Molten metal is sprayed onto the outer shell 32 of a cooling tube bundle 10, and the ends of tubes 18, 20 are covered with predetermined thicknesses of the metal 52, 54. Circumferentially extending manifold channels 60, 64 that intersect each of the tube ends 18, 20 are then machined into the predetermined thicknesses of metal, and mating assemblies 74, 76 are attached to enclose the manifold channels 60, 64. <IMAGE> |
