ASME B31.3 Course Objectives
Understand the basic ASME B31.3 code design requirements and to provide an overview of the Canadian regulatory regime as it applies to pressure piping systems; including an overview of the relationship between Provincial regulations, CSA B51, and ASME B31.3. We offer ASME B31.3 course in Calgary, AB and surrounding cities.
Upon completion, attendees will be able to determine when ASME B31.3 applies, and they will be able to complete basic code design calculations. In addition, attendees will gain a general understanding of the standards applicable to piping components commonly used in ASME B31.3 piping systems and the implications and/or limitations that these components may have in their piping designs.
There will be a brief overview of materials properties and attendees will gain an understanding of how materials properties are considered in code design; materials are more fully discussed in the Little P.Eng. ASME B31.3 Materials, Fabrication, and Inspection Course. An overview of pertinent construction requirements (e.g., examination requirements, pressure testing), will also be provided although construction requirements are not covered in detail.
Specifically, the ASME B31.3 course will attempt to highlight areas where code requirements may not fully meet local Canadian regulatory requirements. Throughout the course, there will be reference to applicable Code interpretations, and local regulatory bulletins, notices or advisories.
This is an introductory level design course and the discussion includes an overview of piping flexibility (i.e., stress) analysis requirements but it is not intended to provide detailed instruction on flexibility analysis requirements.
