Kelly Bars Manufacturing
Kelly bar is the key element of the rotary drilling rig that transfers the torque and the pull-down from the rig to the drilling tool. The kelly bar comprises of high strength but ductile telescoping steel tubes with special guide strips, drive strips, pull-down keys and locking elements welded onto the steel tubes.
The gearbox of the drilling rig engages the drive strips and the pull-down keys of the outermost tube to apply the torque and the pull-down respectively to the kelly bar while the locking element on the inside of any given tube engages the drive strips and pull-down keys of the next inner tube to transfer to the inner tube the same torque and pull-down. This transfer of torque and pull-down proceeds from the outermost tube to the innermost one which has a square drive stub at its lower end that connects to the drilling tool.
