Dead Leg Freezing Versus Thermosyphon
Dead Leg Freezing Versus Thermosyphon
(OP)
I have a 12" water pipe flowing at 50deg C with a long 2" vertical dead leg in the 12 o'clock position. Can i rely on the thermosyphon effect (hot water rising into dead leg due to high density) to justify not heat tracing the 2" stagnant line.
The line can be exposed to min ambient temps of -15 deg C.
Thanks.

If it is 2 FEET, then no, a 2" pipe won't conduct enough heat to prevent this and you need to trace heat this line.
