N630 Advanced 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 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).

Duration and Training Method
