ASME BPE (2009) section SD-4.7.1 (e) states 

 

(e) Vessels that are to handle above 176°F (80°C) [e.g.,SIP, hot water-for-injection (WFI), hot U.S. Pharmacopeia (USP) waters, and hot CIP solutions] should be designed for full vacuum service.
 
 
 
I have an API 650 tank that needs cleaning in place which sprays 95degC water and immediately rinses with 20degC water. I have no way to calculate the immediate shrinkage effect (inbreathing effect) with this kind of scenario. The tank is open vent with 2" nozzle (HOLD).
 
Contrary to ASME BPE code I mentioned above, API 650 tank cannot be designed FV. 
 
Does anyone designed CIP of API 650 tank here? Is this possible? Any solutions would be appreciated.

Tank holds SOY SAUCE during process at ambient condition.
