The invention provides a disengagement-prevention jig for steel pipes. The jig comprises a cross beam. The middle of the cross beam is connected with a lifting ring through a vertical beam. The two ends of the cross beam are connected with lifting tools through rotating shafts respectively. The lifting tools are composed lifting jaws, left positioning plates and right positioning plates, wherein the left positioning plates and the right positioning plates are connected with the lifting jaws. The left positioning plates and the right positioning plates are provided with screw rods, arc fixing plates are arranged at the inner side ends of the screw rods, the bottom ends of the lifting jaws are arc, and electromagnets are arranged in the lifting jaws. According to the disengaging-preventing jig for steel pipes, steel pipes with different pipe diameters can be carried conveniently, fixing is convenient and firm in the carrying process, the steel pipes can be firmly fixed through the fixing plates on the two sides of the lifting jaws, disengaging of the steel pipes can be avoided in the carrying process, the quality of the steel pipes is ensured, and disengagement of the steel pipes can also be prevented.
