When you say run lengths, are you talking about tube life or are you talking about run lengths before you have to decoke? If you are talking about tube life, I don’t think 347 has be in long enough to determine tube life yet. If you are talking about run lengths between decokes, it will depend of how hard you run your heater. If you start to run higher tube skin temps, you will coke just about as fast but the higher skin temp won’t tend to damage the tube material as fast as 9 chrome would. I hope that this makes soom since.
