  • Flexible hose with a visibly deformable structure upon an internal failure within the hose
    Patent number: 5518034
    Abstract: A flexible hose which makes possible the early visual detection of a malfunction, can have a structure which allows a localized deformation in specified zones. This structure can have a combination of at least one radial expansion zone, and at least one compensation zone, wherein a localized deformation can occur as soon as the leak pressure of the leaking fluid reaches a threshold value which is only a fraction of the operating pressure of the fluid being transported through the hose.
