BKNET-999H Copper Tube Eddy Current Flaw Detector brief 


Eddy current testing is a non-destructive testing technique in which an alternating current electromagnetic coil induces eddy currents on the surface of a metal member. It is suitable for the detection of defects in conductive materials, including ferromagnetic and non-ferromagnetic metal materials. 


Due to the eddy current flaw detection, the coil is not required to be in close contact with the member at the time of detection, and the chelating agent is not required to be filled between the coil and the member, and the inspection automation is easily realized. 


However, eddy current testing is only applicable to conductive materials, and can only detect defects on the surface or near-surface layer, and is inconvenient for components with complicated shapes. In thermal power plants, it is mainly used to detect condenser tubes, steam turbine blades, turbine rotor intermediate holes and welds.
