PURPOSE: A correcting device of pipe and a subsidiary correcting device of the pipe are provided to prevent strength deterioration of the pipe and reduce material waste of the pipe by correcting a part of the pipe which is bent or severely crumpled to the original state. CONSTITUTION: The correcting device of pipe comprises a tripod shaped support(1); a body installed on the support; a horizontal stand(2) horizontally installed on the body(3); supporting rollers(4) installed at both ends of the horizontal stand; an eccentric roller(5) installed on an upper part of the body; and a handle(6) for rotating the eccentric roller, wherein the eccentric roller comprises eccentric shaft, inner roller and roller case. The subsidiary correcting device of pipe comprises a connection part inserted into the pipe to be connected to the pipe; a hitting part which is installed in such a way that the hitting part is reciprocated on an outer surface of the connection part, and which provides impulse to the connection part so that the connection part is inserted into the pipe; and correction part and projection part installed at opposite sides of the connection part to straighten a connection region of the pipe which is crumpled.
