Table 10 shows estimated time to freezing calculated using these equations for the specific case of still water with t i 42F and t a 18F. In this study methodology from the refrigeration industry is applied to calculate the estimated time to freeze for liquids in pipes. Heat tracing is expensive but depending on your circumstances it might be your only option because you would have to prove that is will not get below 40 and that it will take.

Pipe offset calculator. Whilst insulation cannot totally prevent water freezing if correctly selected it should help delay ice formation until warmer conditions return. 34 pipe holds approx 5-12 cu in of water 02 and it takes 143 BTU per pound of water to freeze.

The calculator also ignores the thermal resistance and capacitance of the pipe wall. For a pipe use its length instead of height. They have a program called TraceCalc Pro2 that maybe can help.
