An operator’s perspective on ASME B31.3 post weld heat treatment exemptions


Via webinar 12:30-13:30.




ASME B31.3 2014 no longer requires PWHT (post weld heat treatment) on carbon manganese steels if you apply a decent level of preheat. Have operators' efforts over the past 30 years been wasted? This presentation will address the changes from an offshore oil and gas operator’s perspective, and the issues it raises with regards to existing process pipework and future projects.

The webinar will be presented by Shell's Kevin Millican, a member of EEMUA’s Materials Technology Committee (MTC). Kevin is also a contributor to numerous EEMUA working groups including EEMUA 143, 158, 234 and the upcoming EEMUA 233. 

The EEMUA Piping Systems Committee (PSC) plan to develop a new edition to the previously withdrawn EEMUA Publication 153: Supplement to ASME B31.3 to give the user additional guidelines on the considerations of post weld heat treatment (PWHT) to support the ASME code change. The MTC will also be contributing to the update. 

Who should attend:

Engineers with an interest in piping, materials and pressure systems.
