Eddy Current Inspection of Heat Exchanger Tubes

ec-works performs eddy current inspections of heat exchanger tubing on a wide variety of systems including condensers, reactors, cooling devices, heat exchangers and air coolers with a diversity of common tube dimensions, shapes and materials as titanium, brass, various copper-nickel-grades, stainless steels, duplex-grades etc.

We offer special eddy current inspections for ferromagnetic tube materials with two eddy current technologies, PSEC and RFEC. The Partial Saturated Eddy Current inspection method is useful to detect and evaluate small volume defects like pitting corrosion. PSEC is the only inductive method to inspect finned tubes as common in air cooler systems and is truly efficient when wanting to detect inner and outer defects. Interpreting PSCE eddy current signals is linked with a great amount of knowledge, skill and experience - a performance which our trained operators deliver reliably.

The Remote Field Eddy Current method is a common method performed on ferromagnetic tubes. RFEC is an accurate and precise evaluation of wall thinning as known from erosive defects.

ec-works combines these inspection technologies for its C-Steel-tubing inspections. PSECT is the standard method used for ferromagnetic tubes and in cases where big volume shallow shaped defects are to be expected, RFEC will be used additionally.

ec-works is able to perform an eddy current tube inspection with an automatic signal evaluation tool to support our operators in the process of analyzing signals. Our modern technology enhances result detection and precision - an additional guarant for satisfactory quality.

ec-works has developed several rotating tools to increase the sensitivity of the eddy current tube inspection. E.g. applications for the regularly untested tube sheet area are on stock. We've also designed and manufactured probe systems developed to detect very small volume defects like needle-shaped holes causing steam erostion in titanium tubes located in condenser systems. Our company is highly dedicated towards working on the continual development and improvement of our profession.
