Thank you very much for your valuable information. Still some doubts
are there as given below.
As per AWS D10.10( Clause2.3.1)temperature variation up to 83deg is
acceptable and AWS D10.10 itself says that there is no way to
eliminate temperature variation though out the wall thickness(Clause
2.3).
Actually in our site we have materials with various thicknesses and
some up to 139mm and now question is.. what will be the temperature
variation for 139mm thickness(On jobs its not possible to measure
inside temperature).
Have any equation or formula to find out the temperature variation
throughout the thickness?
Have any role of Thermal conductivity of P91 in this case?
Is it possible a uniform temperature at OD and ID regardless of
thickness?
Awaits for your reply
Thanks and regards
