SAG PIPE COUPLING Russian patent published in 2010 - IPC F16L55/18 F16L55/168 F16L55/17 F16L55/175

Abstract RU 2378560 C1

FIELD: machine building.

SUBSTANCE: invention is related to devices for repair of pipeline sections, including submerged crossings, without interruption in product transit. Coupling consists of two half couplings and nozzles for supply of composite compound. Upper half coupling is equipped with indicator nozzles, fastening brackets, mechanism for control of vertical position of reservoir. Mechanism consists of basket for installation of reservoir with composite compound, barrel, ring, hinged nut, support, stop bush, ball valve, short coupling, lock-nut, coupling cover, needle. Lower half coupling comprises positioning pins, which join upper and lower half couplings, dog bolts, mount bolts, fastening chain, yokes, rubber seals. Reservoir for composite compound consists of balloon and inbuilt heat removal system, including radiator, bus bars, supports. Coupling is installed onto repaired section of pipeline, filled with composite compound, matured until complete hardening.

EFFECT: strengthening of corroded or damaged section of pipeline, increased reliability of pipeline operation.
