples cover material selection, stress analysis, component design (shells, heads, nozzles), weld and fabrication considerations, inspection and testing topics, and certification-related calculations.

• Number of pages: 540 pages (typical published pagination for the 2022 edition).

Scope

The manual provides illustrative, non‑mandatory example problems that apply the mandatory requirements and design procedures of ASME BPVC Section VIII, Division 2. Examples are provided to show how to perform design calculations and checks called for by Division 2, including allowable stresses, stress classification and evaluation, material and thickness calculations, nozzle and head design, load cases, fatigue and cyclic considerations, and examples of inspection and testing calculations. It is not a substitute for the Code text but serves as a practical guide to using the Division 2 provisions.

Key topics and requirements

• Worked example calculations for Division 2 design formulas and procedures.
• Stress evaluation and classification methods used in Division 2.
• Material selection and allowable stress use in sample problems.
• Design and verification of shells, heads, nozzles and attachments.
• Considerations for cyclic loading, fatigue, and high‑temperature design where applicable.
• Welding, fabrication and nondestructive examination (NDE) examples tied to design outcomes.
• Inspection, testing, and certification example calculations and documentation practices.

Typical use and users

Primary users are pressure‑vessel designers, mechanical engineers, code users, fabricators, inspectors, and technical training instructors who need practical worked examples to apply ASME BPVC Section VIII, Division 2. The manual is also commonly used as a reference for code interpretation discussions, engineering review, and exam/study preparation for personnel working with Division 2 designs.
