Remote Field Eddy Current Testing of Heat Exchanger Tubes

About Remote Field Eddy Current Testing of Heat Exchanger Tubes

REMOTE-FIELDEDDY CURRENT (RFEC) TESTING is a non destructive examination technique suitablefor the examination of conducting tubular goods using a probe from the inner surface. Because of the RFEC effect, the technique provides what is, in effect,a through-wall examination using only the interior probe. Although thetechnique is applicable to any conducting tubular material, it has been primarily applied to ferro magnetics because conventional eddy current testing techniquesare not suitable for detecting opposite-wall defects in such material unlessthe material can be magnetically saturated. In this case, corrosion/erosion wall thinning and pitting as well as cracking are the flaws of interest. One advantage of RFEC inspection for either ferromagnetic or non ferro magneticmaterial inspection is that the probe can be made more flexible than saturation eddy current or magnetic probes, thus facilitating the examination of tubes with bends or diameter changes. Another advantage of RFEC inspection is that itis approximately equal (within a factor of 2) in sensitivity to axially and circumferentially oriented flaws in ferromagnetic material. The major disadvantage of RFEC inspection is that, when applied to non ferromagnetic material, it isnot generally as sensitive or accurate as traditional eddy current testing techniques.

 

AtITE, we use Olympus MS 5800 for Remote Field Electromagnetic Testing in various components like Heat Exchangers, Reactors, Condensers, etc. All those tubeswhich are ferromagnetic in nature like made from the alloys of Steel, Nickel,etc. are tested. We have a formidable customer base for RFET like IOCL, NFL,JLSL,  etc. to name a few.

High-Resolution Flaw Detection

The remote field probe delivers outstanding sensitivity for distinguishing wall thickness changes as minute as 0.1 mm. Capable of reliably detecting through-wall flaws, pitting on both inner and outer diameters, and baffle cuts, this instrument ensures comprehensive integrity assessment for heat exchanger tubes. Each scan offers the clarity required for critical inspections, supporting robust maintenance decisions.


Compatible and User-Friendly Design

Designed for heat exchanger tubes with internal diameters between 12 mm and 50 mm, the RFET systems modular probe with interchangeable coil sets adapts quickly to various tube sizes. The instrument is portable, weighing just 1.5 kg, with a standard 15 m cable extendable to 30 m, enabling easy maneuverability in field environments. Accessories like adapters and calibration tubes enhance its usability.


Intelligent Data Analysis and Reporting

Advanced software supports real-time flaw imaging, automated and manual calibration, and detailed reporting. Store scan data internally or export via USB, Ethernet, or wireless connections. The system simplifies analysis, increases documentation efficiency, and provides alarms for immediate flaw notification, empowering teams to respond swiftly to inspection findings.
