  • Shear ram assembly
    Patent number: 6719042
    Abstract: The shear ram assembly 10 for shearing an oil well tubular T includes a first ram 16 axially moveable along the first axis 66 for moving an upper blade 17, and an opposing second ram 18 axially moveable along the second ram axis 68 for moving a lower blade 19. An upper planar surface 40 of the lower blade passes closely adjacent a lower planar surface 42 of the upper blade as the blades move towards each other to shear the tubular. The sealing system 24 is positioned within a recess 26 in the upper surface of the lower blade, and includes an elastomeric seal 28 for sealing engagement with the lower planar surface of the upper blade and a rigid actuator 30 moveable relative to the lower blade to energize the elastomeric seal.
    Type: Grant
