DEVICE FOR SCANNING PIPE GEOMETRY Russian patent published in 2023 - IPC G01B7/00 

FIELD: measuring equipment.

SUBSTANCE: invention relates to the field of studying a technical condition of long-length pipes. Control of a technical condition of a long-length pipe is carried out by passing it through a stationary device, in a case of which a node for scanning a diameter and ovality is placed, including stationary sensors. A curvature control node includes three sensors located above one generatrix of the scanned pipe, one of which is installed at an input of the device, the other – at an output, and the third one is placed between the first two. It is possible to determine curvature of an object in several diameter measurement planes. Thus, the sensor is included in both the node scanning a diameter and ovality and the curvature control node, which provides measurement of curvature of the studied pipe. At the input and the output of the device, there are centralizers evenly located around the pipe and containing centering rollers, one of which is directly connected to a sensor of a node for measuring of a pipe length.

EFFECT: determination in a real time mode of a radius of curvature of a controlled pipe and obtainment of results of diameter and ovality measurements.
