MECHANICAL CONNECTION OF PIPES OF MAIN PIPELINES Russian patent published in 2021 - IPC F16L19/00 

FIELD: oil and gas production, oil and gas processing, chemical, metallurgical industries.

SUBSTANCE: invention relates to the design of a device for connecting pipeline systems and can be used in connecting pipes of extended main pipelines for the transportation of water, oil, natural gas, other liquids and gases in the oil and gas production, oil and gas processing, chemical, metallurgical industries and other areas. The connection is carried out by tightening and uniform double-sided crimping of the conical parts of the pipe walls with the help of a conical connecting nipple sleeve and two spanning split multi-link tracks, as well as tightening pins, nuts and washers, which ensure its structural unity and strength. In this case, the sealing and impermeability of the connection is carried out on the inner conical surfaces of the pipes and the conical parts of the nipple sleeve.

EFFECT: invention provides a minimum assembly time, high accuracy and quality of connection of pipes of main pipelines even in difficult weather conditions on the ground, in trenches, on overpasses, in cramped tunnels and rooms, as well as under water.
