Abstract (en)

[origin: FR2789096A1] The invention relates to a liquid circulation duct comprising a pipe (1) that is fixed to a solid, rigid support (B) in order to form a base that rests on a standing surface (C). The pipe (A) is made of a thin resistant wall that forms a tight tubular enclosure. On each side of the longitudinal axis (O, O'), the solid, rigid support (B) is provided with a single-piece component (31, 31') having an L-shaped profiled cross-section comprising a substantially vertical branch (32) that extends along a corresponding side of the enclosure (A) and a substantially horizontal branch (33) that extends underneath the latter, forming at least one part of the base (3) of the solid support (B) that rests upon the ground.
