<p>A frangible pipe coupling includes a pair of pipes with a plurality of frangible connectors extending between the pipes and normally holding the pipes in sealed engagement with one another. An annular member surrounds one of the pipes and is slidably mounted thereon for longitudinal sliding movement relative thereto, the annular member cooperating with the pipe to form a chamber therebetween. Fluid is supplied under pressure into the chamber to effect longitudinal sliding movement of the annular member relative to the pipe, the annular member being connected to the frangible connectors to cause the relative movement between the annular member and the pipe to break the frangible connectors and thereby separate the pipes from one another.</p> |
