The invention relates to a clamp capable of being used for vertically hanging steel pipes. The clamp is provided with a plurality of arc plates, wherein the arc plates are connected into a sealed circular ring structure through a press tongue shaft arranged among the arc plates, a press tongue is pivoted on the press tongue shaft, the bottom force arm of the press tongue is a flat end, and a press tongue tooth extends from one end of the bottom force arm towards the upper edge. The clamp has the advantages that the self weight of the steel pipes can be used for enabling the press tongue of the clamp to freely and tightly press the steel pipes, and in addition, the vertical steel pipes can be hung up; after the steel pipes reach the proper position, when a slide rope is pulled by force, the self weight of the clamp can be used for releasing the press tongue, in addition, after the falling to the convenient-to-operate height along with the descending of a crane, a steel wire rope is hung in a hook, the clamp can be lifted, and release of a hanging machine is also realized. The problem that a hanging point needs to be welded and dismounted during the steel pipe hanging is solved; the materials are greatly saved, the hanging efficiency is improved, and the adverse influence caused on the steel pipes is avoided.
