| Net Improvement | This project adapted JENTEK's Meandering Winding Magnetometer (MWM) Array and Magnetoresistive (MR) MWM Array for the detection and characterization of corrosion and mechanical damage through coatings. The project provided a foundation for the development of the enhanced characterization of mechanical damage, corrosion, SCC, and welding defects being developed under related DOT funding (Project 354, Contract DTPH56-10-T-000009). It has also led to commercially-funded demonstrations for the characterization of internal and external corrosion through insulation and weather protection. This capability is currently being commercialized by JENTEK Sensors for a 2013 product launch. |

Main Objective
JENTEK will deliver new capability for inspection from outside pipelines, without coating/insulation removal. The goal is reliable/rapid imaging of external/internal corrosion, mechanical damage, and SCC. With matching funds from Chevron, we will first adapt Meandering Winding Magnetometer (MWM)-Array technology for external damage, using high frequency methods. This includes integrated field demonstrations within twenty-four months. Solution for internal corrosion will transition later, using lower frequency methods.
Public Abstract
This project will develop improved nondestructive evaluation (NDE) methods for detection and characterization of damage in pipelines, from the outside, through coatings and insulation. The damage conditions of interest include internal and external corrosion, mechanical damage, and stress corrosion cracking (SCC). This will be accomplished by adapting JENTEK Sensors Inc.'s proven MWM-Array technology and developing a field deployable MWM-Array tool. The magnetic field-based sensor arrays and JENTEK model-based inverse methods are used to determine electromagnetic and geometric properties of the pipeline material, which are then related to specific damage conditions of interest. This technology has been successfully applied in the aerospace and manufacturing industries and provides substantially improved performance for imaging surface and buried damage through coatings and for curved surfaces compared to conventional NDE methods. The team for this program is JENTEK, Chevron, and Applus/RTD. This is a consolidated program with Project No 236.
