METHOD OF RUBBER-CORD BRANCH PIPE ASSEMBLY Russian patent published in 2015 - IPC F16L33/22 

FIELD: machine building.

SUBSTANCE: invention refers to rubber-cord branch pipe design and assembly method, particularly, to high pressure branch pipes, and can be used in rubber-cord branch pipe manufacturing in different industries. The edge of cord base layers and of rubber sealing layer is preliminary folded onto the cylindrical tool, an attachment flange with annular boring is set on the end of the cylindrical tool, the edge of the cord base layers and the rubber sealing layer is laid onto the flange. Afterwards the cord base layers and the rubber sealing layer are laid into the annular boring of the attachment flange, semi-rings are installed, clamped by a ring, and the semi-rings and the ring are fixed to each other.

EFFECT: provision for reliability and sealing of the bead zone of the rubber-cord branch pipe flange in the wide range of pressures of the medium being pumped.
