TDW introduced high resolution MAGPIE® deformation tools into the market in the summer of 2003. The new generation of tools has raised industry standards with unprecedented accuracy, resolution and reliability. Minimal changes in the internal wall topography, such as seamless pipe variations, are often clearly visible. Misaligned coupon welds, flanges and valves are detected and measured.

Dents measured by new MAGPIE high resolution deformation tools provide a level of accuracy that rivals hand measurements taken during expensive excavations. Data is easily and conveniently displayed using intuitive MAGPIE PIGTRAP™ software.

Features include:

• One sensor every inch on internal circumference for amazing detail.
• INS data details bends and clock position.
• Variations less than 0.020" (0.5mm) are visible with the smaller tools.
• Like all of our specifications, the 1% accuracy is conservative compared to what the tool can actually do.
• Based on the same system as our MFL tools for proven reliability and efficiency.
• Quick scan software allows for MFL tool clearance go/nogo calls within hours.
• Can be configured with our MFL tools for one pass MFL/deformation surveys.

A barred Tee on a 10" pipe. With tight arm spacing on the MAGPIE tool you can easily count the bars and detect detached or missing bars.

The MAGPIE deformation tool family will cover a range of sizes from 4” to 42”. All tools feature INS sensors, direct on-the-wall measuring arms, high resolution odometers and a highly reliable design that minimizes exposed components. Tools can be easily started and stopped using a Palm™ PDA. The system is supported with GPS and Bluetooth™ Above Ground Markers, making the entire inspection process simpler, more reliable and less expensive for our customers. Deformation tools use the same highly acclaimed PIGTRAP software and high reliability internal electronics that our MFL tools use.
