Evaluation of Acoustic Emission Inspection of Oil Tank Floor via Tank Bottom Plates Thickness Measurement
This paper deals with an inspection of defects including corrosion and leakage by Acoustic Emission (AE) in an oil tank floor. In contrast to intrusive methods such as magnetic flux leakage, eddy current or ultrasonic, there is no need to emptying and entering the tank in AE method in order to inspection. In this research AE investigation and AE source location is presented in detail. The resul...
متن کاملInspection of Power Plant Headers Utilizing Acoustic Emission Monitoring
Fossil power plant high energy, high temperature steam headers have been found to be susceptible to thermal fatigue assisted creep degradation. These mechanisms initiate and grow cracks in chrome molybdenum headers, from the bore hole edges and stub tube-to-header welds. Linking up of multiple cracks can lead to explosive expulsion of tubes and severe shorting of the header life. In order to ex...
متن کاملAcoustic Inspection of Coated Steel Bar in Reinforced Concrete Structure
Bridges with reinforeerneut corrosion problems are now under careful inspection in Taiwan. Costly maintenance programs are underway and raising S"erious safety concem. There are various engineering solutions to salt-induced corrosion. Among them epoxycoated reinforcing bars, commonly referred to as rebar, are frequently used in marine environment and other areas due to its durability, reasonabl...
متن کاملElectromagnetic Acoustic Transducers for Robotic Nondestructive Inspection in Harsh Environments
Elevated temperature, gamma radiation, and geometric constraints inside dry storage casks for spent nuclear fuel represent a harsh environment for nondestructive inspection of the cask and require that the inspection be conducted with a robotic system. Electromagnetic acoustic transducers (EMATs) using non-contact ultrasonic transduction based on the Lorentz force to excite/receive ultrasonic w...
