Main risks and management measures for long-distance natural gas pipeline stations

Due to the unique nature of natural gas energy, there are extremely strong risks in its management and transportation, especially for long-distance natural gas pipeline stations, which pose numerous safety risks. Therefore, in order to reduce the occurrence of safety accidents in long-distance natural gas pipeline stations and minimize the risks existing in long-distance natural gas pipeline stations, relevant personnel must strengthen their attention to the operation of long-distance natural gas pipeline stations. Through in-depth understanding of the actual operation situation of long-distance natural gas pipeline stations, they should prepare risk management measures in advance to deal with long-distance natural gas pipeline stations, To ensure the safe and stable operation of long-distance natural gas pipeline stations, and promote the harmonious development of the natural gas industry in society.

1、 Main risks of long-distance natural gas pipeline stations

1. Risk of natural gas leakage from pipelines

In the actual operation of long-distance natural gas pipeline stations, the most common risk is natural gas leakage. Generally, the reasons for natural gas leakage in stations can be summarized as two types: pipe design reasons and pipe performance degradation.

Firstly, pipeline design is mainly due to the unique situation of long-distance natural gas pipeline stations, especially the extremely high requirements for pipeline materials. If pipeline designers cannot design suitable pipelines with sufficient gas flow rate, compressive capacity, and resistance to other impacts based on the actual needs of the station, it will be difficult to ensure the safety of long-distance natural gas pipeline stations.

Secondly, the decrease in material performance is mainly due to the special environment of long-distance natural gas pipeline stations, where many pipelines are buried underground. These pipelines are exposed to soil for a long time underground and are very susceptible to corrosion, leading to continuous thinning of the pipeline wall. In addition, the internal and external pressure on the pipeline makes it more prone to natural gas leakage, which can cause safety accidents.

2. Risks caused by natural disasters

Due to the long distance of natural gas transported at long-distance natural gas pipeline stations, there are certain natural disaster risks such as floods, earthquakes, and mudslides during the transportation process with a long geographical span. Once these natural disasters occur, they can cause damage to long-distance natural gas pipelines, leading to cracks or fractures, and affecting their normal use. Natural disasters have a significant impact on long-distance natural gas stations, and such disasters cannot be known in advance. Therefore, in the actual management of long-distance natural gas pipeline stations, relevant personnel need to strengthen their understanding of the weather and natural conditions in various regions where long-distance natural gas pipelines operate, and develop corresponding protection measures based on specific situations to avoid the risks brought by natural disasters as much as possible.

3. Risk of equipment failure

Because the equipment in long-distance natural gas pipeline stations is not only diverse, but also operates in a very complex environment, which is prone to equipment failure problems, thereby bringing equipment failure risks to long-distance natural gas pipeline stations. Among these risks, the most common are equipment failure, control system failure, and pipeline leakage.
4. Risks caused by station overpressure

In order to ensure the better operation of long-distance natural gas pipeline stations, the pressure set by station equipment is often relatively high, and this high pressure setting is prone to overpressure problems due to improper pressure control, which can lead to safety accidents at long-distance natural gas pipeline stations due to overpressure.
2、 Risk management measures for long-distance natural gas pipeline stations

1. Strengthen training and education on station risk management

2. Carry out relevant management and maintenance work for the station yard

3. Improve the risk management and control system of the station
