I didn't know that this was against any established protocol. My intent was to solicit feedback from other users who may not be members in the Structural Engineers forum. Thanks.
Thanks for taking the time to read this post. Does anyone out there have a suggested weld-procedure to weld a 317L nozzle into a 5Cr flush patch? I'm considering the option as a temporary replacement for a number of thermowells and vent connections on a 5Cr vacuum tower transfer line. I'd...
Metengr,
Thanks for your response! The reason I'm leaning towards the patches is because we've had several thru-wall failures in the HAZ of the nozzles in addition to local thinning of the nozzle. FYI, we're also installing a reinforced 20" manway into the line to facilitate fit-up and...

First, thanks for the info! FYI, we have a corrosion inhibitor (chem injection) to mitigate the issue with NAC on the straight-runs; but this type of corrosion most difficult to control in areas of two-phased flow, directional changes and more turbulent locations adjacent to welds (e.g ells and...
Gents,
I have a reduced crude vacuum transfer line (700F) subject to localized napthenic acid attack. Metallurgy on the line is 5CR (A335 GR P5). One of our options is to upgrade a number of small-bore connections (thermowells, vents, etc.) and L.R. ells to 317L. Could someone provide general...
