Now: EMAT Crack ILI of Difficult-to-Inspect Small Diameter Pipelines

Our short-body, low drag EMAT Crack ILI tools provide superior navigability. They are ideal for low-pressure difficult-to-inspect, or unpiggable pipelines.  The system’s unidirectional, mode controlled guided waves resolve signal congestion issues allowing for improved flaw detection and sizing accuracy in small-diameters.

Applications: (format to style rules)

  • Liquid and Gas Pipelines
  • Gathering Pipelines
  • Transmission Pipelines
  • Distribution Mains
  • Cased Crossings
  • Process Pipelines

Specifications:

  • Inspects 8”, 10” and 12” diameter pipelines
  • Will inspect 14”, 16” and 20” diameter pipelines in 2022
  • Free swimming at differential pressure as low as 50 psi
  • Operable pressure ranges from 200 to 2200 psi
  • Navigates back-to-back bends with >90° short radius turns
  • Tool tested through plane and full-bore restrictions
  • Low drag for smooth transitions through bends to minimize pressure spikes
  • Short body 8” tool ~ 6- foot in length with only 2 sensor modules + 3 battery/encoder modules
  • Run length adjustable with addition of battery modules
  • Accommodates single entry/exit line stoppage, plugged valves

Feature Capabilities:

  • Improved Circumferential Coverage: “Zero” blind spots
  • Multi-Crack Detection: Axial including cracks in dents
  • Agile acoustic operating mode for different pipe wall thicknesses
  • Higher operating power for lossy coatings
  • Unidirectional guided waves process clearer signals and readings
