Abstract

Each corrugation (9,10) of the tube (1) along the first axis (2), has a different height to that of the same corrugation along the second axis (3), e.g. the first is smaller than the second. The two axes are at 90 degrees to each other. The corrugations end in an oval shaped floor (11), when viewed in section. The corrugated tube is enclosed on the outside by a hose (14) with metallic loops, which ends in the stiff, tube type, head sections (7). ADVANTAGE - Improved flexibility in plane, in which deformations occur, it is robust and has a long-life.
