Eddy Current Tube Testing Equipment

Ect began largely as a result of the english scientist michael faraday s discovery of electromagnetic induction in 1831.

Eddy current tube testing equipment.

Tube testing technologies products selectedtext inspection instruments prod name. Eddy current testing of heat exchanger tubes means detecting more circumferential and axial cracks including wall thinness. Eddy current testing equipment utilizes the frequency generator impedance bridge as well as a probe that houses one or more coils. 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 current testing of tubes is highly specialised requiring expertise and specialist equipment. Eddy currents were first observed by françois arago in 1824 but french physicist léon foucault is credited with discovering them in 1855. Two coupling paths exist between the transmitters and receivers. Eddy current testing ect as a technique for testing finds its roots in electromagnetism.

The indirect coupling path originates in the transmitter s magnetic field that diffuses radially outward through the wall. 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. Applicable to surface defect detection of non ferrous metals stainless steel tubes they can be widely used for on line or off line non destructive testing of raw materials for various industry. 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.

Get eddy current equipment for tube bar and wire from bkn leading ect testing equipment manufacturer. Zetec is the industry leader for cost effective eddy current testing ect in complex applications. The direct path inside the tube is rapidly attenuated by circumferential eddy currents induced in the tube s wall. A benefit of eddy current testing is that detection of defects is instant and can be reported immediately to site or operation managers.

We have the most extensive experience and we develop the highest quality ect inspection products. Eddy current tube testing. The theory was first introduced in 1879. 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.

High quality eddy current testing solutions for complete inspections. Encircling and sector eddy current coil tests perform in this manner. Intertek s non destructive testing inspectors are pcn asnt and nas410 level ii or iii qualified in eddy.
