DETONATING TUBE Russian patent published in 2015 - IPC C06C5/04 F42B3/10 F42D1/04 

FIELD: blasting operations.

SUBSTANCE: invention relates to detonating cords and can be used for accurate in time transfer of detonation to the explosive charges in devices of spherical implosion of explosion. The detonating tube comprises a shell and a charge of high explosive, at that the shell consists of two layers, namely the inner thin-walled layer of a polymer with a melting temperature higher than the melting temperature of the outer thick-walled layer. On the inner surface of the outer layer there are longitudinal, along the axis of the tube of the rib, inclined at an angle to the radius of the tube and the thickness of the ribs less than the wall thickness of the inner layer of the shell. There is vacuum between the layers.

EFFECT: solution provides transmission of detonation from the primary detonator to the secondary detonator, without causing predetonation of the explosive.
