PREFACE TO THE FIFTH EDITIONThis edition continues to address the purpose of the previous editions to serve as a “Primer” to help the user weave through var- ied aspects of the ASME Codes and B31 Piping Codes, in addi- tion to a discussion of “The Criteria and Commentary on Select Aspects of ASME Boiler and Pressure Vessel and Piping Codes” of interest to “end users”. This publication has been revised in pro- viding all of the aspects of the previous editions, while updating to the current 2015 Codes and topics pertinent to 2017 B&PV Code. This book strives to be a comprehensive Companion Guide to the ASME Boiler and Pressure Vessel Code.This fully updated and revised fifth edition of this classic refer- ence work has addressed in 40 chapters ASME 2015 Boiler Pres- sure Vessel & Piping Codes and Standards, whereas the fourth edition addressed 2010 Code edition and 2011 addenda. In this entirely new publication experts discussed several ongoing issues even beyond 2015 Code edition. With entirely new and extensively re-written chapters, the Code Experts had in mind the use of this publication focused on the Addenda leading to the 2017 B&PV Code.This edition is available in a convenient two-volume format that focuses on all twelve sections of the ASME Code, and has two additional chapters covering the foreseeable new trends of the ASME boiler and pressure vessel codes. Several chapters are com- prehensively covered for this edition by 51 ASME B&PV Code experts, whose biographical data is included in the two volumes. An easy and quick to understand introduction in the front matter of each of the volumes succinctly explains what is elaborated in nearly 2000 pages of this 2-volume publication. Another feature of this publication is all users of Boiler and Pressure Vessel Code can identify from the index the 8000 individual Code related items. All of the 51 authors who contributed to 40 Chapters in this fifth edition considerably updated, revised or added to the content mat- ter covered in the fourth edition to address the current and future trends as well as dramatic changes in the industry in the ASME Boiler and Pressure Vessel Code Sections I through XII, and B31 Piping Codes that appear in Volume 2.Considering significant organizational changes are taking place in ASME that reflect the Industry’s demands both in USA and internationally, salient points of these have been captured in both the volumes by experts who have firsthand information about these. Volume 1 covers ASME Code Sections I through VII, and Volume 2 addresses ASME Code Sections VIII through XII. Con- tinuing and replacement authors have considerably updated the text, tables, and figures of the previous edition to be in line with the 2015 Code and topics pertinent to 2017 B&PV Code, bringing the insight knowledge of these experts in updating the previous edition. Fresh look has been provided by new authors, who in replacing previous contributors of few chapters, have provided added perspectives rendered in the earlier editions. In certain cases, the chapters had been entirely rewritten by replacement experts, with new titles but addressing the same topics while revising in its entirety and updating the information to the 2015 ASME Code Edition and topics pertinent to 2017 B&PV Code.Volume 1 has Chapter 1 covering “Section I—Introduction to Power Boilers” which has been authored by two new contributors, replacing the previous one, who revised this chapter considerably. Likewise Chapter 2 “Section VII—Recommended Guidelines for The Care Of Power Boilers” has a replacement author who has revised the chapter to a considerable extent. Chapter 3 for this edi- tion has been reorganized considering the changes in the applica- tion of material properties; accordingly Section 3.6 of Chapter 3 of the fourth edition, “Non-metallic Material used in Structural Applications”, has been dropped for the fifth edition and a consid- erably enlarged version of this topic is Chapter 12 for this edition. Considerable changes in this chapter, including graphics, have been updated and included in this edition.In volume 1 Chapters 4 through 7, 9 through 11, 14 and 16 of the fourth edition, have been updated and revised considerably by the continuing authors. Chapter 12 of this edition addresses new code material “Report on Committee on Nonmetallic Pressure Piping Systems, with its published requirements in three separate standards: NM-1 Thermoplastic Pressure Piping Systems; NM-2 FRP Pressure Piping Systems; and NM-3 Nonmetallic Materials (includes specifications and material properties similar to BPV Code Section II)” by code experts. Chapters 