Problems solved by technology
The research shows that in the supercharging station, due to the difference in the vibration amplitude of the two adjacent pipelines, there is a slight movement between the two adjacent flanges, which causes the fatigue life of the flange connection to decrease. Air leakage occurs at the flange connection

The invention provides a safety protection device for a natural gas booster station pipeline for preventing pipeline flange leakage, and relates to the technical field of safety of natural gas pipelines. The safety protection device for the natural gas booster station pipeline comprises a left pipeline and a right pipeline, the left pipeline and the right pipeline are connected through a flange, afirst protective cover is arranged outside the flange in a sleeved mode, and the two ends of the first protective cover are in sealing connection with the outer wall of the left pipeline and the outer wall of the right pipeline respectively to form a first gas storage cavity; and vibration damping devices are arranged between the outer wall of the left pipeline and the inner wall of the first protective cover and between the outer wall of the right pipeline and the inner wall of the first protective cover respectively. The protective device can prolong the service life of a flange connectingpiece, so that the possibility of air leakage between the flanges is reduced, and the safety performance of the booster station pipeline is improved.
Description
technical field [0001] The invention relates to the technical field of natural gas pipeline safety, in particular to a safety protection device for a pipeline of a natural gas booster station. Background technique [0002] The natural gas booster station is the main link of natural gas production and transportation. With the development of my country's natural gas industry, the establishment of natural gas booster stations will become more and more common. Once a leakage accident occurs at the booster station, it will affect the smooth and safe gas transmission downstream of the pipeline, thereby affecting industrial production and social stability. [0003] In the natural gas booster station, many pipelines need to be laid to connect the compressors, and the pipelines are connected by flanges. Since elastic gaskets are also arranged between the flanges, the flange connections between the pipelines have problems. A certain diameter mutation. The pipeline in the booster sta...
