The pressure sealing technique is a kind of sealing method which is often used in the occasions that need to be sealed, such as pipeline, wellhead or container. It effectively stops the flow of liquid or gas by applying pressure to place the blocking object (such as the blocking ball, the blocking plug, etc.) in the position where it needs to be blocked. This paper will introduce the principle, application field, advantages and price of sealing with pressure in detail.

Principle of sealing with pressure:

Pressure plugging is the use of a plugging ball or plugging device, by applying pressure to place it in the position that needs to be blocked, to form a reliable blocking barrier to prevent the flow of liquid or gas. It typically packages the following steps:

1. Preparation: Select the appropriate sealing ball or sealing plug according to the actual needs, and aerate or fill the liquid to make it reach the required size and sealing performance.

2. Positioning: Place the sealing ball or plug in the position that needs to be sealed, and ensure that it can completely cover and seal the target area.

3. Apply pressure: By using a specific pressure pump or equipment, apply enough pressure to compress the sealing ball or plug and ensure that it can withstand the required sealing pressure.

4. Detection: After adding pressure, use relevant detection equipment or methods to check whether there is leakage or other problems at the sealing position, and ensure that the sealing effect meets the requirements.

Application field of sealing with pressure:

Pressure sealing technology is widely used in the oil, gas, chemical, water treatment and other industries in the pipeline, wellhead or container sealing needs. Specific application areas include:

1. Pipeline repair and maintenance: In the process of pipeline repair or maintenance, pressure plugging can temporarily plug the pipeline to ensure stable operation and equipment integrity.

2. Leakage prevention and control: When the pipeline or container leaks, the pressure sealing can quickly plug the leak point and prevent further leakage of liquid or gas.

3. Construction and testing: In the construction process of the new pipeline system, pressure sealing can be used to test the sealing performance of the pipeline to ensure that it meets the requirements of the specification.

4. Pipeline isolation: With pressure sealing, the pipeline or container can be separated into multiple independent parts for maintenance, cleaning, equipment replacement and other operations.

Advantages of sealing with pressure:

Pressure plugging technology has the following advantages:

1. Fast sealing: Sealing with pressure can quickly and effectively seal the pipeline or container, reducing the loss caused by leakage or flow.

2. Flexibility: With pressure plugging can be selected according to the actual needs of different sealing balls or plugging, and adapt to different sizes and shapes of pipelines or containers.

3. Reusable: The sealing ball or plugging can be used back and forth to reduce costs and improve efficiency.

4. Stable and reliable: the rigorously tested and verified pressure sealing system has good sealing performance to ensure stable operation and equipment integrity.

Price with pressure plug:

The price of sealing with pressure is affected by a number of factors, including the sealing ball or plugging material, size, performance requirements, and the number of orders. In general, the price of sealing with pressure is between hundreds and thousands of dollars, and the specific price needs to be detailed and negotiated according to actual demand.

In SUMMARY:

Pressure plugging is a commonly used plugging technique that effectively stops the flow of liquid or gas by applying pressure to place the plugging object in the position where it needs to be plugged. It is widely used in the oil, gas, chemical, water treatment and other industries in the pipeline, wellhead or container sealing needs. Sealing with pressure has the advantages of fast sealing, flexibility, repeatability, stability and reliability. In terms of price, specific negotiations and quotations should be made according to actual needs.
