ELECTRICAL EXPLOSIVE CARTRIDGE FOR PIPES FIXATION IN PIPE LATTICES OF HEAT-EXCHANGING APPARATUSES Russian patent published in 1996 - IPC

FIELD: pipes coupling. SUBSTANCE: 1. Electrical explosive cartridge for pipes fixation in pipe lattices of heat-exchanging apparatuses has body with step on outer surface used as stop for pipe butt filled with conducting medium and also located in body along axis of cartridge in series connected to each other current conducting members: explosive member contacting by its free end with pipe, and unexplosive member connected by its other end with outer electrode. It is distinguished by the fact, that to increase quality of pipe fixation due to avoiding burning on its inner surface contacting pipe end of explosive current conducting member is terminated at step of body. 2. Electrical explosive cartridge is corresponding to point 1 and differs from it by the fact, that electrical explosive member is made of two parts: one - made in the form of piece of wire located along axis of cartridge and another, that has cylindrical form and embraces the piece of wire. 3. Electrical explosive cartridge is corresponding to points 1, 2 and differs by the fact that cylindrical part of electrical explosive member is made in the form of cylinder with flange terminated at step of body and axial piece of wire is connected with bottom of cylinder. 4. Electrical explosive cartridge is corresponding to points 1, 2, 3 and differs by the fact that cylindrical part is made of unexplosive film, for example, of layer of current conducting paint. 5. Electrical explosive cartridge is corresponding to points 1, 2 and differs by the fact that cylindrical part of explosive current conducting member is made in the form of spiral, one end of which transforms into axial piece of wire and another is terminated at step of body. EFFECT: improved pipes coupling.
