ABSTRACT:
A heat exchange system having a first tube system of tubes which are interconnected to conduct a first fluid and a second tube system comprising tubes surrounding the tubes of the first system to conduct a second fluid in heat exchange relationship with the first fluid, the preferred embodiment of the tubes of the first system being double walled and shaped to provide a passage for the escape of any fluid leaking from an opening occurring in either the inner or outer wall of the tubes of the first system. In the preferred embodiment, the double walled tubes are concentric tubes spaced radially to permit formation of a spiral groove on one tube, preferably the outermost, which provides a spiral path between said tubes which is open to atmosphere at the ends. Detachable return elbows interconnect adjacent ends of the innermost tubes to effect a continuous path for the fluid therein and the elbows at one end are removable to facilitate cleaning said tubes.
