Acoustic Emission Test of Changlongshan Pumped Storage Power Station Steel Bifurcation Pipe
Standard & Quality Control Research Institute Ministry of Water Resources.P.R.C, Hangzhou 310012, China
The maximum test load of Changlongshan pumped storage power station steel bifurcation pipe is 10MPa. To ensure the safety of the water pressure test, acoustic emission is used to monitor the main welds of the crescent rib steel bifurcation and main cone. Taking NO.3 pipe’s data as an example, acoustic emission source location system was used to find the possible position of harmful defects, through the activity and intensity of the acoustic emission sources to confirm the defect significance. After analysis, the acoustic emission integrated level of the steel bifurcation pipe is in level II, the pipe’s data comply with the design requirements.
