IN INNER TUBE OF WATERWORKS TUBE WASHING SYSTEM AND WASHING METHOD

摘要

An apparatus and a method for washing an inner pipe of a public water pipe are provided to improve workability and to reduce the cost for washing equipment by removing sediments stacked in the inner pipe using a ductile and a valve. An apparatus for washing an inner pipe of a public water pipe comprises a first ductile(21) and a second ductile(21'). A negative magnet plate(22) is attached to a bottom surface of a pipe path(A) and a magnet(M) coupled with a positive magnet rod is inserted into a flange of the second ductile by using a clip(C). An air hole is formed in the positive magnet rod and a pig(40) is inserted into the first ductile to seal the flange of the second ductile. First and second valves(51,51') are installed in the public water pipe to wash the inner pipe using water pressure in the pipe path.
