HEF-17B Pulse Eddy Current in-service inspection metal pipe wall thickness outside the cladding layer Detection Instrument
1 Brief introduction
The equipment can be used for in-service inspection of metal pipe wall thickness outside the cladding layer, instead of traditional sinusoidal current incentives to pulse current, pulse magnetic field outside the conductor, the conductor in the pulsed eddy current sensor, by measuring the attenuation process of pulsed eddy current electromagnetic field, to assess the degree of corrosion of pipe wall thickness.Compared with the traditional wall thickness detection method: without burnish, without coupling, equipment continuous scan in service, can significantly improve the detection efficiency.
Compared with conventional pulsed eddy current testing technology, precision scanning features: less interference from environmental factors, high detection efficiency, higher resolution (can find small corrosion, the missed detection rate is extremely low), suitable for corrosion detection of high-risk parts without coating layer (without or after removal) or thin coating layer (less than 300mm anticorrosive coating layer, etc.),for example: production plant process pipeline, water wall, furnace tube, small joint pipe, elbow, tee, etc.

3 Functional features
l ★There are shortcut keys and LCD screen on the probe, which can display the working status and detection data in real time, and the work efficiency is greatly improved without frequent operation of the host during the detection process.
l ★The probe adopts electronic focusing technology, which has higher spatial resolution, greater recognition, and stronger anti-interference ability for local corrosion defects.
l Not sensitive to the shape of defects, it can detect the wall thickness corrosion or other thickness reduction defects of metal members "with cover layer (insulation layer, cooling layer, protective layer, etc.)".
l Inspections can be done when the equipment is running (High temperature, low temperature, materials in the equipment etc.).
l Materials that was detected: Detection of remaining wall thicknesses ferromagnetic metal material such as carbon steel, low alloy steel.
l ★It can also detect the remaining wall thicknesses of stainless steel, aluminum alloy and other non-ferromagnetic metal materials.
l Tube plate shape: Plate, straight pipe, elbow,tank.
l Cladding layer materials: non-conductive, non-magnetic materials( asbestos, foam etc.), metal mesh, iron sheet, aluminum sheet and other metal protective layer.
l AC/DC hybrid power supply, built-in rechargeable lithium batterycontinually working more than 4 hours.
l Fully sealed IP64 anti-dust and anti-splash design, silicone sheath anti-drop and anti-vibration design, more suitable for harsh working conditions.
