FIELD: pipe radiators production. SUBSTANCE: apparatus for pipe radiators expansion by electrical pulse has metal conductor, dielectric bush with bead and mounted in bush from bead side current lead made in the form of rod with cross-section bigger then cross-section of metal conductor and with length bigger that length of bead. In the case dielectric bush and metal conductor have mainly equal length and are shifted in axial direction in respect to each other. They are differed by the fact, that to protect unexpended couplings and to clear radiator case from explosion products dielectric bush bead is mounted in fully isolated bush with protecting metal body and with length bigger than space between pipe lattice and front wall of radiator case. EFFECT: method allows to protect unexpended couplings from explosion products, increases quality of expansion. 1 dwg
