Abstract

Claims18
A highly flexible and hydrolysis and burst resistant, coolant conduit comprising a plurality of layers of different polymers compatible with one another at the contact surfaces of the layers, the conduit being at least partially, including a plurality of ribs for connecting pairs of adjacent corrugations, wherein each corrugation is connected to a successive corrugation by at least one rib positioned in a first plane, said successive corrugation being connected to a next successive corrugation by at least one rib positioned in a second plane, said second plane being angularly offset from said first plane by a defined angle, wherein said ribs in the first plane and ribs in the second plane alternate in the longitudinal direction of the conduit between said pairs of corrugations, whereby said ribs between one adjacent pair of corrugations are angularly offset from said ribs between a next adjacent pair of corrugations, the external layer being made of a polymer selected from the group consisting of homopolyamides, copolyamides, blends thereof and mixtures thereof with one another and with other polymers.
