Shearing blind rams are designed to cut through drill pipe and shut in a well control situation. Shearing blind rams (blind shear rams) are designed to completely seal off a well after the pipe is cut, or sheared, controlling pressure.
Variable Bore Rams, Inc. carries bore ram sizes from 7-1/16 inches to 21-1/4 inches for LWS, LXT, NXT, SL and SLX ram BOPs.
