Product Description What is EMI non-destructive testing for drill pipes?Drill pipe EMI (Electromagnetic Inspection) non-destructive testing is a detection technology based on the principle of electromagnetic induction, specifically used to detect defects inside drill pipes, such as cracks, corrosion, wall thickness changes, etc. This detection method can accurately and quickly identify potential problems inside the drill pipe without compromising its performance, which is of great significance for ensuring the safety and efficiency of drilling operations.Working principleEMI non-destructive testing utilizes electromagnetic induction phenomenon to transmit electromagnetic waves to the surface of the drill pipe through specific probes. When electromagnetic waves encounter defects inside the drill pipe, they will reflect or scatter, and these changes will be captured and analyzed by detection instruments to deduce information such as the location and shape of the defects inside the drill pipe. This method has the advantages of easy operation, high detection efficiency, and high sensitivity.Application area BKN Drill pipe EMI non-destructive testing is widely used in fields such as petroleum drilling and geological exploration. In the process of oil drilling, drill pipe is one of the key equipment, and its quality and safety directly affect the success of drilling operations. By regularly conducting EMI non-destructive testing on drill pipes, potential defects can be detected and addressed in a timely manner, avoiding accidents such as breakage and leakage during use, and ensuring the safety and smooth progress of drilling operations.Detection ProcessThe general process of EMI non-destructive testing for drill pipes includes the following steps:1. Preparation: Carefully inspect the testing equipment to ensure that the probes, connecting wires, and other devices are intact and undamaged; At the same time, clean the drilling rod to remove surface dirt and rust.2. Drill rod fixation: Place the drill rod to be tested vertically and use a special fixture to fix it in place, ensuring that the distance between the drill rod and the probe is appropriate.3. Parameter setting: Set appropriate detection parameters based on the material, diameter, and other parameters of the drill rod to be tested, and perform calibration and debugging.4. Start detection: Start the detection equipment and move the probe along the axis direction of the drill rod for detection. During the detection process, it is necessary to record the probe position and signal response.5. Data analysis: Analyze and process the collected data, and make comprehensive judgments based on the historical data and actual situation of the drill pipe.6. Result output: Based on the analysis results, output corresponding inspection reports or diagrams to make reasonable evaluations and suggestions on the quality status of the drill pipe.PrecautionsWhen conducting EMI non-destructive testing on drill pipes, the following points should be noted:-Ensure sufficient contact between the probe and the surface of the drill rod to avoid missed or false detections.-Control the movement speed and direction of the probe to maintain relative stability and obtain accurate detection results.-Pay attention to the cleanliness of the drill pipe surface to avoid the influence of dirt and rust on the test results.-Regularly maintain and calibrate the testing equipment to ensure its stable and reliable performance.In summary, EMI non-destructive testing of drill pipes is an efficient and accurate technique for detecting internal defects in drill pipes, which is of great significance for ensuring the safety and efficiency of drilling operations. With the continuous advancement of technology and the expansion of application fields, EMI non-destructive testing of drill pipes will play an important role in more fields.Magnetic flux leakage test refers to the formation of a leakage magnetic field on the surface of a test piece after it is magnetized due to defects on the surface or near-surface of the test piece. People can detect defects by detecting the change of leakage magnetic field with MFL testing equipment.Briefly describe the magnetization of ferromagnetic components. In the magnetic non-destructive testing, magnetization is the first step to realize the detection, which determines whether the leakage magnetic field signal can be generated, and also affects the performance characteristics of the detection signal and the structural characteristics of the detection device. Like magnetic particle inspection, magnetization is achieved by a magnetizer, including both a magnetic source and a magnetic circuit.The magnetic source and the magnetic circuit change depending on the structure of the member to be tested.What kind of magnetization can be divided into several categories? The magnetization methods can be generally divided into five categories, namely, alternating current magnetization mode, direct current magnetization mode, permanent magnet magnetization mode, composite magnetization mode, and integrated magnetization method.What are the characteristics of magnetic flux leakage detection technology?Because leakage magnetic field detection uses magnetic sensors to detect defects, compared with magnetic powder, penetration and other methods, it has the following advantages:1. It is easy to realize automation. The computer judges the presence or absence of defects based on the detected signals.2. The fundamentally high detection reliability can solve the influence of human factors in the magnetic powder and osmosis method, and has high detection reliability. 3. can achieve preliminary quantification of defects. In the range of wall thicknesses up to 30 mm, the inner and outer wall defects can be detected simultaneously. In the detection of the pipeline, 5 high-efficiency, pollution-free automated inspection can achieve high detection efficiency.BKN's portable magnetic flux leakage testing equipment are capable of detecting workpieces efficiently and accurately.As an mfl testing equipment manufacturer and supplier, we have been committed to developing and manufacturing high-quality and high-performance NDT equipment to provide customers with the best quality service.We are one of the professional non destructive testing equipment suppliers,we provide magnetic flux leakage equipment,mfl equipment,mfl ndt,magnetic flux detector and ndt testing,if you don't know what is flux leakage,we will tell you.
