Effect of steel pipe material on results in HTRI calculations
Thread Content
I accidentally chose the wrong material for the steel pipe – I selected 316 when I should have used carbon steel. It turned out that carbon steel provides a better heat exchange performance. What is the reason for this? I would be extremely grateful if experts could give me some advice
Personal opinion: At 100°C, the thermal conductivity of austenitic stainless steel is approximately 1/4 that of carbon steel, and that’s it.
Agree with the opinion above； Stainless steel is chosen for the material mainly because its corrosion resistance is better than that of carbon steel and alloy steel ； There is little difference in terms of pressure resistance, but carbon steel still performs significantly better in terms of heat conduction.
