Nozzles Fabrication
Nozzles Fabrication
(OP)
An attachment was mark up of the final fabrication drawings for the Froth Deaerator showing that two of the nozzles were fabricated without meeting the dimensions. 2" short. I am being asked to see if piping can accommodate this discrep, but I have been advised to check to see what the norm is for accepting errors like this. I guess I am asking that if you were inspecting this, and came across this issue, what action would you take? Should we ask for vendor to fix it? Should we adjust piping to accommodate?

In short, a lot of things you know but we don't.

I've seen solid plate flanges used as a spacer in between flange, and can't think what that's called, but it might be an option.

A common course of action would be to write a nonconformance on the vessel, give the vendor a padded rework cost for the pipe, and let them decide if they're going to come out and repair/replace the nozzle, or just eat your backcharge on the pipe rework. In my experience, the latter wins out 95% of the time.
