ABSTRACT:
A method and apparatus for destabbing (disassembling) two vertically oriented drill pipe joint sections provides a two part clamp arrangement that holds the assembled joint at their interface. A lower end of the clamp arrangement is tightly clamped to the lower joint so that the upper joint rotates when the two joint are gripped with power tongs or like pipe handling devices and unthreaded or "destabbed".
