Sealing with pressure refers to the process of sealing the equipment in industrial production in order to ensure the smooth operation of the equipment and prevent leakage. This process is very important because if there are any leaks or faults, accidents can occur, causing serious harm to the production line and workers. Therefore, it is necessary to carry out strict pressure plugging detection on the equipment before leaving the factory.

Pressure plugging testing is performed by applying a certain amount of pressure to the device and then observing whether the device is able to maintain a sealed state. This process usually involves the following steps:

1. Preparation: Before starting the plugging test, you need to prepare the equipment. First, you need to make sure that the equipment is installed and that all the connecting parts are secured. Secondly, it is necessary to check whether the sealing materials such as the sealing gasket and sealant of the equipment are intact, and if there is damage, it needs to be replaced in time.

2. Apply pressure: After the preparation is complete, you can begin to apply pressure. Usually a liquid or gas is used as a medium to apply pressure. Before applying pressure, it is necessary to ensure that the pressure source and pressure gauge are working properly and are able to provide stable pressure. Apply appropriate pressure according to equipment requirements and design requirements.

3. Observation and detection: After applying pressure, it is necessary to observe whether the device can maintain a sealed state. This can be done by visually observing the surface of the device for leaks, or by using a leak detection instrument. At the same time, it is also necessary to check whether the reading of the pressure gauge is stable and there is no obvious fluctuation. If the device can remain sealed and there is no leakage, it indicates that the plugging test with pressure is qualified.

4. Record the results: In the process of conducting the plugging test with pressure, the results and observations of each step need to be recorded. These records help to trace and analyze the performance of the equipment and troubleshoot problems when they occur. Records should include pressure values applied, observed leaks, and other relevant information.

To sum up, pressure plugging detection is one of the key steps to ensure the sealing performance of equipment. By applying the appropriate pressure and observing whether the equipment can remain sealed, you can promptly troubleshoot the equipment for leaks or other problems. This process needs to be strictly carried out and the results recorded for subsequent analysis and improvement. To ensure that the sealing performance of the equipment meets the requirements, in order to ensure the operation of the production line and the safety of the staff.
