Eddy current testing, often used to inspect tubes, involves passing an alternating current through a coil to generate changing magnetic fields. These fields induce eddy currents in conductive materials like metal tubes. Here’s how it applies to tube inspection:
Eddy current testing, often used to inspect tubes, involves passing an alternating current through a coil to generate changing magnetic fields. These fields induce eddy currents in conductive materials like metal tubes. Here’s how it applies to tube inspection:
Eddy currents create their own magnetic fields, which interact with the primary magnetic field generated by the coil. Any discontinuities or changes in the material (such as cracks, corrosion, or changes in thickness) alter the eddy currents' flow and affect the impedance of the coil.
In the context of tubes, eddy current testing is commonly used to inspect heat exchanger tubes, boiler tubes, condenser tubes, and other critical components in various industries including power generation, oil and gas, aerospace.
