The L-shaped pipes are widely used in the petro-chemical plants and vulnerable to the corrosion in the bending region because of the flow direction change and high temperature environment of over 600 ℃. Therefore, it is necessary that the corrosion status of the pipes should be monitored for safety purpose.
In this study we have tried to get the high resolution thickness information of the L-shaped pipes with EMAT(Electro-Magnetic Acoustic Transducer) sensors.
The thickness information can be obtained by getting delay time between two neighboring tone burst signals. The EMAT electronics is poor in the noise property, which gives low signal to noise ratio. So, we have applied the appro ... 전체 초록 보기
