Client's specifications say that u-bends of tubing in HEx need to be heat treated / solution annealed. I cannot figure out where does this requirement come from.
*TEMA RCB-2.33 Heat Treatment* says that: "...heat treatment may be performed by agreement..." but does not give any specifics.
API 660 says nothing about it.
I was not able to find any requirements in the Code in either SA-179 or SA-450 spec's.
Any help would be appreciated.
