Abstract
A method for providing a fluid supply conduit configured to pass through a constrained environment, including providing a circular section tube of appropriate dimensions, die stamping the circular section tube so as to obtain an oblong section tube of oval section, providing a plurality of external stiffeners of hollowed out shape adapted to the external dimensions of the oblong section tube, assembling the external stiffeners around a portion of the section of the oblong section tube.
Claims6
A fluid supply conduit configured to pass through a constrained environment, comprising:
- at least one oblong section tube having a substantially oval section, and
- a plurality of external stiffeners of hollowed out shape with a U-shaped section adapted to encircle the oval section tube over a portion of its section, the plurality of external stiffeners being distributed in pairs over a length of said tube, such that two successive external stiffeners of each successive pair are positioned head to tail around the oblong section tube to form an alternating banding around said tube.
