Need Help on Drafting Abbreviation
(OP)
I have an old drawing from the 50's of a vacuum tower that is carbon steel with a alloy liner on the inside of the shell. I know the liner is either 410S or 317 S.S. The liner is called out on the drawing as a 5/64" thk U.M. liner.
At this point I am not sure if the liner is Cladding, Weld Overlay or a sheet liner because I can only find a very few drawings for this item. What I would like to find out, if anyone knows, is what the U.M. stands for. Is anyone familiar with this abbreviation?

Don't remember what it stands for, just that it was welding.
Stands to reason with a vacuumn tower.

We are going to be installing several new nozzles in this column and I am just trying to prepare in advance of the TAR. I would like to avoid any surprises and was not familiar with this abbreviation. Thanks to those who responded.

5/64" thk. liner? Seems too thin for cladding or weld overlay. It's probably some kind of paintlike coating.
