Shear ram blowout preventer
Patent
·
OSTI ID:6784416
There is disclosed a ram type blowout preventer having a pair of shear rams adapted to shear pipes suspended in the bore of the preventer and subsequently seal off the bore. The rams utilize a transverse packing for sealing between the shear blades when they are closed. One shear ram has a ramp adapted to engage a shoulder on the opposing ram so as to urge the shearing blades closer together as they are closing and thereby reduce the vertical gap which the transverse seal must bridge.
