New Hose Breakaway Coupling Prevents Spillage —Literature Available A hose safety breakaway cou- pling designed to avert the dan- ger of broken hoses and reduce the risk of pollution, will be shown for the first time in the United States at the Offshore Technology Conference in Hous- ton, Texas, May 5-8, 1980. The hose safety breakaway coupling is a deliberately weak link that will part before the hose breaks. Although designed initially for tankers loading and unloading oil, the system is equally suitable for vessels carrying toxic chemicals or other liquids whose accidental spillage would be undesirable. It is available in 6"-24" sizes; larger sizes can be manufactured as needed. The upstream side of the cou- pling contains "petals," radially located one to another by steel balls and contained in an annular groove, pivoting so that they fit against the inside of the body when the two halves of the cou- pling are joined, ensuring a full through bore. When the coupling parts, the flowing product begins to force the petals closed. However, under The Gall Thomson hose safety break- away coupling is designed to avert hose breakage and reduce risk of pollution. each petal cantilever there is a hydraulic damper unit, from which hydraulic fluid can escape via a pre-set jet; this controls the rate of closure, to prevent spillage and line shock. The rate at which the petals close can be varied by altering the jet size or the viscosity of the hydraulic damper fluid. Recharging the cylinders after rejoining the coupling, using a new set of break bolts, allows it to be reinstalled with a minimum of downtime. The parting load is also variable to suit the design limitations of the hose string. The self-contained couplings op- erate automatically and need no outside power source or control gear.
