Abstract
A ceramic heat exchanger tube (1) includes a hollow ceramic outer tube (2) with a corrugated ceramic fiber inner member (8) housed within and secured to the outer tube defining one or more fluid passageways (14) therebetween. The corrugated inner member helps to keep the outer tube from failing catastrophically by momentarily slowing down the initial outwardly expanding movement of the pieces of the failed outer tube. This keeps the pieces of the failed outer tube from being blown outwardly in a shrapnel-like manner to prevent damage to adjoining tubes.
