Magnetic Leakage Detector Embarks on a New Journey of Non Destructive Testing

In the grand pattern of industrial production and infrastructure construction, ferromagnetic components such as pipelines

 and storage tanks are like arteries that maintain the operation of life, undertaking the important task of transporting 

key media such as oil and gas, chemical raw materials, etc. Its structural integrity is directly related to production safety, 

stable energy supply, and even ecological environment security. 

However, during long-term service, problems such as corrosion, fatigue damage, and natural aging are difficult to avoid, 

which may lead to serious accidents such as leaks and explosions. How to achieve precise identification and evaluation 

of defects without damaging components has become an urgent technical challenge in the industrial field. Magnetic flux 

leakage testing technology, as one of the core technologies in the field of non-destructive testing, has become a key 

path to solving this challenge due to its advantages of non-contact, high efficiency, and high sensitivity. The magnetic 

flux leakage detector developed by Yaisu Intel-tech is an outstanding representative on this technological path.

Magnetic leakage detection is based on the magnetic properties of ferromagnetic materials. When the tested component 

reaches magnetic saturation under strong magnetic field, a closed magnetic circuit is formed inside. Once there are 

surface or near surface defects such as cracks, corrosion pits, etc., the magnetic field lines will be distorted, and some of 

the magnetic field will leak into the air, forming a detectable leakage magnetic field. By using high-precision magnetic 

sensors to collect these weak signals and combining them with data processing algorithms for analysis, accurate 

determination of defect location, size, and shape can be achieved, completing a "non-invasive physical examination" 

of the equipment's health status.

Compared to traditional detection methods, magnetic flux leakage detection has significant advantages: it does not 

require coupling media, supports non-contact detection, and avoids damage to the inspected surface; Fast detection 

speed, suitable for various online and offline working conditions, greatly improving work efficiency; Highly sensitive to 

surface and subsurface defects of ferromagnetic materials, even micrometer level damage can be effectively identified. 

Therefore, this technology has been widely applied in the regular inspection and status assessment of key facilities 

such as oil and gas long-distance pipelines, submarine pipelines, tank bottom plates, and rail transit rails, and has 

become an important component of the modern industrial safety guarantee system.

Yaisu Intel-tech is a high-tech enterprise specializing in pipeline magnetic leakage internal detection and magnetic 

adsorption wall climbing robot automation technology, always adhering to the mission of "safeguarding industrial 

safety and promoting industry progress". The company gathers professionals from top scientific research institutions 

such as the Chinese Academy of Sciences, Zhejiang Tsinghua Flexible Electronic Technology Research Institute, Hebei 

University of Technology, and has accumulated profound experience in the research and development of magnetic 

flux leakage testing technology and engineering applications, forming a complete technical closed-loop from theoretical 

research to product implementation.

Thanks to its outstanding performance, Yaisu Intel-tech's magnetic flux leakage detector has been successfully applied

 in multiple key industrial scenarios. In the inspection of long-distance oil and gas pipelines, the equipment can
