Pressure plugging is a stabilizing measure in piping systems and containers, through the use of special plugging devices, under the application of a certain pressure, effectively prevent the leakage of fluid or gas. Pressure plugging has a variety of functions and applications, which I will describe in detail below.

1. Leakage control: The main function of pressure plugging is to prevent leakage. When a leak occurs in a pipeline or container, the use of a pressure sealing device can quickly and effectively block the leak site, avoid the spread of harmful substances, and protect the stability of personnel and the environment.

2. Maintenance and overhaul: Pipes and containers may suffer wear, corrosion or other damage during use, requiring maintenance and overhaul. A pressure plug can provide a temporary plug during maintenance and overhaul, avoiding the time and cost of downtime and emptying the system.

3 Prevent pollution: In industrial production, some fluids or gases may cause pollution to the environment. The pressure plug can seal the pipe or container in an emergency, prevent harmful substances from leaking, and protect the cleanliness of the surrounding environment.

4. Pressure test: Before the pipeline or container is put into use, pressure test is required to ensure its reliability. A pressure plug can provide a temporary plug measure to allow pressure testing to be performed to ensure that the system's pressure performance meets design requirements.

5. Pipeline cleaning and maintenance: there will be impurities, sediments or blockages in the pipeline system, which need to be cleaned and maintained. The pressure plug can temporarily block a section of the pipeline, which is convenient for cleaning, maintenance and replacement of the pipeline.

6. Emergency response: In emergency situations, such as fire, explosion, etc., pressure sealing can block pipelines or containers, avoid the spread of fire or the spread of explosive materials, and protect the stability of personnel and property.

7. Prevent gas and liquid leakage: pressure sealing can effectively block the leakage of gas and liquid, prevent them from entering the area they do not want to enter, and avoid the occurrence of accidents.

8. Improve stability: Pressure plugging can provide additional stability assurance, making the pipeline and container system more stable and reliable.

9. Extend the service life: Pressure sealing can provide emergency sealing measures to extend the service life of the pipeline and container system when there is a problem.

In short, by providing temporary plugging measures, it can protect the stability of people and the environment in various situations, prevent leaks and pollution, and improve the efficiency and reliability of industrial production. It is widely used in various industries and is an important stabilization measure and tool.
