JOINT OF REINFORCED POLYMER TUBE Russian patent published in 2016 - IPC F16L21/00 

FIELD: pipe.

SUBSTANCE: invention is intended for connection of various types of polymer pipes, hoses, hoses, profiles, primarily, reinforced, or for jointing polymer tubes and metal tubes or metal fittings. Pipe connection assembly consists of bearing sleeve arranged inside pipe and equipped with a stop collar, restricting movement of pipe, as well as a cylindrical clamping split sleeve having locking groove for connection with locking collar on inner surface and covering outside pipe and bearing sleeve. Inner surface of parts of split sleeve is equipped with uniformly distributed, alternating radial flanges or crimping rings and grooves. Clamping sleeve is additionally equipped with stop rings enveloping its outside, with possibility of fixation of segments of its components in closed state, as well as uniform reduction and fixation of annular projections of clamping sleeve position of pipe and its reinforcing elements of system in connection assembly throughout mating surface of bearing sleeve and clamping sleeve.

EFFECT: technical result consists in ensuring uniformity of reduction of the pipe and hence uniform reduction of reinforcing system and improvement of reliability of fixing tubes in connection assembly.
