It is difficult to remove it that has adhered to the inner surface of the raw pipe, and the cutting powder that has adhered to the inner surface of the raw pipe during dip coating moves into the coating liquid and forms a photosensitive layer on the raw pipe. It was mixed in the photosensitive layer and appeared as a black dot defect on the image.

る。When an organic solvent is used, it is necessary to collect and treat the solvent vapor and treat the waste liquid. Further, many organic solvents cause poisoning symptoms and are harmful to the human body. On the other hand, when a detergent is used, a washing step and a rinsing step are required, and the apparatus becomes large, which requires a long time for washing. In addition, it is necessary to treat the waste detergent.

る。これは、外周面の場合も同様である。BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. In the present invention, high pressure water is used in place of the detergent or the like in the high pressure washing step. FIG. 1 is a diagram schematically showing how high-pressure water is jetted onto the surface of a raw pipe to perform cleaning. As shown in the figure, high-pressure water 4 is jetted toward the inner peripheral surface of the raw tube 1 from a high-pressure nozzle 3 located at a distance L from the inner peripheral surface S. This also applies to the outer peripheral surface.

る。The pressure of the high-pressure water 4 at this time is usually 30 to
It is set in the range of 300 kgf / cm 2 . The distance L from the high pressure nozzle 3 to the surface of the raw tube 1 is usually set in the range of 10 to 200 mm. Further, the amount of water discharged from the high-pressure nozzle 3 needs to be 4 l / min or more.

That is, even if the pressure is set to 200 kgf / cm 2 or more, the cleaning effect does not change so much. Also, if the pressure is too high,
There is a risk that the surface of the raw tube 1 may be damaged.

果を得る事ができる。Further, in this embodiment, a high effect is obtained by setting the distance L in the range of about 50 to 100 mm. In other words, it is not necessary that the injection positions be close to each other, but it can be said that the high pressure water 4 entrains the surrounding air and increases the impact force by keeping a certain distance. In this embodiment, the high pressure nozzle 3
1 has an injection divergence angle of 15 ° indicated by α in FIG. The high-pressure water 4 used in the present invention can obtain a higher cleaning effect if it contains less impurities. When the content ratio of the impurities is expressed by the specific resistance, the high-pressure water needs to have 10 kΩ · cm 2 or more. When the high-pressure water 4 has a specific resistance of 10 × 10 5 Ω · cm 2 or more, a higher cleaning effect can be obtained.

装置等が不用であるので、装置の小型化が可能である。As described above, in this embodiment, a strong cleaning power can be obtained only by using high-pressure water as the cleaning liquid, and the ultrasonic cleaning step and the brush cleaning step can be omitted in some cases, and the cleaning time can be shortened. It can be shortened. In addition, since neither organic solvent nor detergent is used, it is harmless to the human body and environmentally friendly. Further, since a complicated process for cleaning and an auxiliary device therefor, such as the above-mentioned rinsing process and a device therefor are unnecessary, the device can be downsized.
