PROBLEM TO BE SOLVED: To enhance the washing effect of a pipe to be washed as compared with a conventional washing apparatus and to stably and efficiently wash the pipe without generating irregularity in quality even when a fine caliber long pipe is washed. SOLUTION: A washing cylinder 3 is immersed in the washing soln. 4 within a washing tank 2 to be vertically arranged and a compressed air generating means blowing in compressed air from the lower end opening part of the washing cylinder 3 is installed and an air bubble soln. low in specific gravity is generated by the compressed air generating means to generate the high speed rising flow of the air bubble soln. within the washing cylinder by the specific difference with the soln. outside the washing cylinder. A hydrocarbon type surfactant washing agent is used in the washing. soln. Further, a bottomed cylindrical cartridge having a metal net arranged to its bottom part and permitting the insertion of a plurality of pipes P to be washed in a bundled form is provided to be inserted in the coaxial interior of the washing cylinder 3. |
