US Patent 11189412 Inline demagnetization for operational pipelines

Systems, methods, and a computer readable medium are provided for demagnetizing a pipe within an operational pipeline. An inline demagnetization device can be positioned in a first location within a pipe of an operational pipeline. The inline demagnetization device can be positioned via a plurality of positioning mechanisms operable to position the inline demagnetization device at one or more locations within the pipe. The inline demagnetization device can transmit magnetic fields into the pipe at the first location via a plurality of magnetic field conductors configured within the inline demagnetization device. The transmitted magnetic field can cause a reduction of magnetization present in the pipe. The inline demagnetization device can be positioned in a second location to further reduce the magnetization present at the second location.
