Pressure plugging is a common pipe repair method used to repair a leaking pipe or stop a pipeline from leaking. This article will introduce the process of using the pressure plug in detail.

1. Preparation

There are some preparations that need to be made before a pressure plug can be performed.

1 Stability check

Before plugging with pressure, perform a stability check to ensure a quiet operating environment.

2. Determine the sealing position Determine the position of the pipe to be blocked and the location of the leakage point.

3. Select an appropriate plugging tool

Select the appropriate plugging tool. According to the pipe size, material and use conditions, select the appropriate expansion tape and stopper.

4. Prepare tools and materials

Obtain required tools and materials, such as writing tape, sealer, manual wrench, pressure gauge, and sealing materials.

2. Block the pipeline

1. Clean the pipe surface

Clean the surface of the pipe to ensure that the surface is clean and dust-free to ensure the sealing effect.

2. Adjust the expansion tape size

According to the size of the pipe and the size of the stopper, adjust the size of the expansion tape and wrap it around the stopper.

3. Place the stopper into the pipeline

Feed the resized occluder into the pipe until it reaches the occluder position.

4 Rotate the plug using a manual wrench

Use a manual wrench to rotate the stopper so that it is clamped against the inner wall of the pipe to ensure that the stopper is firmly fixed in the pipe.

5. Expansion tape

The tape is sent into the stopper and then installed in the pipe in an expanding manner until the tape in the pipe is filled.

6. Use a pressure gauge

Use a pressure gauge to detect and ensure that the pressure in the pipe does not exceed the larger capacity of the stopper and expansion belt.

7. Check the tightness of the pipe

After plugging, check the tightness of the pipe and test with a pressure gauge to ensure the plugging effect.

3. End the operation

After plugging is complete, perform several operations to ensure stable operation.

1. Recycle tools and materials

Recycle all tools and materials used for plugging and properly clean and store them for next use.

2. Clean the operation area

Clean the operation area to ensure that the operation area is clean and dust-free.

3. Evacuate the scene

Evacuate the site and properly dispose of used materials and waste.

In SUMMARY:

The above is the use process with pressure plugging, should pay attention to safety when using, according to the specific situation to choose the appropriate plugging method, and operate in accordance with the process. During operation, the sealing effect should be carefully checked and the pressure in the pipeline should not exceed the bearing capacity.
