Abstract

La présente invention concerne un pipeline, composé d'un tube interne (10,10',10'') attaché fixement à un tube externe (12,12'), dont la disposition permet, lorsque la température des tubes interne et externe est la même, que le tube interne (10,10',10'') soit dans un état de tension longitudinal et le tube externe (12,12') soit dans un état de compression longitudinale. La présente invention concerne aussi un procédé et un dispositif de façonnage dudit pipeline.
