Abstract
A tube transition fitting includes a body having a scalloped end having a raised portion and a depressed portion connected by a continuously sloping transition portion. The fitting is formed having a first wall thickness and a second wall thickness. A tube seat is formed on a surface connected to the body, the surface being adjacent a transition from the first wall thickness to the second wall thickness. A tube transition assembly includes a header portion, the tube transition fitting, and a heat exchange tube, each being connected using one or more simplified and/or heat-optimized connections.
Claims25
A heat exchanger tube transition fitting, comprising:
- a body having a first end and a second end, the second end opposing the first end;
- a head adjacent the first end;
- a weld area adjacent the head, the weld area being configured such that the tube transition fitting may be welded to a header of the heat exchanger;
- a first wall thickness;
- and
- a second wall thickness.
A heat exchanger tube transition assembly, comprising:
- a heat exchange tube;
- a header portion;
- and
- a tube transition fitting, comprising:
- a body having a first end and a second end, the second end opposing the first end;
- a head adjacent the first end;
- a first wall thickness;
- and
- a second wall thickness;
- wherein the head of the tube transition fitting is inserted into the header portion.
A method for connecting, repairing, or replacing a heat exchange tube, comprising:
- providing the heat exchange tube;
- providing a header portion;
- providing a tube transition fitting, comprising:
- a first end and a second end opposite the first end;
- a body;
- a first wall thickness;
- and
- a second wall thickness;
- fitting the heat exchange tube with the first end of the tube transition fitting;
- and
- securing the second end of the tube transition fitting to the header portion.
