Pipe Explorer Sensor Specifications
Specifications of Magnetic Flux Leakage Sensors
| General Metal Loss Sizing Specification | Nominal Pipe | Case Pipe |
|---|---|---|
| Depth at POD = 90% | 0.10t | 0.20t |
| Depth Accuracy (80% confidence) | ± 0.10t | ± 0.20t |
| Width Accuracy (80% confidence) | ± 0.75 inches ± 20 mm | ± 1 inches ± 25 mm |
| Length Accuracy (80% confidence) | ± 0.5 inches ± 12 mm | ± 0.75 inches ± 20 mm |
- t = wall thickness
- Detection threshold and sizing accuracy in bends are unspecified
- Detection threshold increases to 0.15t and depth sizing accuracy degrades to ±0.15t in seamless pipe
- Depth sizing accuracy degrades to ±0.20t near girth welds or in heat affected zones
