영문 초록

Scale is generated by foreign matter stuck to the inner wall of the pipe by various phenomena arising from the water pipe. These scales, it is solidified after a long time, causing to narrow the flow path of the pipe. Various techniques associated with the foreign substance removal inside these pipes have been proposed, but had no effect. Just be generated only leak, the need for cleaning of the other methods have been requested. In this study, the present invention relates to new technology is a high-pressure nitrogen in the cleaning system is on the inside of the pipe at the time of the cleaning effect of chemistry and high-pressure washing of water piping. Safety, impact pressure, cleaning efficiency such as a result of the experiment, high pressure nitrogen(3.0MPa(35   ) is hight by disruption and the point type when introduced into the pipe, rust, cleaning effect of the chemical action of the sludge are rapid freezing phenomenon XL, PB pipe 96 %, copper 90%, steel pipe 85%. Although air leakage occurs at approximately 1.0 MPa, nitrogen safety no leakage occurs even 3.5 MPa was demonstrated. In addition, the effect of the pressure of the length of the pipe cleaning is on, the pressure is transmitted to the first and last part, was a very effective system for high pressure cleaning.
