Patent Images
1. A method of forming a jacketed steam distribution tube assembly, the method comprising:
- simultaneously extruding;
an inner tube;
an outer tube; and
a plurality of connecting members for connecting the inner tube to the outer tube, thereby forming a jacketed steam distribution tube assembly;
forming a plurality of orifices radially outwardly through one of the connecting members between an inner surface of the inner tube and an outer surface of the outer tube; and
disposing condensate flow barrier tubes in the orifices, the condensate flow barrier tubes extending from the outer tube to a point inward of an inner surface of the inner tube.

10. A method of forming a jacketed steam distribution tube assembly, the method comprising:
-
forming an outer tube; forming an inner tube; forming a first connecting member extending radially outward of the inner tube and connecting the inner tube to the outer tube; forming a second connecting member extending radially outward of the inner tube and connecting the inner tube to the outer tube; forming a plurality of steam orifices in the first connecting member, the steam orifices extending between an inner surface of the inner tube and an outer surface of the outer tube, thereby forming a jacketed steam distribution tube assembly; and disposing condensate flow barrier tubes in the orifices, the condensate flow barrier tubes extending from the outer tube to a point inward of an inner surface of the inner tube. - View Dependent Claims (11, 12, 13, 14)
