AN APPARATUS FOR REMOVING FLASH FROM THE INSIDE SURFACE OF WELDED PIPED Abstract of the Disclosure An apparatus comprises a body mounting V-shaped two- arm levers. Around the periphery of the body there are disposed cutting tool holders pivoted each to one arm of each of the levers. On the body there are mounted drives for turn- ing the levers, each of said drives being connected with the other arm of each of said levers. On the front ends and the rear ends of the cutting tool holders there are mounted rollers which are in contact with the inside sur- face of the pipe. The cutting tool holders hold cutting tools rigidly secured thereto. Such an arrangement of the apparatus of the present invention makes it possible to increase the period between repairs several times, to appreciably reduce the power consumption and engine power required for the movement of the apparatus within pipes, and to substantially rule out the possibility of damaging the pipe walls and weld in the course of flash removal.
