Tubing repair is an important measure to reduce the comprehensive cost of production in oil production plants to improve the quality of repairing tubing. It can ensure the quality of oil and water wells to prolong the inspection cycle, reduce the rework of operations and reduce operating costs.  

As an important process in the tubing repair test line, the flaw detection can accurately and effectively detect the defects in the manufacture and use of the inner and outer wall and the pipe body of the oil pipe to ensure the repair quality of the oil pipe.

Fundamental

When the detected tubing is saturated and magnetized, the magnetic field lines are distorted by the magnetic lines of force at the defect blocking defect, and a part of the magnetic lines leak out of the inner surface of the tube rod to form a leakage magnetic field, and the electromagnetic detecting method for detecting the leakage magnetic field by the detecting element is detected.  Magnetic flux leakage inspection.  

The mfl tube picked up by the probe from the defect is amplified and converted into a digital signal, and then visually reflected by the flaw detector to the display to display the defect signal from the flaw detector, and directly determine the defect type and size of the detected tube rod.

¢73 and ¢89mm tubing eccentric wear and corrosion pits are detected, automatic detection, automatic alarm, automatic identification, automatic alarm.

Our company's new MFI mfl tube inspection machine has high sensitivity to very small defects. It can effectively detect defects such as corrosion pits, eccentric wear on the inner wall of the tubing, thinning of tubing wall, etc.

Moreover, the testing speed is fast and pollution-free, and the detection is fully automated. The computer display screen is used to display the detection curve, automatic alarm, marking (defect of steel pipe), grading of tubing (grade I, II and scrap).

Technical Characteristics of MFL101 mfl tank floor scanner

Unique full modular structure, from the main body of the computer mechanism the handle of MFL101 Tank Floor MFL Scanner can be quickly folded, disassembled. It is easy to transport and access manholes. With humanized operation design, the height of armrest and adjustable angle, suitable for different operators. Precise signal conditioning circuit. The four-layer PCB with mixed power excellent performance. data word signal processing system, supercomputing power, advanced evaluation algorithm.

High-performance touch industrial tablet. The operation is very convenient does not require a keyboard and mouse. Unique probe design. It can pick up the magnetic flux leakage signal to overcome the unwanted signal caused by the eddy current effect. The number of physical channels is up to 32. High-performance lithium battery pack, which is at least 50% lighter than the equivalent capacity lead-acid battery Software design that can be operated efficiently.

All scan parameter settings graphical, intuitive, and easy to use, dramatically increasing the speed of operation and avoiding errors. The magnetization is quickly adjustable. By adjusting the ground clearance the magnetic pole, the magnetization of the detection target plate can be quickly changed to meet the requirements of detecting the thickness and minimize the gravity of the instrument and the bottom plate. This design allows the instrument to adapt to a wide range of floor thicknesses and reduce operator effort, increasing battery life.

Different degrees of corrosion are represented by non-color blocks. Online analysis of corrosion degree and position, position coordinates can be displayed in a table or on a scan.

The main detection principle of the MFI magnetic flux leakage pipeline inspection method is that the workpiece is magnetized (close to saturation) to have a certain magnetic flux density to generate a leakage magnetic field at the discontinuity, and the magnetic field sensor sends the output signal to the operational amplifier.

Due to the magnetic saturation state, the workpiece has a relatively high magnetic field strength and magnetic field density, and the magnetic lines of force are not limited so that the surface of the workpiece has a large magnetic leakage, which is favorable for on-site detection.

The magnetic sensitive sensor scans along the surface of the magnetized ferromagnetic material, pick up the defect leakage magnetic field and forms a defect electrical signal to achieve the purpose of finding the defect position and parameters.

Non-destructive mfl pipeline inspection technology is widely used in the detection of metal materials and the evaluation of related products due to its fast detection speed, high reliability and low surface cleanliness. Different from magnetic particle detection and detection, the signal in magnetic flux leakage detection is not displayed by magnetic powder, and it has no pollution to the environment: due to various sensitive components (such as Hall element and coil method), the detection result is directly output by electric signal, which is easy to connect with computer to realize digital Processing, so the detection results can be stored and reproduced, facilitating the analysis of the detection signal and the trend analysis of the detection results.
