Abstract
A pipe joint location detection system includes a main body, at least one magnet, and a plurality of magnetic sensors. The main body has an annular shape defining a central passage, the at least one magnetic is coupled to the main body, the magnet is configured to output a magnetic field, and the plurality of magnetic sensors is coupled to the main body and disposed about a circumference of the main body, wherein each magnetic sensor of the plurality of magnetic sensors is configured to detect a magnetization of a tubular string disposed within the central passage. The pipe joint location detection system also includes a memory comprising data stored thereon, wherein the data includes a first magnetization value associated with a first contour of the tubular string and a second magnetization value associated with a second contour of the tubular string, wherein the first contour is different from the second contour.