13, 18, 19 and 20 have new authors replacing the previous contributors and thereby con- siderably revising fourth edition content of these chapters. Chapter 15 covering Code Section III Division 2 has a replacement author in addition to other experts to address topics which had not been covered in the previous editions. Chapter 17 that covers “Division 5—High Temperature Reactors” authored by Code experts has considerable material from Chapter 12 of the fourth edition, who authored it in the fourth edition, included in this Chapter 17 of the current fifth edition. Chapter 8 has a replacement author for this fifth edition.Volume 2 has chapters addressing Code Sections VIII through XII with additional code material consistent with the current 2015 Code edition and topics pertinent to 2017 B&PV Code. Chapters 25, 27 and 38 have replacement authors in lieu of the fourth edition contributors, whereas in Chapter 22 a contributor has dropped out for this edition. Chapters 21 and 23 have a contributor in addi- tion to continuing authors, whereas Chapter 34 has a replacement author in addition to the continuing contributor. Chapters 24, 26, 28 through 33, 35 to 37 have continuing authors contributing for the fifth edition.In volume 1 Chapter 12 is a new chapter, and in volume 2 only Chapters 39 and 40 are new chapters which are addressed by code experts with chapter 39 being a futuristic chapter covering fusion energy devices and Chapter 40 being a chapter tracing the histori- cal background of code rules for nuclear vessels. Continuing chapters of the fourth edition are chapters cover- ing B31.9 Building Services and ASME Standards For Piping; B31T Standard For Toughness Requirements For Piping; B31.5: Refrigeration Piping and Heat Transfer Components; B31E Standard for Seismic Design and Current ASME Edition Retrofit of above Ground Piping Systems; B31J Standard for Test Method for Determining Stress I- Factors for Metallic Piping Compo- nents; B31.4 Standard for Pipeline Transportation Systems for Liquid Hydrocarbons and Other Liquids; B31.11 Standard for Slurry Transportation Piping; B31G: Manual for Determining the Remaining Strength of Corroded Pipelines and B31Q: Qualification of Pipeline Operators; and B31.12: Hydrogen Piping and Pipelines.

IntroductionThis fifth edition is in two volumes composed of 11 Parts, with Parts 1–5 in Volume 1, Parts 6–11 in Volume 2. Common to both volumes is the front matter, including the Organization of the Code. Organization and Operation of the ASME Boiler and Pressure Ves- sel (B&PV) Committee has been initially authored by Martin D. Bernstein for the first edition, appropriately updated in the second and third editions by Guido G. Karcher capturing the dramatic changes in the ASME B&PV organization. The fourth edition was updated by Joel G. Feldstein and Thomas P. Pastor. The current fifth edition is updated by Thomas P. Pastor, Ralph Hill III, and Richard (Rick) Swayne who hold senior leadership positions in the Boiler and Pressure Vessel Code Committees.An index is provided at the end of each volume as a quick reference to topics occurring in different Code Sections of that volume. In addition to indexing several topics covered in this publication, it is also meant to assist in reviewing the overlaps of the ASME Boilers & Pressure Vessel Code Sections/Subsections/Paragraphs occurring in the particular volume. In each chapter, all discussions generally pertain to the latest 2015 Code Edition unless noted otherwise by the chapter author(s).The fourth edition was published in 2012 in two volumes and had a total of 147 contributors for this publication, since the initial first edition. The third edition published in 2009 in three volumes was split into three separate books - the first was the fourth edition of the “Companion Guide to the ASME Boiler & Pressure Vessel Code” published in 2012 and the other two books were “Continuing and Changing Priorities of ASME Boiler & Pressure Vessel Codes and Standards” published in 2014; and “Global Applications of The ASME Boiler and Pressure Vessel Code” published in 2016. Unique for this edition with two volumes which addresses Code Sections I through XII, in addition to several ASME B31 Piping Codes is the inclusion of two additional chapters addressed by ASME Code experts who cover “Section III Div 4: Fusion Energy Devices” and “History, Philosophy, & Background of Section Ill, & Development of ASME Code Rules for Nuclear Vessels”.Each of the 51 contributors covering 40 chapters of the cur- rent fifth edition captured ‘up-to-date’ Boiler and Pressure Vessel Codes and Standards, making this