MS5800E – EDDY CURRENT TESTING (E) – REMOTE FIELD TESTING (R) Eddy current testing is a noncontact method used to inspect nonferromagnetic tubing. This technique is suitable for detecting and sizing metal discontinuities such as corrosion, erosion, wear, pitting, baffle cuts, wall loss, and cracks in nonferrous materials. Remote field testing (RFT) is being used to successfully inspect ferromagnetic tubing such as carbon steel or ferritic stainless steel. This technology offers good sensitivity when detecting and mea¬suring volumetric defects resulting from erosion, corrosion, wear, and baffle cuts. In addition to RFT, MS5800R also comes with Magnetic flux leakage (MFL), a fast inspection technique effective for aluminum-finned carbon steel tubes, because the magnetic field is almost completely unaffected by the presence of such fins.
