摘要
The pipes (1) are each made up of two co-axial tubes (10, 20) between which is placed a filling casing (15). The casing (15) is made of insulating material and/or ballasting material. The casing (15) is not placed at the junction sections (26, 32) of the internal tubes provided at each of the two opposite longitudinal ends of the pipe or the internal tube (10). The pipe (1) also has a coupling sleeve (3) which slides on the outside tubes.
