SLIP AND ELEVATOR RECESSES
Slip and elevator recesses are designed to cut drill collar handling time by eliminating lift subs and safety clamps. Slip and elevator recesses may be used together or separately.
HARDBANDING
Drill collar hardbanding is the most effective way to reduce the OD wear that occurs on a drill collar under normal drilling conditions. Please contact us to inquire about the broad selection of hardbanding options.
