Research on the Application of Piezoelectric Ultrasonic Corrosion Internal Inspection Technology in China-Myanmar Crude Oil Pipeline Project(Chinese Section)
Due to the frequent occurrence of geological disasters in the geographical environment of the China-Myanmar crude oil pipeline and the large fluctuation of the pipeline,several valve chambers along the pipeline are equipped with swing check valves.To solve the problem that the swing check valve structure causes damage to the inspection tool passing through,an pipeline internal corrosion detector with a self-protection function based on piezoelectric ultrasonic technology was improved and optimized.The computer-aided analysis method was used to simulate the process that the detector can pass through the swing check valve,and each protection function module can play a good role in protection.The inspection tool has been successfully applied in the industrial field of the China-Myanmar crude oil pipeline(Chinese section).Many times,the application and excavation results show that the pipeline internal corrosion detection technology based on piezoelectric ultrasonic technology is fully applicable to the working conditions of China-Myanmar crude oil pipeline(Chinese section),and the detection data is accurate and reliable.It provided new and effective technical support and guarantee for the safe and stable operation of the China-Myanmar crude oil pipeline.
