Eddy Current Tube Testing Equipment

Eddy current testing ect as a technique for testing finds its roots in electromagnetism.

Eddy current tube testing equipment.

Eddy current testing equipment utilizes the frequency generator impedance bridge as well as a probe that houses one or more coils. 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 of heat exchanger tubes means detecting more circumferential and axial cracks including wall thinness. Get eddy current equipment for tube bar and wire from bkn leading ect testing equipment manufacturer.

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. Our high performance equipment and solutions includes ge s portable mentor em the nortec 500 series and the nexxis. Eddy currents were first observed by françois arago in 1824 but french physicist léon foucault is credited with discovering them in 1855. The first commercial use of this type of testing was introduced in 1930 and was called the model e probolog.

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. Two coupling paths exist between the transmitters and receivers. The direct path inside the tube is rapidly attenuated by circumferential eddy currents induced in the tube s wall. High quality eddy current testing solutions for complete inspections.

Intertek s non destructive testing inspectors are pcn asnt and nas410 level ii or iii qualified in eddy. The product is passed through or adjacent to an electrical test coil which has been excited by an alternating current. Eddy current tube testing. We have the most extensive experience and we develop the highest quality ect inspection products.

A benefit of eddy current testing is that detection of defects is instant and can be reported immediately to site or operation managers. The theory was first introduced in 1879. Tube testing technologies products selectedtext inspection instruments prod name. 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.

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. The indirect coupling path originates in the transmitter s magnetic field that diffuses radially outward through the wall. Encircling and sector eddy current coil tests perform in this manner.
