What is non Intrusive Magnetic Pig Signaling? and how it is performed?

Non-intrusive magnetic pig signaling is a technology used to detect the passage of magnetic pigs within a pipeline without the need to penetrate or interrupt the flow of the pipeline fluid. This is achieved by utilizing magnetic fields to detect the presence of the pig, offering several advantages over traditional intrusive methods.   How Does it Work? 1. Magnetic Pig: A magnetic pig is equipped with permanent magnets or a magnetic transmitter.   2. Non-Intrusive Signaller: A sensor, typically mounted externally on the pipeline, detects the change in the magnetic field caused by the passing pig.   3. Signal Transmission: The sensor transmits a signal to a remote location, indicating the pig's passage.   Advantages of Non-Intrusive Magnetic Pig Signaling 1. No Pipeline Interruption: The non-intrusive nature eliminates the risk of leaks or contamination associated with intrusive methods.   2. Reduced Maintenance: As there are no moving parts in contact with the pipeline fluid, maintenance requirements are minimal.   3. Increased Safety: Eliminates the need for personnel to work directly on the pipeline, reducing safety hazards. 4. Cost-Effectiveness: Lower installation and maintenance costs compared to intrusive methods. 5. Versatility: Suitable for a wide range of pipeline sizes and materials. Applications of Non-Intrusive Magnetic Pig Signaling 1. Pipeline Integrity Inspections: Detecting the passage of inspection pigs used to assess pipeline conditions.   2. Cleaning Operations: Monitoring the progress of cleaning pigs used to remove debris or deposits. 3. Batch Tracking: Tracking the movement of different product batches within a pipeline. 4. Leak Detection: Identifying potential leaks based on changes in pig travel time. Video Credit: All rights are reserved to the owner(s) of this video
