Pressure plugging is a process used to ensure the tightness and stability of a piping system or container. In the construction process, it is often necessary to carry out pressure sealing operations to ensure construction quality and project stability. The following describes the definition, function, operation steps, and precautions of sealing with pressure in detail.

1. Definition:

Pressure sealing refers to the operation step that after the installation of the pipeline or container, the pipeline or container is completely sealed by applying pressure inside the pipeline or container and using pressurized gas or liquid sealing materials to ensure that no leakage or stability risks occur.

2. Function:

The role of pressure plugging is multifaceted:

- Ensure the tightness of the pipe or container: by applying pressure, the sealing material is filled into the pores of the pipe or container to stop the occurrence of leaks or air leakage.

- Protect the stability of construction personnel: the blocked pipeline or container can withstand normal operating pressure, prevent the occurrence of dangerous situations such as explosion and leakage - Prevent pollution: the blocked pipeline or container can effectively prevent the leakage of harmful substances, and avoid pollution and harm to the environment and human health.

3. Operation steps:

(1) Preparation:

- Identify the pipe or vessel that needs to be rewritten and sealed.

- Prepare the sealing materials needed, such as gas, liquid or tape.

- Check the environment and safety conditions around the pipeline or container to ensure the stability of the construction personnel.

2) Apply pressure:

- Determine the pressure required for construction and adjust it according to the design pressure and use requirements of the pipeline or vessel.

- Apply pressure with appropriate tools or equipment, such as pneumatic pumps, hydraulic pumps, etc.

- Pressure sensors and control systems can be set up as required to monitor and adjust the applied pressure) Plugging operation:

- Select the appropriate sealing materials according to the different types of pipes or containers, such as rubber gaskets, fillers, sealants, etc.

- Place the plugging material in place to ensure that the pores of the pipe or container are fully plugged.

- Make adjustments and corrections as necessary to ensure that the sealing material is in close contact with the pipe or container and that there is no air leakage or leakage.

(4) Testing and confirmation:

- After plugging is complete, use relevant equipment for leak testing to ensure the tightness of the pipe or container.

- Check the installation of the sealing material to ensure that there is no deviation or incomplete sealing.

- Pressure maintenance tests can be carried out to verify the stability of the pipe or vessel under normal operating pressure, as required.

4. Precautions:

- Be familiar with and master the relevant operating procedures and stability requirements before performing a pressure plug operation.

- The selection and use of sealing materials should comply with relevant standards and specifications to ensure that it has good sealing performance and pressure resistance.

- During the construction process, attention should be paid to the stability of the operator to avoid accidents.

- After plugging, the construction site should be cleaned and organized to keep the environment clean and stable.

In SUMMARY:

Sealing with pressure is an important construction step that ensures the tightness and stability of a pipe or container by applying pressure and using the appropriate sealing material. In the operation process, it is necessary to strictly abide by the relevant operating procedures and stability requirements to ensure the construction quality and project stability.
