Conduit for circulation of fluid under pressure

A conduit for the circulation of fluid, said conduit having a transversal section in excess of 2 square meters, and comprising a metallic pipe made up of a plurality of prefabricated elements positioned in sequence and welded to one another, said pipe having a longitudinal axis and attached to a rigid supporting body,

• (a) said pipe forming a sealed tubular enclosure, and each of said elements comprising a lower part having a U-shaped profile with two sides and an upper part;
• (b) said supporting body comprising a horizontal base with a lower plane face bearing on the laying surface and two lateral wings extending vertically along the sides of the lower part of the tubular enclosure;
• (c) wherein the supporting body comprises, on either side of the tubular enclosure, a substantially continuous portion completely surrounding said lower part of said tubular enclosure, and having, in cross-section, an L-shaped profile comprising a substantially vertical branch forming a lateral wing of the supporting body extending along the corresponding side of the lower part of the pipe and a substantially horizontal branch extending beneath said lower part of the pipe and forming at least a portion of the base of the supporting body resting on a support surface;
• and
• (d) wherein at least over a predetermined length, the supporting body is a unitary piece, and the horizontal branches of both L-shaped portions meet to form the base of the supporting body.
