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.
Claims8
A grapple for controlling flow from a pipe with a transverse flange having a circular periphery comprising, a housing having a cavity formed therein, said cavity having a transverse diameter that is greater than the periphery of the flange, a deformable ring within said housing having said ring overlapping the flange periphery for selective contact between said ring and the flange, said ring being formed of a material that is more ductile than the flange, at least one weight for applying a force to the flange that is sufficient to deform said ring, and at least one driving device for bearing said weight and for pressing said flange against said ring.
