The Fourth Edition of the CASTI Guidebook to ASME B31.3 - Process Piping covers the new 2004 ASME B31.3 code book that was released in June 2005. This edition of ASME B31.3 contains many significant technical changes which include:

ü      new weld joint strength reduction factors based on consideration of creep effects

ü      alternative allowable stress for occasional loading of components at elevated temperatures

ü      newly revised stress range factors, f, for flexibility/fatigue analysis with specific limitations

ü      the addition of alternative rules for flexibility analysis (Appendix P)

ü      the addition of piping stress analysis examples (Appendix S)

ü      changes to the rules limiting vocalization for pipe bends under certain conditions

ü      thermoplastics permitted in above ground flammable fluid service under specific conditions and limitations

ü      new specific design requirements for expansion joint hardware (Appendix X)

ü      new example added to Appendix V dealing with method for assessing the effect of short term variations at elevated temperatures

ü      new Code Interpretation covering the issues of repair and replacement

ü      new Code Interpretation covering flexibility analysis temperature

The Guidebook is filled with many practical example calculations for piping design and analysis in both US customary and Metric units.

The intent of this Guidebook is to provide the users of ASME B31.3 with a better understanding of the ASME B31.3 Code. It is written by piping code experts with long time ASME B31.3 code committee and international engineering experience. Going far beyond the literary words of the Code, the authors of this Guidebook explain specific Code paragraphs and related ASME Code Interpretations to provide guidance where a close study of the Code, on its own, may not produce a clear conclusion.
