PIPELINE GUIDE DEVICE Russian patent published in 2025 - IPC F16L39/06 F16K5/06 

FIELD: pipeline transport.

SUBSTANCE: invention relates to pipeline transport and is intended for redirection of in-line pigs and flaw detectors along two sections of the pipeline without stopping the flow of medium through the main pipeline, without the need to install chambers for starting and receiving cleaning and diagnostics facilities with pipeline connections. Device comprises a housing with three nozzles of the same diameter D. Two outlet branch pipes are arranged at an angle to each other symmetrically relative to the axis of the inlet branch pipe. Body is made in the form of a cartridge with an inner surface in the form of a straight cylinder and a flat round bottom. Swivel inserted into it is made in the form of a sleeve with a cylindrical outer surface and a flat bottom, with sealing devices between the cylinders. Housing cylinder is connected to the holes by the corresponding outlet branch pipes. Inlet branch pipe is connected to the hole in the centre of the bottom circle. In the centre of the swivel bottom there is an inlet hole connected to the inlet of the curved perforated passage of the swivel, the outlet of which is located on the cylindrical surface of the swivel. Outlet of the fluid discharge channel from the area behind the perforation is located symmetrically relative to the axis on the cylindrical wall of the swivel.

EFFECT: higher reliability and maintainability.
