BLAST SYSTEM FOR REGENERATING A SUPERANNUATED PIPE

摘要

The present invention relates to a blast system for regenerating a superannuated pipe. According to the present invention, the blast system for regenerating a superannuated pipe comprises: a traveling robot for surface process which includes a variable arm including a plurality of blasting guns capable of controlling the length to correspond to the diameter of pipe to perform a process for forming roughness on an inner surface of a superannuated pipe before painting; and a blast device collecting a grinding material and a foreign material generated when the roughness is formed on the inner surface of the cylindrical superannuated pipe using the traveling robot, separating the collected foreign material, and inserting the grinding material into the inner surface of the superannuated pipe. Therefore, the blast system for regenerating a superannuated pipe can reduce the entire height by including, as an unit for a plurality of blast devices with different functions from each other, an independent device separated into moving vehicles for each function rather than an integrated device using a single moving vehicle, thereby being applied to a pipe with various diameters when compared with the conventional one and increasing productivity with a traveling robot for process for surface of the superannuated pipe with a multi-blasting gun for large capacity.
