Dear all,

Kindly give your suggestions of my below query,

1. How to model the underground thermal Pre-insulated piping ?, while burring the underground all densities is going to zero since the underground piping is fully restrained.

2. For the thermal insulation, What the ambient temperature shall i give?, whether i can take soil temperature or room temperature 21 deg c, because the insulated piping is not direct contact with soil.

3. The pre-insulation is designed with Standard EN-253 and the Design fluid temperature is 93 deg C. Pressure 1088 PSI.

Same topic i already checked with this forum but that is not relevant to me.

Thanks in advance...
