REMOTE FIELD EDDY CURRENT BASED SYSTEM AND METHOD FOR CORROSION INSPECTION - A simplified explanation of the abstract

This abstract first appeared for US patent application 18376142 titled 'REMOTE FIELD EDDY CURRENT BASED SYSTEM AND METHOD FOR CORROSION INSPECTION

Simplified Explanation

The patent application describes a remote field eddy current (RFEC) system for detecting the azimuth location of a defect in a pipe using magnetic fields and a fluxgate magnetometer.

• The system includes a holder that flows through the pipe, a magnetic field generator to create a magnetic field, a fluxgate magnetometer to measure the resulting magnetic field interacting with the defect, and a controller to determine the azimuth of the defect and its extent based on the measured field.

Potential Applications

The technology can be used in various industries such as oil and gas, water distribution, and manufacturing for non-destructive testing of pipes to detect defects accurately.

Problems Solved

1. Accurately detecting the azimuth location of defects in pipes. 2. Providing a non-destructive testing method for pipes to prevent potential leaks or failures.

Benefits

1. Early detection of defects in pipes. 2. Preventing costly repairs or replacements. 3. Improving overall pipeline safety and reliability.

Potential Commercial Applications

"Remote Field Eddy Current (RFEC) System for Pipe Defect Detection" can be used in industries such as oil and gas, water distribution, and manufacturing for regular inspection and maintenance of pipelines.

Possible Prior Art

One possible prior art is the use of traditional eddy current testing methods for detecting defects in pipes. However, the RFEC system described in the patent application offers improved accuracy and efficiency in detecting the azimuth location of defects.

How does the RFEC system handle different pipe materials and thicknesses?

The patent application does not provide specific details on how the RFEC system adapts to different pipe materials and thicknesses to ensure accurate defect detection.

What is the cost-effectiveness of implementing the RFEC system compared to traditional testing methods?

The patent application does not discuss the cost-effectiveness of using the RFEC system for pipe defect detection in comparison to traditional testing methods.

Original Abstract Submitted

A remote field eddy current, RFEC, system for detecting an azimuth location of a defect in a pipe includes a holder extending along a longitudinal axis X and shaped to flow through the pipe, a magnetic field generator located within the holder and configured to generate a first magnetic field B, a 3-axis fluxgate magnetometer located within the holder, at a given distance away from the transmitter, along the longitudinal axis X, wherein the fluxgate magnetometer is configured to measure a second magnetic field B, which is a result of the first magnetic field Binteracting with the defect in the pipe, and a controller located within the holder and configured to receive a value of the second magnetic field B and to determine an azimuth of the defect in the pipe by interpreting radial components of the measured field, and an extent of the defect based on the second magnetic field B.
