Natural gas pipeline monitoring
With the rapid development of natural gas industry, the safety of natural gas pipeline is getting more and more attention. The safe operation of natural gas pipeline is directly related to the stability of national energy supply and the security of economic development. Natural gas pipeline monitoring is one of the most important means to ensure the safe operation of pipelines, through which potential problems of pipelines can be found in time and corresponding measures can be taken for prevention and maintenance. Through monitoring technology, potential pipeline problems can be detected in time, and corresponding measures can be taken for prevention and maintenance.
Natural gas pipeline monitoring working principle
Natural gas pipeline monitoring system mainly consists of data acquisition device, transmission channel and data processing terminal. The data acquisition device is responsible for collecting various data inside the pipeline. The transmission channel transmits the collected data to the data processing terminal, which processes, analyzes and stores the data.
In the natural gas pipeline, a large number of sensors and monitoring points are deployed for real-time collection of various data from the pipeline. These sensors transmit the collected data to the data acquisition device via signal lines. The data acquisition device will analyze and process the collected data, and then transmit the data to the data processing terminal via a communication device.
The data processing terminal further analyzes and stores the data according to the received data. It can judge whether there are abnormal conditions in the pipeline according to the pre-set algorithms and rules, and send timely alarms to the management personnel. At the same time, the data processing terminal can display the operation status of the pipeline in the form of charts, curves, etc., which is convenient for the managers to carry out real-time monitoring and analysis.
Natural gas pipeline monitoring indicators:
Corruption of food, bacteria and microbial reproduction is often accompanied by the release of organic volatiles, and the VOC sensor in the freezer with the freezer air circulation system can effectively monitor organic volatiles in all corners of the refrigerator: such as odors, rotten eggs ammonia-like substances, nitrogen gases, sulfur, and other substances that are generated during the process of food decay.
1、Pipeline pressure monitoring
By installing a pipeline pressure monitor on the pipeline, the pressure changes inside the pipeline are monitored in real time. Once the pressure is abnormal, the monitoring system will issue a warning signal to notify the relevant personnel to deal with it in time.
2、Gas leakage monitoring
Utilizing Combustible Gas Monitor, it monitors the methane concentration within the walls of the valve wells of the gas pipeline network and the adjacent underground space. Once there is a leakage, the monitoring system is able to give a quick alarm and take emergency measures quickly.
3、Vibration Monitoring in the Surrounding Area
Structural vibration and extrusion on the surface of the gas pipeline network and its surrounding locations may trigger rupture of the network, gas leakage, etc. Real-time monitoring of the structural health status at key stages through intelligent structural diagnosis can effectively prevent pipeline rupture and provide relevant early warning for gas leakage.
Currently, with the construction of urban lifeline safety project, the city’s infrastructure began to gradually move towards intelligent management, gas pipeline is no exception, the use of intelligent monitoring equipment real-time monitoring of the pipeline’s operating status, early detection of potential problems and take measures to prevent accidents. Through effective monitoring means, the risk of accidents can be reduced to ensure the safety and stability of natural gas transportation.
