Pressure plugging is a common engineering technique used to control the flow of fluid in a piping system or equipment. It is usually used during construction, maintenance or inspection to ensure the stability and effectiveness of the work. This article will introduce the process of the compression seal in detail.

First, a series of preparatory work is required before plugging with pressure. This includes identifying the plugging area, selecting the appropriate plugging materials and tools, checking the condition of equipment and pipes, and ensuring that the construction personnel have the necessary protection to begin the actual process of plugging with pressure after the preparatory work is complete.

The process of sealing with pressure is mainly divided into the following steps:

1. Clean and prepare the work area: First, clean and prepare the work area to ensure that there is no debris or dirt that will affect the effective sealing. This may require the use of cleaners and tools to remove dirt.

2. Location of the plugging point: Before determining the plugging point, it is necessary to understand the structure and design of the pipeline system. Depending on where plugging is required, use measuring tools and fluid detection instruments to determine the exact plugging point.

3. Prepare plugging materials and tools: Select proper plugging materials and tools based on the plugging point requirements. Common sealing materials include air cushion, expansion tube plug, rubber gasket and so on. Ensure the quality and suitability of the sealing materials, and prepare the work as required, such as wrenches, bolts, etc.

4. Plugging operation: Insert the selected plugging material into the plugging point, and adjust and position it as required. Ensure that the sealing material is fully sealed and can withstand the pressure or equipment required to secure and stabilize the sealing material.

5. Apply pressure: After the closure is complete, pressure needs to be applied to test the effectiveness of the closure. Use a pressure measuring instrument to measure the pressure and ensure that the pressure is in a stable range. Finding leaks or other problems requires adjustments.

6. Monitoring and maintenance: Once plugging is complete and the pressure is stable, the plugging point needs to be monitored. Check the pressure regularly and ensure the stability of the sealing materials and tools. If an abnormal condition is found, take measures to repair or replace it in time.

Throughout the process of sealing with pressure, stability is essential. Construction personnel must follow the operating procedures and wear necessary personal protective equipment, such as gloves and goggles. In addition, they should be familiar with relevant emergency handling procedures and be prepared to respond to emergencies.

In summary, the process with a pressure plug includes cleaning preparation, locating the plug point, preparing materials and tools, plugging operation, applying pressure, and monitoring and maintenance. Through the correct and reasonable stabilization measures, the pressure sealing can effectively control the fluid and ensure the stability and durability of the construction process.
