Dual Walled Titanium Tubing and Methods of Manufacturing the Tubing

摘要

Within examples, a method of manufacturing a double-walled titanium conduit is described. Example methods include stitch welding multiple concentric sheets to form a stitch layer, providing the stitch layer between an inner wall and an outer wall of the double-walled titanium conduit, circumferentially seam welding the inner wall and the outer wall to the stitch layer to create a welded assembly, die forming the welded assembly at temperature and pressure to form inner structures between the multiple concentric sheets according to stitch welding lines and to enable a diffusion bond process among the inner wall, the stitch layer, and the outer wall, and removing the double-walled titanium conduit from the die.

主权项

1. A double-walled titanium tube structure, comprising:
an inner wall and an outer wall with a plurality of stiffeners extending between the inner wall to the outer wall; and wherein the plurality of stiffeners are aligned both axially and radially, and the plurality of stiffeners are diffusion bonded to the inner wall and the outer wall.
