Hydrogen Piping and Pipelines

ASME B31.12, Hydrogen Piping and Pipelines was first published in 2008 to address gaps in existing piping codes with respect to needs for hydrogen infrastructure applications.  The standard includes consideration of the effect of hydrogen on material properties. It has been decided to incorporate relevant hydrogen service requirements into ASME B31.3 (piping) and ASME B31.8 […]

Evaluation of Piping Loads on Nozzles

Are load considerations different between vessel nozzles and pump nozzles?  In general, yes.  For vessels, nozzle loads are generally calculated to determine if reinforcement of the nozzle is required for it to safely accept the loads.  For a pump, design of the nozzle for the loads is not the consideration.  Rather, it is the net […]

Changes to f Factor in ASME B31.3 in the 2022 Edition

In the 2022 edition of ASME B31.3, the f factor was changed. There have been some mixed reactions in articles and social media; hopefully, this blog can put the matter in perspective. The f factor is used to reduce the allowable displacement stress range to prevent fatigue failure.  It is based on welded pipe fatigue […]

When Should the Rules for Severe Cyclic Conditions (Service) in ASME B31.3 Be Used?

This posting (November 2019) is an update to an October 2013 post which reflects changes to the ASME B31.3 Code relative to severe cyclic service that have occurred since the original post. There has been a fair amount of confusion as to when the rules for severe cyclic conditions in ASME B31.3 should be used, […]

Elastic Follow-up Can Result in Failures in Systems that Comply with Piping Code Rules

The analysis procedures in the Code essentially assume that the strain range in the system can be determined from an elastic analysis. That is, strains are proportional to elastically calculated stresses. The stress range is limited to less than two times the yield stress, in part to achieve this. However, in some systems, strain concentration […]
