Advanced ASME B31.3 Process Piping Code

Course Code: N630
Instructors:  Don Frikken
Course Outline:  Download
Format and Duration
2 days


This two-day course will cover advanced topics related to the ASME B31.3 Process Piping Code. The sessions emphasize the piping flexibility analysis process, including practice application of simplified methods and illustration of computer analysis methods. This course also covers requirements for nonmetallic, Category M fluid service and high pressure piping, as well as in-service inspection to API 570 and a comparison to ASME B31.1 Power Piping requirements. Participants are requested to bring a calculator to the course, and are encouraged to bring a copy of the code (not included in course fees).


Excellent course. Lots of relevant information, good forum to ask questions, and insight on future ASME B31.3 code updates.

Duration and Training Method

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

Course Overview

Participants will learn to

1. Develop and understanding of how to perform a piping flexibility analysis.
2. Create acceptable arrangements for piping systems with expansion joints.
3. Develop an understanding of special considerations for nonmetallic, lethal service, high pressure, high purity and underground piping.
4. Formulate inspection plans for piping that has been placed in service.
