Pressure plugging is a common engineering technique used to control the flow of liquid, gas, or dust in a pipe or container. The correct application of these technologies is essential to ensure the efficient operation of the project. Before performing a pressure plug operation, there are several key considerations to keep in mind to ensure smooth operation and minimize potential wind. Here are some important things to note:

1. Qualification and training: Only personnel who have been specially trained and familiar with the relevant safety procedures can perform the operation with pressure sealing. Ensure that operators have the necessary skills and knowledge to understand the risks and measures of operation and are able to use relevant tools and equipment correctly.

2. Tools and equipment: Select the appropriate tools and equipment to perform the pressure plugging operation. These tools and equipment include but are not limited to sealants, gaskets, clamps, pressure gauges, etc. Ensure that the quality of these tools and equipment is reliable and that regular maintenance and inspections are carried out to ensure that they are working properly.

3. System pressure: Before plugging with pressure, it is necessary to understand the actual pressure in the pipeline or container. Ensure that the tools and equipment used can withstand the appropriate pressure to prevent accidents. Select the appropriate sealing material and operation method according to the actual situation.

4. Sealing material selection: Select the appropriate sealing material according to the material, pressure and temperature of the pipeline or container. Ensure that the selected material has characteristics such as resistance to pressure, corrosion and high temperature, and can ensure good sealing performance.

5. Plugging process: When plugging with pressure, it must be carried out in strict accordance with the operating rules. Ensure that the sealing material is properly installed and maintains proper fastening force. For high pressure systems, the way of gradually increasing the pressure should be blocked to ensure stability.

6. Monitoring and inspection: In the process of sealing with pressure, the pressure and temperature of the sealing part should be regularly monitored and checked. If any abnormal situation occurs, take immediate measures to stop plugging and troubleshoot the problem.

7. Unlocking process: After completing the sealing with pressure, the pressure must be carefully relieved, and the sealing material must be gradually relaxed. Ensure reliable unsealing process to prevent accidental damage caused by sudden release of material.

8. Protection: When performing the operation with pressure closure, the operator should wear appropriate personal protective equipment, including safety glasses, gloves, ear plugs, etc. Ensure that other personnel and equipment in the work area are also properly protected.

9. Emergency plan: Emergency plan must be prepared and operator trained before pressure plugging operation. The plan should include emergency evacuation routes, measures and emergency contact information.

To sum up, the correct operation with pressure plugging requires strict adherence to procedures and precautions. Operators should have the necessary skills and knowledge and choose the appropriate tools and materials. During operation, monitoring and inspection should be carried out, and emergency preparedness should be prepared. It is important to ensure the reliability of operations to protect people and equipment.
