In an effort to reduce potential injuries we've implemented using air slips since 2010. Gilliss Casing Services is implementing Air slips for all strings of pipe ranging from 2 3/8″ to 7″. We believe that this method reduces pinch points between the conventional slips and the elevators. As well, we feel this will eliminate back injuries completely. All pneumatically controlled units operate using rig air. The slips can be manually operated if rig air pressure is lost. Safety is further ensured by a positive locking mechanism which locks the slips in the set position. Incidents have occurred where pipe was lost down the hole due to both human and mechanical error. The Type E pneumatic air slips, are constructed in such a way that they can be opened & closed to allow the pipe to be moved in either direction. The slip body cannot be removed from the pipe unless the gate is physically removed. This feature will prevent the slips being removed from the rotary table, due to accidental hoisting of casing; either by elevators catching the collar while picking up the next joint, or if the pipe hydraulics.
