<p>PURPOSE: An apparatus for cooling the inside of a pipe is provided to spray cooling water on the inner surface of the pipe, since a fluid supply unit is accurately placed in the same axis with a center axis. CONSTITUTION: An apparatus for cooling the inside of a pipe comprises a fluid supply unit(100), a cooling water nozzle(200), a compressed air nozzle(300), a positioning unit(400), and a controller(500). The fluid supply unit is formed in the form of a double pipe. A cooling water inlet(121) is formed in an outer pipe(120). A compressed air inlet(111) is formed in an inner pipe. The cooling water nozzle is formed in the form of a circle and sprays the cooling water. The compressed air nozzle is adjacent to the cooling water nozzle. Multiple wheels(410) of the positioning unit are contacted with the inner surface of the pipe. The height of the positioning unit is adjusted to position fluid supply unit in the same axis with the center axis of the pipe.</p> |
