ASME PTB-3-2010 pdf download.ASME Section VIII - Division 2 Example Problem Manual.
1.1 Introduction ASME B&PV Code, Section VIII, Division 2 contains mandatory requirements, specific prohibitions, and non-mandatory guidance for the design, materials, fabrication, examination, inspection, testing, and certification of pressure vessels and their associated pressure relief devices. The 2007 edition of the code has been re-written and reorganized, and incorporates the latest technologies for pressure vessel design.
1.2 Scope Example problems illustrating the use of the design-by-rule and design-by-analysis methods in ASME B&PV Code, Section VIII, Division 2 are provided in this document. Example problems are provided for all calculation procedures in both SI and US Customary units.
1.3 Organization and Use An introduction to the example problems in this document is described in Part 2 of this document. The remaining Parts of this document contain the example problems. The Parts 3, 4, and 5 in this document coincide with the Parts 3, 4 and 5 in the ASME B&PV Code, Section VIII, Division 2. For example, example problems illustrating the design-by-rule calculations contained in Part 4 of Section VIII, Division 2 are provided in Part 4 of this document. All paragraph references are to the ASME B&PV Code, Section VIII, Division 2 2007 with the 2009 Addenda [1]. The example problems in this manual follow the calculation procedures in ASME B&PV Code, Section VIII, Division 2. It is recommended that users of this manual obtain a copy of ASME PTB-1- 2009 [2] that contains criteria and commentary on the use of the design rules. It should be noted that VIII-2 permits the use of API 579-1/ASME FFS-1 [3] for some calculation procedures. When reviewing certain example problems in this manual, it is recommended that users obtain a copy of this standard.

4.2 Welded Joints 4.2.1 Example Problem E4.2.1 – Nondestructive Examination Requirement for Vessel Design A significant change to the new VIII-2 is the introduction of rules for the examination of welded joints, which introduce Examination Groups. These Examination Groups permit partial radiography and also require surface examination as part of the nondestructive examination (NDE) requirements. Part 7, paragraph 7.4.2 and Table 7.1 of VIII-2 define the different Examination Groups assigned to welded joints based on the manufacturing complexity of the material group, the maximum thickness, the welding process, and the selected joint efficiency. Once the Examination Group is selected, Table 7.2 provides the required NDE, joint category designation, joint efficiency, and acceptable joint types.ASME PTB-3 pdf download.
