ABSTRACT:
For assembling together a bundle of parallel tubes (1) recourse is had to flexible and sealed pipes (2) inserted jointingly between the successive layers of these tubes, said pipes having sufficient elasticity for being successively flattened by evacuation of their inner volume, which allows positioning thereof in the bundle, then resuming their initial tubular shape by suppression of the vacuum, and said pipes are made from a partially crystalline plastic material, such as a polyamide 11, which allows them to be positioned in the bundle by simply pushing from their portion not engaged in the bundle.
