Topic: Steel Pipeline Damaged Detection Without Removing Cladding
Abstract: With developments in electric power, energy, and transportation industries in china, the number of steel pipelines is now increasing rapidly as energy transportation through pipelines has unique advantages. Since oil & gas within the pipelines are flammable and explosive, pipeline failures would cause many casualties and huge economic losses, also resulting in serious pollution to the environment. Therefore, pipeline damage inspection is of top priority to insure the safety of pipelines. However, the existed technologies for pipeline damage external inspection demand removing of the pipeline cladding which makes these technologies of high cost and low efficiency. Meanwhile, the removing of the pipeline cladding may cause new damages to the pipeline. In order to solve this both scientific and engineering challenge, a new pipeline detection technology based on harmonic magnetic field was proposed from our lab. This talk will present a systematic report on the research of this technology which mainly includes: 1) the detection mechanism; 2) design on the harmonic signal excitation source; 3) design on a multi-space full tensor magnetic gradient detection array probe and its magnetic focusing mechanism; 4) coupling law of pipeline damage and magnetic anomalies along with its decoupling method; 5) pipeline damage identification and positioning algorithm; 6) engineering applications.
