ONE-PIECE CONNECTION OF HIGH-PRESSURE HOSES Russian patent published in 2022 - IPC F16L33/00 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to mechanical engineering for the production of reinforced flexible high-pressure pipelines. The non-detachable connection of the high-pressure hose contains a hose consisting of a sealing layer and a force layer based on an aramid rope impregnated with an elastomeric binder. A nipple with annular sealing protrusions made in the zone of the sleeve's power seal, with a groove on the outer surface and a crimping layer in the zone of the sleeve's sealing. In this case, the nipple in the sealing zone of the sleeve's strength layer is made in the form of a truncated cone with apex towards the sleeve with a cone angle of 6-10° with a rounding in the transition zone of the base of the cone and the generatrix. In the zone of sealing the sleeve sealing layer, the nipple is made thin-walled with annular protrusions and depressions. Moreover, the sealing annular protrusions and depressions in the sealing zone of the sleeve sealing layer are made in the radial and axial directions in the body of the nipple.

EFFECT: increasing the reliability of the connection of high-pressure hoses.
