ASME PTB-1-2009 pdf download.ASME Section VIII – Division 2 Criteria and Commentary.
The Equity Engineering Group, Inc. contributed significant resources to the development of the Criteria and Commentary. In particular: Jeffery Brubaker provided assistance in the documentation of the toughness rules of Part 3; Jeremy Staats reviewed the work of Pellini and developed the documentation for operation on the lower-shelf; James Sowinski developed the background material for conical transition without knuckles or flares in Part 4; Dr. Warren Brown provided background information on both current and future directions for the flange design rules; Dr. Zhenning Cao developed the theory and documentation for the stress analysis of conical transitions with knuckles and flares in Part 4 as well as the overview of the Structural Stress and Master Curve approach for the fatigue evaluation of welds in Part 5; Joel Andreani provided background material covering the development of the load factors in Part 5; and Robert Brown assisted in the development of Part 5. A special commendation for technology development for the new Section VIII, Division 2 is extended to Dr. Martin Prager of MPC and WRC. Dr. Prager developed many key technology features of the Code including a new universal stress-strain curve that is used for Design-By-Analysis in Part 5 and also for design for external pressure. This stress-strain curve model replaces the A-B Charts in Section II Part D. Dr. Prager developed the material models used in conjunction with the API 579- 1/ASME FFS-1 FAD assessment technology for the evaluation of crack-like flaws to develop the new toughness rules of Part 3 that is based on a 20 ft-lb criteria similar to European practice. He also developed the technology for the new strain-based Protection Against Local Failure in Part 5. Together with Dr. Pingsha Dong, Dr. Prager was instrumental in introducing and incorporating the new Structural Stress and Master Fatigue Curve approach for the evaluation of welded joints.
The paragraph numbering in the Criteria and Commentary matches that of VIII-2. Figure and tables are numbered consecutively within each part of this document. If the figure or table is from VIII-2, then the VIII-2 figure or table number is provided in parenthesis. Rules for referencing paragraphs, tables and figures are described below. • References to paragraphs, tables and figures within the Criteria and Commentary are made directly. For example, a reference to paragraph 4.2 in this document would be designated as paragraph 4.2, a reference to Table 3.4 in this document would be designated as Table 3.4, and a reference to Figure 5.1 in this document would be designated as Figure 5.1. • References to paragraphs, tables and figures in VIII-2 are preceded by the applicable part number. For example, a reference to paragraph 4.2 in Part 4 of VIII-2 would be designated in this document as Part 4, paragraph 4.2, a reference to Table 3.4 in Part 3 of VIII-2 would be designated as Part 3, Table 3.4, and a reference to Figure 5.1 of Part 5 of VIII-2 would be designated Part 5, Figure 5.1. • References to paragraphs, tables and figures in VIII-1, Old VIII-2, or VIII-2 are preceded by this code designation. For example, a reference to paragraph UW-26(d) in VIII-1 would be designated in this document as VIII-1, UW-26(d), a reference to Table UW-12 or VIII-1 would be designated as VIII-1, Table UW-12, and a reference to Figure UW-13.1 of VIII-1 would be designated VIII-1, Figure UW-13.1. • References to other sections of the ASME B&PV Code are made directly. For example a reference to the ASME B&PC Code, Section II, Part D would be designated as Section II, Part D, and a reference to Article 23 of Section V would be designated as Section V, Article 23. The term Section VIII Committee used in this document refers to the Section VIII Standards Committee of the ASME B&PV Code.
