Eddy Current Tube Testing Equipment

Eddy current testing of tubes is highly specialised requiring expertise and specialist equipment.

Eddy current tube testing equipment.

The direct path inside the tube is rapidly attenuated by circumferential eddy currents induced in the tube s wall. The product is passed through or adjacent to an electrical test coil which has been excited by an alternating current. The theory was first introduced in 1879. Two coupling paths exist between the transmitters and receivers.

Our high performance equipment and solutions includes ge s portable mentor em the nortec 500 series and the nexxis. The first commercial use of this type of testing was introduced in 1930 and was called the model e probolog. The indirect coupling path originates in the transmitter s magnetic field that diffuses radially outward through the wall. A benefit of eddy current testing is that detection of defects is instant and can be reported immediately to site or operation managers.

Eddy current inspection is a widely accepted ndt method that uses electromagnetism for rapid easy and cost effective scanning of welded structures raw materials and finished products in order to detect surface and sub surface flaws. Eddy current testing ect as a technique for testing finds its roots in electromagnetism. We have the most extensive experience and we develop the highest quality ect inspection products. Eddy current testing equipment utilizes the frequency generator impedance bridge as well as a probe that houses one or more coils.

Eddy current tube testing. Eddy current array and other ultrasonic and electromagnetic equipment including instruments sensors software and robotic solutions to key industries such as aerospace energy mining power generation and transportation. Eddy currents were first observed by françois arago in 1824 but french physicist léon foucault is credited with discovering them in 1855. Get eddy current equipment for tube bar and wire from bkn leading ect testing equipment manufacturer.

High quality eddy current testing solutions for complete inspections. This induces a flow of eddy currents around the test material or in the case of a sector coil in the area under the coil. Tube testing technologies products selectedtext inspection instruments prod name. For the best heat exchanger testing users can choose between a multiplex simultaneous injection instrument or a tubing array instrument with probes featuring either bobbin or array compatibility or ideally both.

Zetec is the industry leader for cost effective eddy current testing ect in complex applications. Encircling and sector eddy current coil tests perform in this manner. Ect began largely as a result of the english scientist michael faraday s discovery of electromagnetic induction in 1831.
