A line system is intended for a system for pumping fluid products, such as gasoline, diesel fuel and chemicals, the pumping system comprising a pump (12) which makes it possible to pump such products from a storage tank (10) for supplying them, via the main pipe (30) of the pipe system, to a product distributor (18). The pipe system comprises a secondary containment system for the main pipe between the tank and the distributor, the latter system comprising sections of telescopic tube (32a, 32b) of different diameters. Telescopic piping is installed around the main pipe (30) and the tube sections are, before the final installation, movable between intermediate and final positions to allow the assembly to be completed, to test and to check the main pipe before the completion of the final assembly of the secondary containment system. A section of the telescopic tubing consists of a flexible corrugated tube (42) which can be bent. Compression seals and annular flanges (42a, 42b) are used to connect the components together. |
