AGGREGATE FOR PIPES FIXATION IN PIPE PLATES OF HEAT-EXCHANGING APPARATUSES Russian patent published in 1996 - IPC

FIELD: pipes coupling. SUBSTANCE: 1. Aggregate for pipes fixation in pipe plates of heat-exchanging apparatuses has pulse currents oscillator with two terminals of positive and negative polarity connected by electrodes to be mounted in pipes electrical explosive cartridges. Characteristic feature of aggregate is that to increase its efficiency and productivity two terminals are connected in series to beginning of first and to end of last of two wire electrodes. In the case number of in series connected electrodes is determined on the base of condition of critical discharge production. 2. Aggregate corresponding to point 1 differs from it by the fact, that to use explosive cartridges with terminals contacting with pipe lattice, each two cartridges are mounted in separate isolated from others heat-exchanger. 3. Aggregate corresponding to point 2 differs by the fact that each electrode has autonomous system of motion. EFFECT: improved efficiency and productivity of aggregate.
