How to convert natural gas high-pressure pipeline into medium-pressure pipeline

1. Installation of decompression device: Installing decompression device between high-pressure pipeline and medium-pressure pipeline can reduce the pressure of high-pressure natural gas to that required by medium-pressure natural gas.

2. Check the decompression device: After the decompression device is installed, it needs to be checked to ensure that the decompression device can work normally without any leakage or damage.

3. Connecting the pipeline: connecting the decompression device and the medium pressure pipeline to ensure the tightness and safety of the connecting pipeline.

4. Adjust the air pressure: After the pipelines are connected, it is necessary to adjust the air pressure to ensure that the natural gas pressure in the medium-pressure pipeline meets the requirements, and at the same time, it is necessary to ensure that there is no leakage or other potential safety hazards in the pipeline.
