The rules in Chapter X of ASME B31.3 are used when the owner designates a piping system to be in High-Purity Fluid Service. The owner is guided in the classification for the piping system by the definition of High-Purity Fluid Service in Chapter I of ASME B31.3. This definition is the Code rule relative to classification. A guide to the application of these rules is provided in ASME B31.3, Appendix M, which contains a flow chart to assist the owner in classifying fluid services.

Chapter IX of ASME B31.3 only applies when the owner specifies its use. It applies to piping in High-Pressure Fluid Service. Note that the definition of High-Pressure Fluid Service simply requires that the owner specify use of Chapter IX. Some guidance is provided in FK300, which states “Although High Pressure Fluid Service is often considered to be service exceeding that allowed by the ASME B16.5, Class 2500 pressure-temperature rating for a particular material group, there are no pressure limitations for the application of these rules.” This is not a requirement, and the base Code may be satisfactorily used at pressures higher than ASME B16.5, Class 2500. However, the base Code rules become increasingly conservative and, in fact, impossible to use as the pressure approaches the allowable stress (including quality factors). See Section 17.3 for a discussion of pressure design of straight pipe. By the same token, Chapter IX may be used at lower pressures; it has been used with high-strength steels with pressures as low as 28,000 kPa (5,000 psi).

It is an ASME B31.3 requirement that piping systems be designed such that the reactions are not detrimental to the equipment to which they are connected. This equipment can be machinery, pressure vessels, tankage, or air fin heat exchangers, as well as a myriad of other possibilities. The Designer needs to be aware of the applicable load limits. Some are described herein as examples; however, this is not a complete list. The remainder of this chapter does not provide specific Code requirements; it provides general information on load limits for equipment.

The requirements for materials are covered in Chapter III of ASME B31.3. Selection of the appropriate material for a given service is not covered by the Code. As stated in para. 323.5, “Selection of materials to resist deterioration in service is not within the scope of this Code.” Practical considerations make it impossible for the Code to provide guidance relevant to the essentially unlimited process applications covered by the Code. Some precautionary considerations are included in Appendix F based on specific experience or interests of Code Committee members, but this is a very limited list of considerations.

This book is based on the 2020 Edition of ASME B31.3, Process Piping [Code]. Because changes, some very significant, are made to the Code every edition, the reader should refer to the Code for any specific requirements. This book should be considered as providing background information and not specific current Code rules. The equations in this book are numbered sequentially in each chapter. When equations from ASME B31.3 are reproduced herein the latter equation numbers are given as well.

The allowable stress for thermal expansion and other deformation-induced stresses is substantially higher than for sustained loads. This is due to the difference between load-controlled conditions, such as weight and pressure, and deformation-controlled conditions, such as thermal expansion or end displacements (e.g., due to thermal expansion of attached equipment).

Requirements for supports and other devices to restrain the piping are provided in Chapter II of ASME B31.3, specifically in Section 321, Piping Support. ASME B31.3 provides general requirements for piping supports as well as descriptions of conditions for which they must be designed. The support elements (e.g., springs, hanger rods, etc.) are within the scope of ASME B31.3, but the support structures to which they are attached are not. The supports must achieve the objectives in the design of the piping for sustained and occasional loads as well as thermal displacement.
