Non-stop pressure plugging engineering is a common engineering technique to solve the leakage problem in the pipeline. The following will describe the project in detail in terms of definition, reasons, construction methods and equipment requirements.

I. Definition

Continuous pressure plugging engineering, referred to as engineering, refers to a kind of engineering technology that cuts on the pipeline, expands the leakage diameter, and seals on the leakage port when there is a leak in the pipeline. This technology can not only ensure the normal transmission of the pipeline, but also reduce the impact of leakage on the environment and equipment.

Ii. Reasons

During the use of the pipeline, there may be leakage due to various reasons (such as pipeline aging, temperature changes, pressure changes, etc.). These leaks can cause irreversible damage to the equipment and the environment. Therefore, the continuous pressure plugging project came into being.

Third, construction methods

1. Determine the leak point: Through detection and observation, determine the location and extent of the leak point.

2. Cutting pipes: Use cutting tools (such as cutting machines, flame cutters, etc.) to cut the leakage port and expand the leakage caliber.

3. Sealing the leak: According to the nature and extent of the leak, select the appropriate sealing material (such as sealant, leak repair glue, etc.), and fill it to the leak to ensure that the sealing is firm.

4. Restore the pipeline: repair the cut part as needed to ensure the integrity and sealing of the pipeline.

Fourth, equipment requirements

1. Cutting tools: including cutting machine, flame cutter, etc., used to cut pipes and expand leakage caliber.

2. Sealing materials: including sealant, leak sealant, etc., used to fill the leakage port to achieve the sealing effect.

3. Testing equipment: including thermometer, ultrasonic detector, etc., used to detect the location and extent of leakage points.

4. Repair equipment: including welding machine, bolt tightening device, etc., used to repair the cutting part of the pipeline and ensure the integrity of the pipeline.

It is concluded that the continuous pressure plugging project is an important maintenance technology, which can solve the leakage problem of the transmission pipeline timely and effectively. In the construction process, it is necessary to cut, block and repair according to the specific situation, and ensure the use of technical equipment and materials to achieve a stable and efficient repair effect.
