摘要 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.
