Gas Magnetic Flux Leakage (GMFL)

gas-magnetic-flux-leakage

Detection Capabilities

Metal Loss Anomalies
  • General Corrosion
  • Pitting Corrosion
  • Girth Weld Metal Loss
Construction Anomalies
  • Gouges and Grinding
  • Close Metal Objects

Designed specifically for natural gas pipelines, gas magnetic flux leakage (GMFL) technology detects and sizes volumetric metal loss and internal versus external discrimination without the risk of speed excursions that can affect data accuracy.

Key Features

  • GMFL tool design enables consistent drag to improve tool velocity profiles
  • Smoothly negotiates reductions in pipeline internal diameter
  • Detects and reports volumetric metal loss at 10 percent wall loss or greater
  • Accuracy of +/- 10% wall thickness for pitting and general corrosion

Sizes

  • 8-inch through 48-inch
