In various industries, sealing with pressure is a common technical means, which is widely used in different occasions. Some common applications are described below in order to better understand and understand the broad application of this technology.

1. Oil and gas industry: In the process of oil and gas exploitation, pressure sealing technology is widely used in the construction and maintenance of wellheads, oil and gas Wells. In the aspect of wellhead sealing, the expansion tape sealing can effectively prevent oil and gas leakage, ensure the safety of personnel and environmental protection. In oil and gas well construction, pressure plugging can be used to control wellhead pressure and prevent formation fluid leakage.

2. Chemical industry: In the chemical production process, pressure sealing technology is often used for the maintenance and overhaul of pipeline systems, reactors and storage tanks. When the pipeline or equipment needs to be repaired, the pressure plug can effectively close the pipeline, prevent the leakage of the medium, but also prevent the gas or liquid from entering the equipment, affecting the quality of maintenance.

3. Power industry: In the process of power transmission and distribution, pressure plugging can be used to block the maintenance and repair of transmission lines or transformers. By blocking the power equipment, it can ensure stable construction, reduce the power system outage time, and improve work efficiency.

4. Construction industry: In construction, pressure sealing is widely used in concrete construction, pipeline installation and hydropower projects. In concrete construction, pressure sealing can be used to seal concrete cracks, prevent concrete leakage and improve construction quality. In pipeline installation, pressure closure can be used to control water flow and prevent water leakage. In hydropower projects, pressure plugging can be used to block water sources and prevent water leakage.

5. Food and pharmaceutical industry: In food production and pharmaceutical production, pressure sealing is often used to control the pressure, temperature and liquid level parameters in the production process. Through the sealing technology with pressure, the stability of the production process can be ensured and the quality of the product can be improved.

6. Sewage treatment industry: In the sewage treatment process, pressure sealing can be used to block pipelines and storage tanks, prevent sewage leakage and protect the environment. At the same time, the pressure sealing can also be used for the maintenance and overhaul of sewage treatment equipment to improve equipment reliability and work efficiency.

7. Aerospace industry: In aerospace engineering, pressure plugging technology is widely used in the plugging of propulsion systems, liquid oxygen systems and liquid hydrogen systems. By sealing with pressure, the stability and reliability of the propulsion system can be ensured, and the smooth flight process can be guaranteed.

To sum up, pressure plugging technology has a wide range of applications in various industries. Whether it is to protect personnel stability, prevent media leakage, or to improve work efficiency and product quality, pressure plugging has played an important role. With the continuous development of technology, it is believed that pressure plugging technology will continue to play an important role in more fields and make greater contributions to the development of all walks of life.
