I am looking people (someone, anyone) who have experience with high temperature pipe-in-a-pipe systems. I was told of a facility that uses a such a system for hot air at 1350+ F and 650 psig. The inside pipe (12") is vented to the outside pipe (~20") such that it is not pressure retaining; it acts as a conduit for the flow only. The outer pipe is insulated from the inner pipe and is pressurized to 650 psig; However, since no flow exists between the inside and outside pipe, there is very little heat transfer such that normal piping materials can be used The inner vented pipe has expansion joints to allow thermal growth independent of the outside pipe. Is anyone aware of a manufacturer of such a system?
