FIELD: valving.

SUBSTANCE: self-sealing pipe junction comprises nipples that are in a contact one with the other, means for junction made of lock nut, and compensators mounted at the end of each pipeline. Each compensator is made of ring spherical member. The radii of curvature, the widths, and the diameters of the rings are the same. The nipple of each pipeline is made of conical section whose small diameter engages the ring spherical member. The large diameter of the conical section of the first nipple engages the disk secured to the first pipeline and is positioned perpendicular to it. The large diameter of the conical section of second nipple engages the corner flange whose side is perpendicular to the second pipeline and secured to it.
