How INGU Pipers® Conduct Magnetic Feature Detection
Advantages of Using Pipers® for Magnetic Feature Detection
-
Valuable insights
Identify air release valves, couplings, and any other metallic elements on your pipeline.
-
Non-intrusive inspection
Pipers® do not require cleaning of your pipelines before the inspection and can be deployed under operational conditions, making the inspection process seamless and non-intrusive.
-
GIS visualization
Inspection results can be presented in the INGU Interactive Pipeline Viewer, making it easier to verify reported outliers.
-
Comprehensive data analysis
Our AI-powered data analytics deliver precise and reliable results, transforming raw sensor data into meaningful insights for proactive maintenance.
Backgrounder: Magnetic Flux Density (MFD) and Steel Pipelines
Steel pipelines are often magnetized due to factors like industrial processes, transport, and the Earth’s magnetic field. This magnetization has two primary components:
- Remanent magnetization, which is semi-permanent and caused by industrial handling
- Induced magnetization, which results from exposure to the Earth’s magnetic field
Magnetic Flux Density (MFD) measurements can be used to determine the level of magnetization. MFD measures the strength and direction of a magnetic field at a given point, which is equivalent to the density of magnetic field lines passing through a specific area.
The MFD is proportional to the volume of metal, which means it can be used to assess the volume of pipeline metal at a given location. For instance, areas with fittings will typically have higher MFD readings due to the additional metal, whereas areas with wall thinning will show lower MFD readings due to the reduced metal volume.
Although this method has a lower resolution compared to conventional Magnetic Flux Leakage (MFL) measurements, the benefit of using MFD measurements is that the pipeline doesn’t have to be cleaned ahead of the inspection and that pipelines that can’t be inspected with conventional MFL tools can be inspected with MFD tools.

What else can INGU Pipers® do?
Leak Detection
Pipers® record all sounds while moving with the flow through the pipeline making them sensitive to even the smallest leaks.
Air/Gas Pocket Detection
Pipers® use an acoustic sensor to identify the unique data signatures of air/gas pockets within the pipeline.
Confirmation of Containment
Pipers® inspect the pipeline under operational conditions, making them an ideal tool to confirm containment without disrupting operations.
Deposit Inspection
Pipers® take 100 pressure measurements per second while moving through the pipeline allowing for accurate deposit localization.
Hydraulic Grade Line Inspection
Pipers® continuously measure the pressure providing a highly detailed method for determining the hydraulic grade line.
Magnetic Inspection
Pipers® serve as an in-between solution between hydrostatic testing and conventional in-line inspection tools (i.e. smart pigs), helping operators keep their pipelines safe.
Magnetic Feature Detection
Pipers® measure the magnetic flux density in a pipeline allowing for the localization of any metallic fittings and casings in a non-metallic pipeline.
Hot Tap Detection
Hot taps, particularly illegal ones, pose significant risks to pipeline integrity, safety, and operational efficiency.
Bend Detection
When combined with off-the-shelf cleaning pigs, Pipers® provide the bend angle, radius, and direction.
