Pressure plugging is a common engineering technique used to achieve closure and pressure control in pipelines, containers or equipment. In practical applications, the correct use of pressure sealing can ensure the stability of the working area, and effectively repair, detect, clean and stop leaks. This article will introduce the principle, tools and steps of sealing with pressure in detail, and provide the precautions and safety measures for using sealing with pressure.

First, the principle of pressure sealing

Pressure plugging is achieved by using a specially designed plugging device, placing it in the pipeline or equipment that needs to be blocked, and then applying pressure to achieve closure. The plugging device is usually made of elastic material, which automatically ADAPTS to the shape of the pipe or equipment and achieves a good sealing effect. During the construction process, by increasing or reducing the pressure, the sealing performance of the sealing device can be controlled and the stability of the system can be ensured.

2. Tools with pressure plugging

1. Plugging device: Plugging device is a key tool with pressure plugging, common plugging devices include plugging ball, plugging device, plugging pad and so on. Select a suitable plugging device according to the specific application scenario and requirements.

2. Pressure source: with pressure sealing need to apply pressure to achieve the sealing effect, common pressure sources include manual pump, pneumatic pump, hydraulic pump, etc. Choosing the right stressor can improve productivity and stability.

3. Pipe connection tools: When using pressure sealing, it is usually necessary to use pipe connection tools, including flanges, threaded joints, clamps, etc. Ensuring the quality and stability of the connection tool is critical to the successful implementation of a pressure plug.

Three, with pressure sealing steps

1. Safety preparation: Before using pressure sealing, first of all need to carry out safety preparation work. This includes cleaning work areas, ensuring the safety of personnel, and checking the integrity of tools and equipment.

2. Choose the right plugging device: choose the right plugging device according to the actual situation, and consider the material, size, pressure performance and other factors of the plugging device in the selection.

3. Install a plugging device: Insert the plugging device into the pipe or device to be plugged to ensure that the plugging device is properly installed and tightly sealed.

4. Connect the pressure source: Connect the selected pressure source to the plugging device, and ensure that the connection is firm and reliable.

5. Apply pressure: as needed, gradually apply pressure to ensure the sealing performance of the plugging device. In the process of applying pressure, it is necessary to check the status of the plugging device regularly.

6. Finish the job: After completing the plugging work, it is necessary to gradually reduce the pressure and remove the plugging device from the pipe or equipment. Before removing the plug device, ensure that the pressure is completely released and perform a full inspection.

Precautions and safety measures with pressure sealing

1. Strictly abide by the operating procedures: Before using the sealing with pressure, you should carefully read and understand the operation according to the procedures to avoid operating errors resulting in accidents.

2. Select the plugging device: Select the appropriate plugging device according to the actual situation, and ensure its quality and stable performance.

3. Regular inspection and maintenance: The plugging device will be affected by factors such as pressure and friction during use, so it needs regular inspection and maintenance to ensure its normal work.

4. Strict control of pressure: When applying pressure, it is necessary to strictly control the pressure size to avoid exceeding the pressure range of the plugging device to prevent stability accidents.

5. Personnel stability protection: In the process of using pressure sealing, necessary personnel safety protection measures should be taken, including wearing personal protective equipment, setting stability warning signs, etc., to ensure personnel stability.

To sum up, the correct use of pressure plugging requires strict compliance with the operating procedures, the selection of appropriate plugging devices, and the necessary safety measures. Through the correct use of pressure sealing, the stability of the working area can be ensured, and the maintenance, detection, cleaning and leakage prevention can be effectively carried out.
