DEVICE FOR ELIMINATING DEFECTS IN METAL STRUCTURE ON THE INNER WALLS OF PIPELINES BY MAGNETIC PULSE TREATMENT Russian patent published in 2023 - IPC B23P6/00 C21D9/08 H05B6/36 C21D1/42 F16L53/34 

FIELD: metallurgy.

SUBSTANCE: devices for magnetic pulse processing of metals, and is intended to eliminate hard-to-reach defects in the metal structure during the manufacture and operation of pipelines in the oil and gas industry. The device contains a housing made in the form of a thick-walled cylinder, in the walls of which the current winding is located. The current winding is removably placed in two diametrically opposed screw channels made on the outer surface of the housing walls. At the ends of the current winding there are pins installed in the through holes of the housing with the possibility of connecting to a magnetic-pulse installation. There are cavities on both sides of the body, in each of which a support in the form of a sphere is installed with the possibility of rotation. Between the supports in the body there are rectangular cavities with through holes opposite each other, in which wheels are installed, which have external protection made of composite materials. Inside the case there is a mount for the radio control system, secured to the inner surface of the case with clamps. The specified mount contains a radio control system consisting of a battery, the outputs of which are connected to the inputs of the Arduino board and the driver inputs. The input of the Arduino board is connected to the output of the Bluetooth board, and its outputs are connected to the input of the Bluetooth board and the driver inputs, the outputs are connected to the stepper motors inputs. To each stepper motor a rotatable shaft of the radio control system is attached, on which a gear of the shaft of the radio control system is fixed with the ability to interact with the gear of the wheel shaft, installed perpendicular to it at the end of the wheel shaft.

EFFECT: eliminating defects on the inner surface of pipelines, increasing their service life.
