  • Pipe grapple
    Patent number: 8708038
    Abstract: A grapple for controlling, monitoring and stopping the flow of oil, natural gas and the like from a broken, flanged pipe. A housing encloses a ring of material that is more ductile than the broken pipe flange. The force applied by a weight, presses a driving device against the broken pipe flange periphery, the force so applied distorts the ductile ring, thereby establishing a fluid-tight seal between the flange and the housing.
