16、pter 17.Thanks also to Bill Short who encouraged me to join the ASME B31.3 Code Committee in 1986, Sam Zamrik who encouraged me to teach a half-day tutorial on ASME B31.3 at the ASME Pressure Vessel and Piping Conference in 1992, and Chris Ziu who sponsored a series of three-day courses I taught on
17、ASME B31.3, which, in turn, led to this book.And to my colleagues on the ASME B31.3 Code Committee, with whom I have had many interesting discussions over the years, and the students in the courses I have taught that have, at times, asked diffi cult questions, that have greatly enriched this book.ix
18、WHATS NEW IN THE 2008 EDITION OF THIS BOOK?I felt it would be useful to the reader to summarize changes, in particular for those that may have spent the time to already read through the 2004 edition of this book. This is not a complete summary of changes, but provides most of the major changes. The
19、major additions relate to new Code requirements included in the 2006 and 2008 editions of ASME B31.3. These include the following.1. New requirements for weld joint strength reduction factors, in Section 3.4.2. Changes to Section VIII references to be consistent with the rewritten Code, in Section 4
20、.15, 9.3, Insert 9.2 and 17.6.3. Addition of requirement for valve stem retention, in Section 5.2.4. Update on various standards, in Chapter 5.5. Discussion of Code Case 178, which provides a specifi c equation for evaluation of longitudinal stresses due to sustained loads, in 6.2.6. New requirement
21、s for design of supports, in Section 9.3.7. Replacement for Table 12.2 with the revised version from the 2006 edition.8. Discussion of Code text added to clarify the intent of some progressive examination requirements, in Section 13.2.9. Addition of Code Case 181 to provide acceptance criteria for a
22、dvanced ultrasonic techniques that size defects, in Section 13.3.10. Additional requirements and discussion of subassemblies that have been previously tested, in Sec-tion 14.1.11. Revised hydrostatic test requirements, in Section 14.2.12. Addition of a Code Case for testing jacketed piping, in Secti
23、on 14.7.13. Changes to the pressure design equations for high pressure piping, in Section 17.3.14. Coverage of use of listed materials to other editions, in Section 17.7.15. Addition of leak test alternatives for high pressure piping, in Section 17.10.In addition, a few additional topics were covere
24、d. These include the following.1. Addition of the photo taken at the 125th meeting of the ASME B31.3 Section Committee.2. Addition of new Task Group H in the committee, in Section 1.6.3. Additional discussion of requirements for Listed Components, in Section 2.3.4. Mention of Appendix L, in Section
25、4.11.5. Discussion of ASME Research on stress limits for occasional loads at elevated temperatures, in Sec-tion 6.3.x Whats New in the 2008 Edition of This Book? 6. Mention of new considerations with respect to fatigue design rules, in Section 7.1.7. Mention of examples added to Appendix S in the 20
26、06 edition, in Section 8.1.8. Discussion of branch connection attachment welds, in Section 12.12.9. Reference to procedures to calculate stored energy and safe distances for pneumatic tests, in Section 14.3.10. Component pressure-temperature ratings in Appendix I were updated in accordance with chan
27、ges in the subject standards.Committee members and visitors at the 125th meeting of the ASME B31.3 Section CommitteeRow 1 (Left to Right): Melo, Cynthia; Kadakia, Dixit; Engle, Rex Ch IRG and SG C; Meyer, Jimmy Vice Chair; Becht, Charles Chair; Xiaoli (Shelly) Tang; Truong, Quy; Medvick, Richard; Na
