Primenenie vnutritrubnykh ustroystv dlya razmagnichivaniya metalla lineynoy chasti stal"nykh truboprovodnykh sistem razlichnogo naznacheniya yavlyaetsya bolee effektivnym, chem ispol"zovanie sushchestvuyushchikh ustroystv razmagnichivaniya lokal"nykh uchastkov truboprovoda. V rabote privedeny rezul"taty issledovaniy po sozdaniyu optimal"nykh mnogopolyusnykh magnitnykh sistem ustroystva vnutritrubnogo razmagnichivaniya stal"nykh truboprovodov (UVR), kotorye osnovany na simmetrichnykh i nesimmetrichnykh tsiklakh peremagnichivaniya metalla. Na osnove issledovaniya magnitnogo sostoyaniya metalla stal"nogo truboprovoda s ostatochnoy namagnichennost"yu ustanovleny predel"nye znacheniya ryada magnitnykh parametrov dlya konstruktsionnykh staley, ispol"zuemykh v magistral"nykh truboprovodakh. Na baze etikh predel"nykh parametrov osushchestvlen teoreticheskiy raschet i analiz optimal"nykh parametrov magnitnoy sistemy razmagnichivayushchego ustroystva UVR. Privedennye rezul"taty sravnitel"nykh laboratornykh i stendovykh ispytaniy maketov UVR, osushchestvlyayushchikh razmagnichivanie metalla stal"nogo truboprovoda po simmetrichnomu i nesimmetrichnomu tsiklu peremagnichivaniya metalla pokazyvayut ikh effektivnost" i rabotosposobnost".
