ASME B31.3 is a set of guidelines created by the American Society of Mechanical Engineers (ASME) that provides instructions for the design, construction, and maintenance of process piping systems. It is widely accepted and used by professionals in the industry to ensure that piping systems meet regulatory requirements and are safe and dependable.

ASME B31.3 covers a broad range of topics related to piping systems, including material selection, calculations for pipe wall thickness, design of supports and restraints, welding techniques, and inspection and testing requirements. It is frequently updated to reflect the latest industry developments and best practices.

What Is The Latest Edition Update of ASME B31.3?

The 2022 edition of the ASME B31.3 Process Piping Code has made several changes and additions to its definitions and requirements. Cited from ANSI, here are some of the latest updates of ASME B31.3:

  1. New definitions have been added for construction, designated lot, combination welded (COW) pipe, post weld hydrogen bakeout, and set pressure while existing definitions have been revised.
  2. Double-seated valves are now subject to specific requirements.
  3. Table 323.2.2A, which provides tabular values for minimum temperatures without impact testing for carbon steel materials, has been completely revised.
  4. Welding requirements have been updated to include prohibitions on peening, and clarification has been provided on post weld hydrogen bakeout performed at a temperature.
  5. Clarification has also been added for progressive sampling for examination.
  6. Part 5, “Flexibility and Support,” now addresses supports for piping lined with nonmetals.
  7. Table K341.3.2, which provides acceptance criteria for welds, has been completely revised.
  8. Appendix F, “Guidance and Precautionary Considerations,” now includes information on piping flexibility, examination requirements, and loads due to temperature gradients.

What Is ASME B31.3 Training Course Objective?

PetroSync’s ASME B313 training course, which lasts for five intensive days, aims to provide the attendees with a thorough understanding of the ASME B31.3 Process Piping Code and its practical application for all aspects of piping, from design to testing and certification. The training course will offer detailed insights into the code requirements for designing piping components, branch connections, selecting flanges and fittings, considering flexibility, materials requirements, fabrication, welding, non-destructive examination, and pressure testing. The training course will cover piping systems commonly used in industries such as petroleum, refineries, and petrochemical plants. It will emphasize the need to understand both the “stated” and “implied” requirements of the code, including its content and intent.
