Pressure plugging is a technique that applies pressure to a pipe, container, or device to stop the leakage or loss of a liquid, gas, or solid material. It is commonly used in chemical, petroleum, gas and other fields to maintain the stability and reliability of the system. The performance and characteristics of sealing with pressure include the following aspects:

1. Force tolerance: The sealing material with pressure must be able to withstand the high pressure applied inside the system. This usually requires the material to have high strength and wear resistance to ensure long-term sealing effect.

2. Sealing performance: The sealing material with pressure must have excellent sealing performance to ensure that the medium of the system department will not leak or lose. It effectively prevents gas, liquid or solid substances from leaking into the external environment through interfaces or pores in pipes or equipment.

3 Chemical corrosion resistance: with pressure sealing materials in a variety of chemical corrosion performance. Different media may cause corrosion or corrosion of the material, because the appropriate material must be selected to ensure that it can be effectively blocked under different working conditions.

4. Temperature resistance: the pressure seal can withstand the pressure and temperature under high or low temperature working environment. For high temperature environments, the material must have high temperature resistance to prevent leakage caused by thermal expansion and contraction. For low temperature environments, the material must have low temperature resistance to prevent brittle fracture caused by low temperature.

5. Wear resistance: Because the sealing materials with pressure may be affected by friction and wear during use, they must have good wear resistance. This ensures that the material has a long life and is not vulnerable to damage or wear, thus maintaining the sealing effect.

6. Adjustability and reusability: The sealing material with pressure should be adjustable to adjust and install according to specific needs. In addition, the pressurized sealing material should be reusable so that it can be easily removed and reinstalled if needed.

7. Stability performance: The sealing material with pressure should meet the relevant stability standards and regulations to ensure stability during use. This includes preventing hazards such as spontaneous combustion, explosion, or the release of harmful gases.

8. Pipeline or equipment protection performance: the sealing material with pressure should be able to effectively protect the pipeline or equipment during the sealing process to prevent it from being damaged or destroyed. This can extend the service life of the system and improve its reliability and stability.

In summary, the performance and characteristics of pressure sealing include pressure resistance, sealing performance, chemical corrosion resistance, temperature resistance, wear resistance, adjustability and reusability, stability, and pipeline or equipment protection performance. These features are designed to ensure the reliable and efficient operation of the system to meet the needs of various industrial and chemical sectors.
