Changes to ASME B31.3, "Process Piping"

By Vince Carucci

The 2014 edition of ASME B31.3 is a revision of the 2012 edition, was officially issued February 27, 2015, and became effective six months after that date. As with previous editions, it includes several pages at the beginning that highlight where changes were made, and these are further identified by a margin note (14) in the body of the code placed next to the affected area.

This article highlights several, but not all, of the technical changes. Please refer to ASME B31.3 for complete details.
