Sealing with pressure is an important construction process, mainly used for the sealing and leakage prevention of pipelines, containers or equipment. Its purpose is to ensure the stability and reliability of the system and prevent leaks and damage. The following is a detailed construction process of expansion tape sealing, including the necessary steps and precautions.

1. Preparation:

Before performing a pressure plug, adequate preparation is required. This includes checking and clearing the work area to ensure that there are no debris or obstructions. It is also necessary to check and test the availability and conformity of related equipment, tools and materials.

2. Preparation of pipes or containers:

A series of preparatory work on the pipe or vessel is required before a pressure plug can be performed. First, the surface needs to be cleaned and de-rusted to ensure that the surface is smooth, free of dirt and rust. Then, check the integrity of the pipe or container to make sure there aren't any cracks, breaks, or leaks.

3. Selection of sealing materials:

According to the specific construction needs, choose the appropriate sealing materials. Commonly used sealing materials include rubber plug, rubber ring, sealing paste, etc. When selecting the sealing material, it is necessary to consider the characteristics of temperature, pressure and medium to ensure that the material can withstand the corresponding working conditions.

4. Selection of plugging method:

According to the specific construction needs, choose the appropriate plugging method. Common plugging methods include rubber plug plugging, expansion plugging, plugging paste plugging and so on. When selecting a sealing method, it is necessary to consider the size, shape and material of the pipeline or container to ensure that the sealing method can be effectively blocked.

5. Plugging operation:

Before starting a pressure plug, ensure that all operators are wearing personal protective equipment such as gloves, goggles, and earplugs. Then, perform the corresponding plugging operation according to the selected plugging method. The specific steps may vary depending on the plugging method, but generally include the following basic steps:

- Insert the sealing material into the inlet of the pipe or container and ensure that the sealing material is tightly fitted;

- Use appropriate tools or equipment to expand or fix the sealing material to ensure the sealing effect;

- Perform pressure test or leak detection as required to ensure good plugging effect.

6. Treatment after plugging:

After plugging is complete, perform related operations. First, the sealing material is removed from the pipe or container and cleaned and inspected. The plugging material is then treated and recycled to reduce the environmental impact. Finally, clean up the work area and make relevant records and reports.

In the construction process with pressure sealing, it is also necessary to pay attention to the following matters - the relevant stability specifications and operating procedures should be followed to ensure that the construction process is stable and reliable;

- During the construction process, technical attention should be paid to the environmental conditions and pressure changes in the working area, and timely adjustment of sealing methods and operations;

- During the construction process, the pressure and temperature should be strictly controlled to avoid exceeding the bearing capacity of the sealing material;

- During the construction process, the sealing effect should be closely monitored to ensure the integrity and tightness of the sealing material.

In short, sealing with pressure is a technically demanding construction process that requires adequate preparation and fine operation. Only under the premise of strictly following the construction regulations and precautions can the reliability and long-term stability of the sealing effect be guaranteed.
