<p>PURPOSE:To provide a hose with a structure with which, leakage of transported fluid is accurately detected with no fear of leakage to outside, with a simple structure. CONSTITUTION:The horse with a transported material leakage detecting structure, or a fluid transportation hose, wherein the outermost layer is formed along the outer periphery of a fluid transportation hose main body with buoyance materials 61 and 62 in between, with a secondary reinforcement layer 7 that splits the buoyance materials 61 and 62 into inner and outer ones provided, and with the secondary reinforcement layer 7 being a cross card having an angle larger than 54 deg.44' against the longitudinal direction of a horse. Therefore, molding of the secondary reinforcement layer 7 is identical with that of ordinal reinforcement layer, since its purpose is just to change angle, so, continuous molding is available, and reduction in molding processes is realized. Further, with changes in hose's diameter, length and changes in waterline, etc., chances to-be-detected rise. In addition, since no mechanical or electrical detection mechanism is provided at the end of the hose, reliability an long-term use significantly improves.</p> |
