Method for detection of deformation stress of large-diameter and high-pressure pipeline under complex terrain
China-Russia Eastern Gas Pipeline is characterized by ultra-large diameter, high grade steel (X80) and high pressure rating. It is located in the area with geologically active permafrost and semi-permafrost zones in the north, where is prone to geological disasters. Hence, the non-design load may br...

China-Russia Eastern Gas Pipeline is characterized by ultra-large diameter, high grade steel (X80) and high pressure rating.

Therefore, high-precision measurement of stress value during pipeline operation will be crucial to its safety assessment. According to the actual service conditions of China-Russia Eastern Gas Pipeline, the propagation time of ultrasonic LCR wave in the elastic-plastic deformation of X80 steel was measured, and the propagation rule of ultrasonic LCR wave in the elastic deformation and plastic deformation of X80 steel was explored on the basis of studying the theory and method of detecting pipeline stress by ultrasonic LCR wave.
