ABSTRACT:
A structure having at least two joined contiguous parts, of which at least one is straight and of uniform girth throughout its length, is jacketed with a given fluorocarbon resin by first cross feed extruding a jacket of said resin onto said one part, next providing a joint between said one part and another part, and thereafter coating at least said joint, any exposed surfaces of said one part present between said joint and the adjacent end of said jacket, and a narrow circumferential band at said adjacent end of said jacket with said given resin by spraying in dry powder form, and then applying heat to fuse said sprayed on resin. A heat exchanger is described where the exchanger tubes constitute the straight parts and the manifolds to which they are brazed the other parts.
