The conservative material prescription for heat tracing is carbon steel. But however you have take into account where the plant is installed, like cold countries where the winter temp. drops quit low. This is independent of the design temp. of the service. So refer the contract for the Min. metal design temp. for piping, because it does vary between equipments design and piping design.
With regards,

Dear All,
The Fluid for Industrial Heating Water is a mixture of Glycol 56 % and Water 44 %,
PMC has suggested use of Low Temperature Carbon Steel Materials,
Please Throw some light on Proper Piping Material for the said Fluid, The Design Temperature is 130 Deg C Max and Pressure is 16 Kg/Cm2.
I have used previously SS 316, For MEG Service, Services in a petrochemical plant.
