COBE has developed a principle of new diagnostic methods (in the 21st century the most important detection method) metal magnetic memory. COBE-8MM is the fruit of many years of industrial and laboratory studies based on the original COBEP0201. This testing principle is metal magnetic memory effect caused by the stress concentration of the overload part of workpiece. And this method is of fast detecting and there’s no requirement of metal surface clearness. Via detecting the potential flaw parts of the stress concentration area, we can ensure early diagnosis and warning for more efficient and safe manufacturing.
1.Early warning of the mechanical stress concentration area which is the main source of damage
2.Detecting the exact flaw of stress concentration areas and evaluate the degree of danger 。
3. Via the metal structure to determine the position, size and development direction of the potential cracks.
4.Evaluate the practical life of the equipments
Especially applicable to nuclear energy, electrical energy, petroleum, aerospace & aviation and other department on the flaw or stress concentration area evaluation of on-service metal parts, various Ferromagnetic pipes, boiler, pressure vessels and oil reservoirs to achieve safer and more reliable product usage.
