Hydraulic Acticated Landing Collar With Ball Catcher Sub

The hydraulically activated landing collar with ball catcher sub is used when running hydraulic-set liner hangers or other hydraulic-activated components in a liner string. A setting ball lands in the ball seat allowing pressure to be applied to the hanger to set the slips. This releases the hydraulic running tool from the liner at a higher pressure before shearing the pre-installed shear pins and removing the seat from the flow path. A retained ball-seat design prevents the sheared-out cage and ball assembly from interfering with float equipment installed below the landing collar. Large milled slots provide an unrestricted flow area while cementing. Internal components are constructed of wrought aluminum and are compatible for drillout.
