For High Temperature Operation, All Internals' Reinf. Pads have Vent Hole as mandatory.
If you don't make Vent Hole, Reinf. Pad Inside will be sealed perfectly.
During Operation,High Temperature will expand Air inside Reinf. Pad due to Heat.
Finally, The Expanded Air will break Welding between...
SEE ASME SEC. VIII APP.2 AND UG-34.
OR CLIENT ACCEPTS OTHER CODE OR STANDARD, YOU CAN USE 'JIS CODE' ( <--- JAPANESE CODE.)
IN ASME, MIN. FLANGE RATING IS 150 PSIG ( 10.5 KG/CM2G).
BUT, JIS CODE PROVIDES FLANGE RATING BY 5 KG/CM2G.

Normally, Water Cooling need smaller heat transfer area than Air Cooling.
The Heat Transfer Coefficient of Air is smaller than that of Water.

Is there NO Groove for Passpartition Plate(Divider Plate) on Tubesheet?
Passpartition nornally to be inserted to groove on tubesheet. The deep of groove is 5mm from surface of tubesheet.

Applicable Materials of ASME are listed in ASME Code.
For example, See 'UCS-5' and 'Table UCS-23' for Carbon & Low Alloy Carbon steels in ASME SEC.VIII Div.1.
Dear MJCronin,
For Continuous Blowdown under Steady State, it's very small. I have experienced already.
But, for Intermittent Case (Non Continuous Blowdown)under Non Steady State, we should take account carefully.
This is only my simple opinion.
Moon.
Right! And, I fully understand!
For Condensate Receiver under steady state condition, I will consider The worst condition with considering many cases of Operating Conditions. And, I confirmed that The condensate receiver is Buffer Tank.
For Intermittent Receiver under Non-Steady state...
Thank you for your confirmation.
As per your request, I try to inform you more.
Condensate Tank under Steady State Condition :
The Condensate Receiver Tank is to take condensates from other process equipments.
After taking Condensates, These condensates move to next process such as Boiler etc...
I need Engineering Practice for Design of Receiver Tank!
The Following is example as Design Condition.
- Inlet Flowrate of Liquid(Condensate of Steam) : Q [kg/hr] with Density d[kg/m3]
With above flowrate, how to decide Tank Size?
Above case in under Steady Sate Condition.
But, How about NON...
