摘要

Long-range guided wave inspection is a new emerging technology for rapid pipeline inspection. In this paper, a digital signal processing method based on a synthetic technique and a direction control technique is introduced to process pipeline inspection signals. With this method, signals from different directions can be separated and structures including defects can be detected. Working with an instrument developed by Petrochina Pipeline R & D Center, this method is already used in inspection of in-service pipelines.
