Sealing with pressure is a very important industrial technology, which has been widely used in many industrial fields. This technology can stably block pipes or containers for maintenance, overhaul, cleaning, replacement of parts and other operations. Before performing this operation, you need to understand the process and steps of expanding tape pressure plugging in detail to ensure the successful completion of the work. Below, I will walk you through the process of plugging with pressure.

1. Preparation

Before performing a plugging operation with pressure, you need to make necessary preparations. The first is to clean the inside of the pipe or container to ensure that no impurities and chemicals remain. It is then necessary to check and ensure that the expansion tape seal is in good condition to prevent any damage during operation.

Second, choose the appropriate sealing method

Before performing a sealing operation with pressure, the appropriate sealing method needs to be selected. This process involves different types of sealing devices and valves, such as blinds, clamps, etc. To ensure that the correct sealing method is selected, it is necessary to consider the nature of the pipeline or container and normal working pressure, temperature and other conditions.

Third, install sealing equipment

Once the appropriate sealing method has been selected, a sealing device needs to be installed. When installing sealing devices, follow the correct installation procedures and specifications. All seals need to be inspected and tested to ensure their quality during operation.

Fourth, expand the sealing method

After the sealing device is installed, additional sealing methods need to be added to the pipe. This is to ensure the smoothness of work and the stability of operation. For example, if a blind seal is used, it is also necessary to add a clamp or flange in order to improve the reliability of the seal.

5. Apply stress tests

After installing all seals and extending seals, a pressure test is required. This is to ensure that all seals can withstand the pressure under normal operating conditions. Stress testing requires multiple levels of testing, each testing different operating pressures. For example, for high temperature and high pressure pipes and containers, multiple pressure tests are required.

6. Apply pressure

Once the stress test is complete, you can start applying the pressure. This is a very technical job and before proceeding, it is necessary to ensure that all sealing devices are fully coupled in accordance with the correct procedures. If any adjustments need to be made, they must be done before the pressure. After the overwriting pressure is completed, the operation can be evaluated to evaluate the test results as well as the integrity and operability of the seal.

7. Maintenance and maintenance

Finally, pay attention to maintenance and maintenance. Equipment with a pressure plug requires regular maintenance and maintenance to ensure that all seals are working properly and to avoid operational accidents due to undetected faults or wear.

In short, pressure plugging technology is a very important industrial technology, in the process of implementation, need to be very careful. The above processes and steps ensure smooth and stable operation with a pressure plug, while providing you with some basic information on how to proceed.
