Dave Diehl,

Thank you for the response.

I just want to ask regarding temperature to be considered in the buried pipe.
We consider the solar temperature at 90degC and disregard the Max Design Temp. of 65degC, my question is, if it is feasible to consider 65degC for buried pipe while in the abovegroud is still 90degC considering the solar radiation?

Thank you in advance.

Sincerely,

marchie
