ABOUT THE AUTHOR
,'/
(
Dr. Becht is a recognized authority in pressure vessels, piping, expansion joints, and elevated temperature
design. He is President of Becht Engineering Co. Inc, a consulting engineering company that provides both
process and equipment engineering services as well as project and turnaround services for the process and
power industries; President of Becht Engineering Canada Ltd.; President of Helidex, LLC; and Director of
Sonomatic Ltd. (also dba Becht Sonomatic in North America) an NDE company that provides advanced
ultrasonic imaging equipment and services. He has performed numerous expert troubleshooting and failure
investigations, design reviews and construction inspections for capital projects into the billion dollar range,
and consulting to manufacturers on design, development and code compliance for new and existing equip
ment. He was previously with Energy Systems Group, Rockwell International and Exxon Research and
Engineering where he was a pressure equipment specialist.
Dr. Becht is Chair of the ASME B31.3, Process Piping Committee; Chair (founding) of the Post
Construction Subcommittee on Repair and Testing (PCC), and member of other ASME Committees
including the Post Construction Standards Committee (past Chair); Post Construction Executive Com
mittee (past Chair); B&PV Code Subcommittee on Transport Tanks; B&PV Code Subgroup on Elevated
Temperature Design (past Chair); B31 Code for Pressure Piping Standards Committee; B31 Mechanical
Design Committee; B31 Executive Committee; and is a past member of the Board on Pressure Technol
ogy Codes and Standards; the B&PV Code Subcommittee on Design; and the B&PV Code TG on Class 1
Expansion Joints for liquid metal service. He is a member of ASTM Committee F-I7, Plastic Piping
Systems Main Committee; and the ASME PVP Division, Design and Analysis Committee.
Dr. Becht has developed and introduced many new concepts into ASME B31.3, including weld joint
strength reduction factors, alternative rules for flexibility analysis (Appendix P), new stress limits for
occasional loads at elevated temperatures, and extension off factors to unlimited numbers of cycles.
He received a PhD from Memorial University in Mechanical Engineering (dissertation: Behavior of
Bellows), a MS from Stanford University in Structural Engineering and BSCE from Union College,
New York. Chuck is a licensed professional engineer in 16 states and provinces, an ASME Fellow since
1996, recipient of the ASME Dedicated Service Award in 2001, and has more than 60 publications and
five patents.

ACKNOWLEDGEMENTS
Thanks to my assistant, Mickey Smajda, who helped in the preparation of this book, to the ASME
publications staff who were helpful, and Fred Tatar and Bob Sims who reviewed Chapter 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
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 taughl that have, at times, asked difficult
questions, that have greatly enriched this book.

WHAT'S NEW IN THE
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 major additions relate to new Code requirements included in the
2006 and 2008 editions of ASME B31.3. These include the following.
I. New requirements for weld joint strength reduction factors, in Section 3.4.
2. Changes to Section VITI references to be consistent with the rewritten Code, in Section 4.15, 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 specific equation for evaluation of longitudinal
stresses due to sustained loads, in 6.2.
6. New requirements 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 advanced 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.
II. Revised hydrostatic test requirements, in Section 14.2.
12. Addition of a Code Case for testing jacketed piping, in Section 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 covered. 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 4.11.
5. Discussion of ASME Research on stress limits for occasional loads at elevated temperatures, in Sec
tion 6.3.
