Pipe flaw detection equipment

The invention belongs to the technical field of ship equipment, and discloses pipe flaw detection equipment which comprises a pipe clamp and a pipe positioner. The pipe body position changing machine comprises a position changing machine base, a supporting seat, a rotating wheel and a pressing mechanism. The supporting seat is mounted on the positioner base and can rotate relative to the positioner base; the rotating wheels are rotationally connected with the supporting base, the two rotating wheels are arranged in parallel and rotate in the same direction, and the pipe body clamp is arranged on the two rotating wheels. The pressing mechanism is installed on the supporting seat and comprises a pressing wheel, the pipe body clamp is clamped between the pressing wheel and the two sets of rotating wheels in a rolling mode, and under the action of friction force, when the rotating wheels rotate, the pipe body clamp can generate circumferential rotation along with the rotating wheels, so that circumferential adjus
