Abstract

Pipeline is the main transportation mode of oil and gas resources. However, most pipelines are subject to harsh natural environments, such as external force and temperature fluctuations in addition to the adverse environment. The use of ultrasonic guided wave based nondestructive testing technology for long-term monitoring of the stress in pipeline structure can effectively avoid such disasters. This paper focuses on the propagation characteristics of longitudinal guided waves in pipeline structures subjected to axial stress, to examine the possible applications of various guided wave modes for the stress detection in pipeline structures. Analyzing the generated numerical results, a method for estimating the stress from the velocity variation is proposed. The proposed method has practical applications for pipe stress monitoring using guided waves.
