ECT Eddy current testing is a non-contact testing method, which mainly uses the electromagnetic field and electromagnetic induction between metals to detect. It is one of the NDT non-destructive testing methods in the industry.
We can use different coils according to the shape of the specimen and the purpose of detection. There are usually three types of coils: through a coil, probe coil and insert coil. It is mainly used for the rapid detection of metal pipes, rods and wires on production lines, and for the detection of large quantities of parts such as bearing steel balls, valves, etc.
1) The detection sensitivity of the surface of the conductive material and the near surface defects is high;
2) A wide range of applications can be monitored for various physical and technological factors affecting eddy current testing;
3) It is easy to realize high-speed, high-efficiency and automatic detection of tubes, rods and wires without using a coupling agent;
4) Under certain conditions, it can reflect information about the crack depth;
5) Monitoring can be carried out in the case where other detection methods such as high temperature, thin-walled tubes, thin wires, and inner surface of the parts are not applicable.
Eddy current testing of tubes, bars and wires including BKNET-999/H Copper Tube Eddy Current Flaw Detector, GSET-551steel wire eddy current testing, BKNET-101 Automatic Eddy Current Flaw Detector, Rod Tube Rotary Eddy Current Flaw Detector ET-R-15/40/65/90, BKNET-01\02 Welded Pipe Eddy Current Flaw Detector, LGET-553 Aluminum Tube Eddy Current Flaw Detector.
These equipments are mainly applicable to the surface defect detection of ferromagnetic non-ferrous metals, austenite, stainless steel tubes, rods and discs. It can be widely used for on-line or off-line NDT non-destructive testing of raw materials in energy, petrochemical, bearing, automobile, transom manufacturing, household appliances and other industries, such as bearings, raw materials of high strength bolts, copper, aluminum tubes of various refrigeration equipment, condenser tubes of evaporators, etc. This system is the necessary testing equipment for pipe and bar and wire production and application factory. This system adopts rotating balance point probe, resolver signal coupling, synchronously adjusting double detection probe, and the detection method of workpiece passing straight line. It has the characteristics of stable and reliable performance, high detection sensitivity, fast detection speed, no need for magnetizing and demagnetizing devices, and is sensitive to defect detection of pipe, bar and wire. It can make 100% NDT non-destructive detection of raw material surface. The equipment has the functions of defect alarm, automatic feeding and unloading and automatic sorting to achieve the detection automation. It provides an effective detection means for mass production of application pipes, rods and wires in factories and enterprises to ensure quality.
