Leakage Monitoring

On large-scale pipelines at a water supply capacity of 5-10 m3/s, the bursted flow can reach hundreds to thousands of cubic meters within a few minutes, which could trigger secondary disasters in the densely populated areas. But the accident is hard to be monitored and found, because the leakage flow is often only 1% to 5% of the water supply capacity. This paper presents the simultaneous manometry for the burst and leakage monitoring along the pipelines. The research found that it can alarm timely in 3min to 5min and provide key information such as detonation location and the amount of the explosion leakage. The method has been applied to Xijiang River Diversion Project in China and the water supply capacity is 3.5 million m3/d(40.5m3/s).

This work defined an Eulerian-based computational model compared with regression of the relationship between the dependent and independent variables for water hammer surge wave in transmission pipeline. The work also mentioned control of Unaccounted-for-Water (UFW) based on the Geography Information System (GIS) for water transmission pipeline. The experimental results of laboratory model and the field test results showed the validity of prediction achieved by computational model.

Leakage Monitoring

Oil and gas pipeline transportation, as a relatively safe way of oil and gas transportation, undertakes most of the transportation tasks of crude oil and natural gas. Oil and gas pipeline accidents affect a wide range of consequences. Therefore, the oil and gas pipeline leakage detection is paid more and more attention. In this paper, ultra-low power methane gas sensor is selected to collect methane gas concentration in the air, and wireless network technology is used to build a wireless network sensor system with 4G function. Through the sensor distribution along the pipeline, it can intuitively and accurately judge whether there is a micro-leakage in the pipeline, and understand the diffusion situation after the leakage. The sensor system has high reliability and stability, and has high value of popularization and application.
