ABSTRACT:
A conduit arrangement for heavy duty purposes in which a conduit section, such as a length of flexible hose, may be subjected in use to high stresses from pressures attaining several hundred atmospheres, wherein the arrangement provides protection against ruptures and significant leaks and comprises stop valve means at the inlet end of the conduit section, pressure drop type flow sensing means (e.g. an orifice plate or venturi restriction) at the outlet of said section, and pressure comparator means for comparing the pressure drop over the flow sensing means with that over the stop valve means and operative to effect a rapid closing operation of the stop valve means if the ratio of said pressure drops deviates by a certain amount from a predetermined value.
