Research and Outlook on Leak Detection Technology of Natural Gas Pipelines

The natural gas pipeline leak can cause major accidents and hazards. It is crucial to detect a leak timely and to determine the leakage point. In this paper, domestic and international long-distance pipeline leak detection and location technology in recent years, are introduced scientifically and pointed out the advantages and disadvantages of each method. With the development of oil and natural gas, pipeline transportation is becoming increasingly important in the national economy. In the meantime, to acquire a reliable and economic leak location method is extremely essential. This article also makes a systematic exposition for possible development of the leak detection and location technology in the near future.
