Why Does Our Company Need To Do Eddy Current (ET) Testing On Tube And Shell Heat Exchangers?
Eddy current testing detects flaws in conductive materials using electromagnetic induction. By placing a coil carrying current next to the part needing inspection and changing the magnetic field using alternating current, the process creates eddy currents. Reading changes in the phase and magnitude of these currents can detect flaws in the components being tested.
“Eddy current testing can find cracks, pitting, corrosion, and thinning on tube and shell heat exchangers so, in order for your equipment to be efficient, you want to make sure there’s no internal damage,” said Jim Hallberg, General Manager of Paragon NDT, LLC, a subsidiary of PROtect.
According to Hallberg, eddy current testing is driven by the American Petroleum Institute (API) 510 internal inspection regulations of pressure vessels. The code was first created in 1958 but has evolved to better encompass improvements in technology and methodology. API designed the code with eddy current testing to ensure pressure vessels continue to work at peak performance.
“When we do eddy current testing inspection, we can find all the flaws and make sure equipment runs efficiently,” said Hallberg.
