Pressure plugging is a common technique used to control, plug, and maintain pipelines, equipment, or systems. It has a variety of functions, including the following:

1. Plugging function: With pressure plugging can be used to temporarily plug pipes or equipment. For example, when plumbing equipment needs repair, replacement parts, or work, a pressure plug plugs it to stop fluid or gas leakage or diffusion. This is a stabilizing measure that protects staff and equipment from potential hazards.

2. Leak repair function: pressure plugging can also be used to repair leaks in pipelines or equipment. By selecting the right plugging material and method, you can quickly and effectively repair the leak point, stop the fluid or gas leak, and restore the normal operation of the pipeline or equipment. This saves time and costs and reduces disruption to the production process.

3. Test and inspection function: Pressure sealing can also be used to test and detect the sealing performance of pipelines, equipment or systems. By plugging specific parts or areas, they can be tested under high pressure to ensure pressure resistance and sealing performance. This can help identify potential problems and defects and take timely steps to repair or replace them.

4. Isolation function: Pressure plugs can be used to isolate specific parts of pipelines, equipment or systems. By blocking a specific connection point or valve, this part can be cut off from other parts and stop the flow of media. This can facilitate repair, maintenance or replacement work while avoiding downtime and interference to the entire pipeline, equipment or system.

5. Regulation and control functions: pressure plugging can also be used to regulate and control the flow of fluids or gases. By adjusting the type, size and location of the sealing material, the passage and flow of the fluid or gas can be changed to meet specific needs and requirements. This can provide flexibility and convenience in some special situations, such as emergencies, temporary work or commissioning phases.

In summary, pressure plugging has a variety of functions and can be used to plug, repair, test, isolate and regulate pipelines, equipment or systems. It is an important technical means, widely used in petroleum, chemical, energy, pharmaceutical, water treatment and other industries, to provide staff with a stable, efficient and reliable working environment.