publication once again a com- prehensive “Companion Guide Book”. The ASME Code is generally accepted in the United States (and in many foreign countries) as recognized minimum safety standard for the construction of pressure vessels and piping. Toward that end, these two volumes can be considered “a primer.” Although this primer is authored by several Code Committee members who are considered experts in their respective fields, the comments and interpretations of the rules contained in this publication are strictly the opinions of the individual authors; they are not to be considered official ASME Code Committee positions.Volume 1 has five Parts, each addressing a unique aspect of the Code. Part 1 covers Power Boilers (Code Sections I and VII); Part 2 covers Materials and Specifications (Code Section II). Scope of Part 2 has been considerably enlarged to address the “sub-topics” of “material specifications” which are the essence of the B&PV Codes and Standards. Basis for Acceptance of B&PV Codes for “International Material Specifications” are also addressed. Considering the importance of current and future nonmetallic construction codes and standards, coverage of Section 3.6 of Chapter 3 of fourth edition has been included in the discussions of Chapter 12 of this fifth edition. Part 3 provides an in-depth commentary on Rules for Construction of Nuclear Power Plant Components (Code Section III, Division 1). Previously, “Pumps” and “Valves” were addressed in a single chapter in the third edition. This edition continues the coverage of fourth edition Chapter 13 dealing with nuclear pumps and Chapter 14 addressing nuclear valves. In addition, changes in this fifth edition are in Chapters 12 and 17. Chapter 12 discussed Subsection NH in previous editions. However, because Subsection NH has been incorporated into Section III, Division 5, the discussion previously presented in Chapter 12 has been incorporated in Chapter 17. On the other hand Chapter 12, in this edition is based on a Report on Committee on Nonmetallic Pressure Piping Systems detailing NM-1 Thermoplastic Pressure Piping Systems; NM-2 FRP Pressure Piping Systems and NM-3 Nonmetallic Materials which includes specifications and material properties similar to BPV Code Section II. As in the previous editions, Section III Division 2 continues to be included in Part 3, addressed by several additional contributors with expertise in their respective areas. Section III Divisions 3 and 5 are included in Part 3, with Division 5 addressing the “Generation IV Nuclear Reactors”, which is an add-on-aspect of this edition. Part 4 covers Sections IV and VI of B&PV Code. Part 5 covering Nondestructive Examination (NDE), Code Section V of B&PV Code is now included in Volume 1. Volume 2 covers Parts 6–11, with Part 6 covering Section VIII– Rules for Construction of Pressure Vessels. In Part 6, experts dealing with Divisions 1, 2, and 3 provide in-depth criteria and commentary of Code Section VIII with the latest of the code stipulations. In addition there is a chapter by an expert of the B&PV Code who discusses safety and litigation issues. Part 7 addresses welding and brazing qualifications of Code Section IX by the contributor with expertise at the helm of Code Committee deliberations. Part 8 covering Code Section X pertains to fiber-reinforced plas- tic pressure vessels has been considerably revised by the current contributor for this edition. Part 9 providing in-depth discussions of Code Section XI in Chapters 27 through 34 is updated by authors associated with the specific subgroups and subcommittees dealing with the topics addressed in the previous editions. A chapter from the third volume of the third edition dealing with Applications of Elastic-Plastic Fracture Mechanics is included in this volume. Part 10 covering Code Section XII dealing with Transport Tank Code which was in the third volume of the third edition is now included in this part. Part 11 updates the coverage of ASME B31 Codes and Stand- ards in Chapters 35 through 38. Chapter 35 has Code for B31.1 Power Piping and Chapter 36 updates B31.3 Process Piping and B31.5, B31E, B31J and B31T. Chapter 37 updates the coverage of fourth edition topics B31, B31.8, B31.11 and B31Q; and Chapter 38 updates B31.12. Two additional chapters are covered in a new Part 12 of this fifth edition which provides in two separate and consecutive chapters ‘futuristic’ and ‘historical’ aspects of ASME B&PV Codes and Standards. Chapter 39 provides the futuristic aspect – a new “Section III Div 4: Fusion Energy Devices” and in chapter 40 the “history and philosophy of Section III” are discussed.

