Sealing with pressure is a common operation process, mainly used for the sealing and stable operation of pipelines, containers and other equipment. The following is a detailed process of sealing with pressure, including preparation work, operation steps and precautions.

1. Preparation

1. Collect related documents, including technical parameters, pressure levels, types and specifications of plugging materials. Prepare tools and materials, such as sealing rubber rings, sealing gaskets, screws, hammers, compensators, and pressure gauges.

3. Check the device status: Ensure that the device is operating normally without leakage, damage, or other suspicious problems.

2. Operation steps

1. According to the technical parameters and pressure level of the equipment, determine the material specifications and sizes required for plugging.

2. Determine the blocking point: according to the process needs and equipment structure, determine the location of the blocking point, and clean up the debris around the blocking point. Installing the sealing rubber ring: Insert the sealing rubber ring into the sealing point to ensure that it is tightly fitted to the device surface.

4. Install plugging bolts: Insert the plugging bolts into the holes on the sealing rubber ring and tighten them one by one using a wrench.

5. Install the sealing gasket: Place the sealing gasket on the sealing bolt and ensure that it is tightly fitted with the sealing rubber ring and the device surface.

6. Tighten bolts: Use a wrench to tighten the sealing bolts one by one to ensure sealing performance at the sealing points.

7. Install the compensator: If you need to perform compensation operations, install the compensator correctly at the plugging point and adjust the compensator according to the device requirements.

8. Pressure test: Use a pressure gauge to test the plugging point to ensure that the plugging point can withstand the predetermined working pressure.

9. Monitor the plugging point: After the plugging operation, continuously monitor the pressure and temperature and other parameters at the plugging point to ensure stable operation.

Third, precautions

1. The operator must be familiar with the relevant knowledge and operating procedures of the equipment to ensure the stability of the operation.

2. Before plugging the device, ensure that the device is completely emptied and deflated.

3. In the sealing operation, it is necessary to strictly follow the process requirements and regulations to avoid any deviation.

4. When tightening the bolts, the force should be even to avoid too tight or too loose.

5. When performing pressure tests, it is necessary to use a pressure gauge that meets the requirements and calibrate its accuracy.

6. After the plugging operation is complete, clean up the site in time to ensure that there are no debris and other hidden dangers.

The above is a detailed sealing process. Strictly follow the operation procedures and precautions to ensure the stability and reliability of sealing operations. In actual operation, it is also necessary to adjust and supplement according to the equipment and process requirements.
