PURPOSE: An apparatus and method for removing weld beads on a pipe with a mandrel, and the pipe manufactured thereby are provided to reduce cost by using cutting water instead of cutting oil, and to prevent the corrosion of the pipe. CONSTITUTION: An apparatus for removing weld beads on a pipe is composed of oil pressure generators(210,310,410) coupled to a driving unit(600) and clamping the pipe, a cutting unit inserted into the inside of the pipe and cutting the weld beads, and water pressure generators(610,620,630) coupled to the driving unit. The water pressure generators apply water pressure to the cutting unit, and forcibly insert the cutting unit to the pipe.
