ABSTRACT:
A heat transfer tube for the water-spray panel evaporator for the gasification of liquefied natural gases which includes a tube having a pair of planar members each projecting outwardly from its peripheral surface, radially with respect to its longitudinal axis and extending longitudinally along such axis, and an internal fin disposed within the tube and having at least three fin members each projecting radially with respect to the longitudinal axis to provide a helicoidal formation extending along and about the longitudinal axis, the helix of the helicoidal formation contacting the internal wall of the tube in a pressure-fitting relationship. These heat transfer tubes can be assembled to provide a panel evaporator. The method for fabricating such heat transfer tubes and assemblies is characterized in that the above pressure-fitting relationship is established by drawing the tube alone to reduce its internal diameter until the helix of the helicoid is abutted against the internal wall of the tube.
