APPARATUS FOR HEAT-EXCHANGING APPARATUSES PIPE LATTICES PIPES ELECTRICAL PULSE EXPANSION Russian patent published in 1996 - IPC

FIELD: heat-exchanging apparatuses pipe lattices pipes coupling. SUBSTANCE: 1. Apparatus for heat-exchanging apparatuses pipe lattices pipes electrical pulse expansion has cylindrical body filled with conducting medium, located in the body explosive member and sealing insert. Apparatus differs from others by the fact, that to expand simultaneously several side by side located pipes it has several bodies joined into one detail by loose located flexible jumpers, that are capable for deformation. 2. Apparatus is corresponding to point 1 and differs from it by the fact, that explosive members are connected to each other by conducting jumpers, that form common conductor. 3. Apparatus is corresponding to point 1 and differs from it by the fact, that to avoid burnings on pipe surface explosive members negative terminals are placed at pipe lattice butt. EFFECT: increased productivity, efficiency and quality of treated couplings.
