N619 Introduction to ASME B31.3 Process Piping Code

Course Facts

Course Code:
2 days
1.6 Continuing Education Units
16 Professional Development Hours
Certificate Issued Upon Completion


This two-day course will introduce participants to the ASME B31.3 Process Piping Code. The Code provides requirements for the design, fabrication, examination and testing of metallic piping systems designed for the wide variety of fluid services used in the process industries. Selection of materials, pipe, valves and fittings will be discussed. Participants are encouraged to bring a copy of the code (not included in course fees) to the session.

Each session is conducted in a lecture/discussion/problem solving format designed to provide intensive instruction and guidance on understanding Code requirements. The instructor will be available following each day’s session to provide participants with further opportunity for discussion and consideration of specific problems.

Duration and Training Method

Two classroom days providing 1.6 CEU (Continuing Education Credits) or 16 PDH (Professional Development Hours)

Participants will learn to:

1. Develop an understanding of when the rules of ASME B31.3 should be applied.
2. Choose ASME B31.3 fluid service designations for specific applications.
3. Develop an understanding of the advantages and limitations of various types of piping components.
4. Recognize when to seek help to select materials of construction.
5. Select wall thicknesses and component ratings based on design pressure and design temperature.
6. Define fabrication and installation requirements for piping systems.
7. Select examination and testing methods for piping systems.
