X-ray Digital Imaging Inspection of In-service Governor Oil Supply Pipeline
Be aimed at the two failure forms of the in-service oil supply pipeline of the governor of pumped storage power station,taking into account the high density of oil medium and the blackness of film photography technology can not meet the standard requirements,a X-ray digital imaging detection method was proposed to detect the defects of in-service oil supply pipeline weld of the governor in the manufacturing and service stage.This experiment used the OR1417 DR imaging system dual wall single shadow radiographic technology to conduct detection on the welds of in-service governor oil supply pipelines.The detection results show that the presence of oil medium can reduce the weld imaging quality,but the X-ray digital imaging detection method can find the defect of weld root concave defects,which can satisfy the detection requirements.
