Field-pipeline operations are more easily affected by complex environment in comparison of common long-distance pipeline. Its failures such as leakage demand to be dealt with more urgently and efficiently. This paper proposes a leakage detection method based on the improved fast differential algorithm on the basis of negative pressure wave detection theory. The method can achieve high sensitivity...
Leakage accidents in oil transmission pipelines not only cause loss of material, but also bring about hidden troubles for people's property and the environment. Pipeline leakage accidents occur frequently in recent years, particularly in those developing countries, and most of which were done destructively. Negative pressure wave technique is an effective method for paroxysmal oil leakage detection...
Static pressure method and dynamic pressure method were commonly used in pipeline leak detection. Advantages and disadvantages of the two methods were analyzed and a dynamic pressure sensor was designed for long-range oil and gas transmission pipeline. In order to improve its performance, experiments of circuit simulation was carried out on the main part of the sensor. Application experiments show...
