FIELD: thermal and atomic power stations.
SUBSTANCE: the invention is dealt with mechanical cleansing of tubes of steam-turbine condenser of thermal and atomic power stations. The cleansing member consists of four thin and hard plastic rings, two of which have by two grooves on their outer sides and their depth equals to 1/2 of each ring width, and other two rings have by similar two grooves, but located on their inner sides. Two first rings are inserted into internal grooves of the second pair having formed a set of the four interlinked rings, inside which a soft and resilient bead is inserted with a diameter of exceeding the inner diameter of the rings and with an incision for fixation of the rings. At that the rings are uniformly located along the circumference. Moving in the subjected to cleansing tubes the cleansing member touches them by its pointed ridges and scrapes off not only soft sediments, but also the germs of still not grown stronger crystals, rigid carbonate deposits, preventing their new formations.
EFFECT: the invention ensures effective cleansing of tubes.