IntroductionThis fifth edition is in two volumes composed of 11 Parts, with Parts 1–5 in Volume 1, Parts 6–11 in Volume 2. Common to both volumes is the front matter, including the Organization of the Code. Organization and Operation of the ASME Boiler and Pressure Ves- sel (B&PV) Committee has been initially authored by Martin D.

Toward that end, these two volumes can be considered “a primer.” Although this primer is authored by several Code Committee members who are considered experts in their respective fields, the comments and interpretations of the rules contained in this publication are strictly the opinions of the individual authors; they are not to be considered official ASME Code Committee positions.Volume 1 has five Parts, each addressing a unique aspect of the Code. Part 1 covers Power Boilers (Code Sections I and VII); Part 2 covers Materials and Specifications (Code Section II). Scope of Part 2 has been considerably enlarged to address the “sub-topics” of “material specifications” which are the essence of the B&PV Codes and Standards. Basis for Acceptance of B&PV Codes for “International Material Specifications” are also addressed. Considering the importance of current and future nonmetallic construction codes and standards, coverage of Section 3.6 of Chapter 3 of fourth edition has been included in the discussions of Chapter 12 of this fifth edition. Part 3 provides an in-depth commentary on Rules for Construction of Nuclear Power Plant Components (Code Section III, Division 1). Previously, “Pumps” and “Valves” were addressed in a single chapter in the third edition. This edition continues the coverage of fourth edition Chapter 13 dealing with nuclear pumps and Chapter 14 addressing nuclear valves. In addition, changes in this fifth edition are in Chapters 12 and 17. Chapter 12 discussed Subsection NH in previous editions. However, because Subsection NH has been incorporated into Section III, Division 5, the discussion previously presented in Chapter 12 has been incorporated in Chapter 17. On the other hand Chapter 12, in this edition is based on a Report on Committee on Nonmetallic Pressure Piping Systems detailing NM-1 Thermoplastic Pressure Piping Systems; NM-2 FRP Pressure Piping Systems and NM-3 Nonmetallic Materials which includes specifications and material properties similar to BPV Code Section II. As in the previous editions, Section III Division 2 continues to be included in Part 3, addressed by several additional contributors with expertise in their respective areas. Section III Divisions 3 and 5 are included in Part 3, with Division 5 addressing the “Generation IV Nuclear Reactors”, which is an add-on-aspect of this edition. Part 4 covers Sections IV and VI of B&PV Code. Part 5 covering Nondestructive Examination (NDE), Code Section V of B&PV Code is now included in Volume 1. Volume 2 covers Parts 6–11, with Part 6 covering Section VIII– Rules for Construction of Pressure Vessels. In Part 6, experts dealing with Divisions 1, 2, and 3 provide in-depth criteria and commentary of Code Section VIII with the latest of the code stipulations. In addition there is a chapter by an expert of the B&PV Code who discusses safety and litigation issues. Part 7 addresses welding and brazing qualifications of Code Section IX by the contributor with expertise at the helm of Code Committee deliberations. Part 8 covering Code Section X pertains to fiber-reinforced plas- tic pressure vessels has been considerably revised by the current contributor for this edition. Part 9 providing in-depth discussions of Code Section XI in Chapters 27 through 34 is updated by authors associated with the specific subgroups and subcommittees dealing with the topics addressed in the previous editions. A chapter from the third volume of the third edition dealing with Applications of Elastic-Plastic Fracture Mechanics is included in this volume. Part 10 covering Code Section XII dealing with Transport Tank Code which was in the third volume of the third edition is now included in this part. Part 11 updates the coverage of ASME B31 Codes and Stand- ards in Chapters 35 through 38. Chapter 35 has Code for B31.1 Power Piping and Chapter 36 updates B31.3 Process Piping and B31.5, B31E, B31J and B31T. Chapter 37 updates the coverage of fourth edition topics B31, B31.8, B31.11 and B31Q; and Chapter 38 updates B31.12. Two additional chapters are covered in a new Part 12 of this fifth edition which provides in two separate and consecutive chapters ‘futuristic’ and ‘historical’ aspects of ASME B&PV Codes and Standards. Chapter 39 provides the futuristic aspect – a new “Section III Div 4: Fusion Energy Devices” and in chapter 40 the “history and philosophy of Section III” are discussed.
