Sun, 05 October 2003 12:06 they work in different ways, but overall the HPC should work better. (HPC 'extreme' coating that is, and coated inside and out) my reasoning is that the HPC coating: a) stops heat getting from the exhaust gas to the metal, by decreased heat absorbtion and conduction, b) decreases heat transfer from the metal to the outside air. thermal wrap is basically trying to form a heat barrier on an already hot pipe. the HPC will last longer and keep things cooler.. for a reference, thermal barrier coatings (TBC's) on jet turbine blades may only be 0.05-0.1mm thick, but they reduce the metal surface temp by a few hundred degrees. so just becuase the HPC seems thin, and the thermal wrap is thicker, doesn't mean the wrap is better... oh and another thing, i tested some 'High Energy' thermal wrap in one of my 1000C furnace to see what temp it is good for.... oops... it sort of puddled in the middle (wasted a $1000 furnace tube ) i think that the wrap is only good for about 400-500C max, after that it will start to melt together. you can even get it to start softening and melting with a lighter flame!!!! if your dump pipe gets red hot, then thermal wrap will not last.
