Recently, the gas process component has large change in some harmful component specially h2s which reaches to 1000 ppm.
Now we want to replace the existing bundle for gas air cooler by new one.
The existing material for the old bundle is
Tubes sa- 214
Tube sheets, plug plates and end platez sa- 516 gr.70
We will change only the material for tubes.
There is two options.
Using Sa-179 HIC Material
Using duplex stainless steel.
P : 1174 psi
T : 275 °F
FLUID Natural gas
In your opinion , what are the best material for tubes suitable for these conditions and keep no change in tubesheet material.
