BENDING DEVICE FOR FLEXIBLE TUBING STRING (EMBODIMENTS) Russian patent published in 2025 - IPC E21B19/22 

FIELD: machine building.

SUBSTANCE: group of inventions relates to embodiments of bending device for flexible tubing string. Bending device for flexible tubing string provides a channel with a near end and a far end opposite said near end. Said near end is located relative to said far end so as to form a bending angle of said channel. Said channel comprises a curved section with an injector end directed towards said near end, and a drum end directed towards said far end opposite said drum end. Said injector end is arranged relative to said drum end to form a flexure angle of said bent section. Flexible section provides a first flexible end directed towards said proximal end, and a second flexible end directed towards said far end opposite to the first flexible end. Said first flexible end is arranged relative to second flexible end so as to form an adaptive bending angle of said flexible section. Said channel bending angle provides for said bending angle and said adaptive bending angle. Said adaptive bending angle is smaller than said bending angle. Mounting appliance is secured to said near end of said channel. Said mounting tool provides a mounting plate at the proximal end and a mounting base with a swivel to said mounting plate. Joint rotation of said channel and said mounting plate relative to said mounting base is possible.

EFFECT: providing safe and reliable device for supply of flexible tubing string to the well head.
