Pressure closure construction is a common engineering technique used to seal and seal operations in pipes, containers or other equipment. It is a complex job that requires experienced technicians to operate. The following will introduce the steps and precautions of the construction of the expansion tape pressure sealing in detail.

Sealing with pressure refers to the sealing and sealing operation in the pipeline or container. It is usually used in the stable maintenance of pipelines, equipment overhaul, pipeline reconstruction and other work. Pressure sealing construction can effectively prevent media leakage, reduce production disruption time, and ensure the workplace.

First of all, before carrying out the pressure plugging construction, it is necessary to carry out adequate preparation work. This includes conducting an assessment of the construction site, understanding the structure and characteristics of the pipe or container, identifying the materials and tools required for construction, and ensuring that the construction personnel have the necessary skills and knowledge.

Secondly, when carrying out the sealing construction with pressure, it is necessary to select the appropriate sealing material. Common sealing materials include rubber sealing tape, metal sealing tape, expansion sealing tape and so on. When selecting the sealing material, it is necessary to consider the nature of the medium, temperature, pressure and other factors to ensure the sealing effect.

Next, determine the location of the plugging point according to the actual situation. For pipes, the plugging point is usually located at the valve or pipe connection of the pipe. For containers, the plug point is usually located at the entrance, exit, or other leak point of the container.

Then, the plugging operation is performed. First, clean the surface around the plug point to make sure it is smooth and clean. Then, place the plugging material correctly on the plugging point and use the tool to fix it. When placing the sealing material, it is necessary to ensure that it is in close contact with the surface of the pipe or container to achieve an effective sealing effect.

After the plugging operation is complete, a pressure test is required. The pressure test is to verify the effect of the plug and ensure that no leaks exist. Before the pressure test, it is necessary to close the relevant valve, gradually increase the pressure to the set value, and maintain it for a period of time. If the pressure is stable and no leakage occurs, the plugging operation is successful. Finally, the construction is completed and the cleaning work is carried out. After the plugging operation is complete, clean the construction site to ensure that no plugging materials or tools are left behind. At the same time, the relevant valve needs to be restored to the normal state for subsequent work operation.

It is important to note that pressure sealing is a high-risk job and must be performed by trained and certified technicians. During the construction process, the relevant codes and operating procedures must be observed to ensure the safety of the workplace.

To sum up, the construction of sealing with pressure is a complicated and important engineering technology. It requires an experienced technician to operate and requires adequate preparation. During the construction process, it is necessary to select the appropriate plugging materials, correctly place and fix the plugging materials, perform pressure tests, and carry out construction completion and cleaning work. Through the correct sealing construction with pressure, the media leakage can be effectively prevented and the stability of the workplace can be ensured.
