How much temperature can a 1-meter-long stainless steel pipe lower?
Thread Content
Dear seniors: Does anyone know how much temperature can be reduced per meter by a 14*2 stainless steel pipe?
If it’s heat exchange between the inside and outside, the temperature difference needs to be known; if it’s simply heat conduction from end A to end B, I need guidance from experts

For example: if the fluid inside the pipe is at 35 °C and the temperature outside the pipe is also 35 °C, then after traveling 10,000 meters, the temperature will not decrease at all. Also, is heat preservation available? Steel pipe wall thickness? Wait, wait, wait. So when asking a question, make it clear; otherwise, who would want to waste time?
I’ve learned something: at room temperature, for a 1-meter-long stainless steel strip with dimensions of 14*2 and a wall thickness of 2 mm, if air at 300 degrees is introduced at end A, what temperature will be reached at end B?

For the rest, at least the flow rate and pressure need to be known……
LZ sees the problem so simply, haha.
Can I take this as you being sarcastic with me? It’s a challenge for newcomers; please don’t be so direct. For this situation, you can give examples; that’s exactly what I want to know. Or you can tell me which area it relates to so that I can look it up myself. Thank you!
It’s because I don’t know much that I want to learn about this area; thank you!
Parameters are still missing; I need to know the flow rates, flow directions, and temperatures of the fluids on the hot and cold sides. That’s more or less what counts.
