Electromagnetic ultrasonic automatic testing equipment for steel plate
This equipment mainly used for high temperature, hydrophobus and low temperature environment. Such as normal steel, high-quality-steel, alloy steel, spring steel, stainless steel, tool steel, heat resistant steel, bearing steel, silicon steel and industrial pure iron sheet etc.
◆ Comb scanning or pendulum scanning to detect flat-bottomed holes or grooves
◆ The edge of the plate sheet adopts edge detection tracking method to detect flat-bottomed holes or grooves
◆ API SPEC 5L 《Steel pipe specification of pipe line》(44 Edition)
◆ GB/T9711.1-1997《Technical delivery conditions of steel pipes for petroleum and natural gas industries, part 1》
◆ GB/T9711.2-1999《Technical delivery conditions for steel pipes for petroleum and natural gas industries, part 2》

◆ ISO3183-3《America pipe line specification》
◆ DEP126.96.36.199 （2011）《Pipe specification of shell pipe line》
◆ JB/T4730.3-2005《Non-destructive testing of pressure vessels – ultrasonic testing》
◆ RCC-M、ASME-Ⅲ、Ⅴ and Shell and relevant products’ technical supplementary agreement for ultrasonic flaw detection requirements
The form of mechanical structure
◆ Gantry beam type (traditional type)
◆ It can also be customized according to the specific requirements of users
1. Full information records to record waveforms, real 1:1 restoration of defect position and length.
2. Realize the function of layered thickness measurement, record at the same time, and automatically calibrate the sensitivity.
3. Automatically set the gate position and range according to the thickness of the input plate.
4. The automatic detection results can be stored and printed, and the detection records (detection curves and related data) can be stored on the storage medium. The industrial computer could permanently store the continuous detection records. When the test results need to be modified, need password authorization.
5. Adopt the gate tracing mode, which can effectively solve the false alarm caused by the shaking of the plate.
No water required for coupling
Electromagnetic ultrasonic detection technology does not require water for coupling, which is convenient and environmentally friendly, especially suitable for use in cold winter.
The waveform is stable and basically will not change with the change of probe state, which is suitable for industrial on-line automatic operation.
High temperature resistance
Can be used for flaw detection of high temperature plates.
Up to 800 channels of array scanning, modular structure of the instrument, easy to upgrade.
Easy to maintain
The system has self-check function, which is convenient for multi module maintenance of large system.
The signal exchange mechanism based on the network topology structure, which provides more stable transmission and more convenient maintenance.
