ABSTRACT:
A heat exchanger tube (2, 2a, 2b) is made using a hollow, impermeable, monolithic ceramic inner tube (4) and wrapping the inner tube with a circumferentially extending reinforcing material (12) impregnated with a slurry of ceramic particles, particle carrier medium and thermoset binder. The combination of the inner tube and the impregnated reinforcing material is first heated to solidify the thermoset binder. The combination is then sintered to drive off the particle carrier medium and themoset binder to create a two-layer heat exchanger tube including the inner tube and an outer tube (6).
