@chicopee - Thanks. protocol would be followed
@MJCronin - I have attached 3D model of some of the vessels. I think these kind of welding won't call for PWHT. https://res.cloudinary.com/engineering-com/image/upload/v1458461257/tips/Light_Naphtha_qhbdvc.pdf

@metengr - Thanks..However my client is looking for references to build up case to management. Appreciate if you have any.
@chicopee - Thanks. As per my R-stamp inspectors, it would be called as alteration since its addition of Reinforcement Pads (and not any repair).
Thanks @nickelkid - the pads would be put non-PWHTed petals. won't be near to nozzles
Thanks @metengr - design review has been performed by doing FEA. On query to second, do you recommend to engage same organization who did the U-Stamp? Note that the storage spheres are 30 years old. However...
I am struggling on an unique situation.
There are spheres which are U stamped almost 30 years old, on which fillet welding needs to be performed to put reinforcement pads to take out some pipe supports later. My question is, has it been done anywhere in the world? I know as per ASME, it is...
