Pressure sealing is a technique used to seal and seal a pipe or container. By applying pressure, the sealing material can effectively seal the pipe or container and prevent the leakage of the body or gas. This technology has been widely used in industry, petroleum, chemical industry, construction and other fields.

The principle of sealing with pressure is to use the properties of the sealing material by applying pressure to fill it into the pipe or container to the sealed mesh. The blocking material is usually a material with high plasticity, such as a colloidal substance, an expansive material or a special sealing tape. These materials can deform under pressure and fill gaps in pipes or containers to achieve sealing.

The key to sealing with pressure is to apply appropriate pressure. The pressure applied needs to be higher than the pressure inside the pipe or container to ensure that the plugging material can effectively fill the gap and maintain a stable sealing effect. In order to achieve this, the common method is to use specialized plugging devices, such as plugging capsules or plugging bombs, which are able to provide sufficient pressure to drive the plugging material.

The steps for sealing with pressure are as follows:

1. Preparation: Before sealing with pressure, clean and inspect the pipe or container to ensure that the surface is smooth, free of impurities and damage. At the same time, select the appropriate plugging materials and equipment, and prepare the necessary tools and protective measures.

2. Install plugging devices: Install plugging devices to the positions where pipes or containers are blocked as required. These devices usually include sealing capsules, sealing springs, etc., and the appropriate equipment can be selected according to the actual situation.

3. Apply pressure: Use specialized pressure equipment, such as a hydraulic pump or air source, to apply enough pressure to make the plugging material fill the gap in the pipeline or container. It should be noted that the pressure applied should be appropriate, too high or too low may affect the sealing effect.

4. Check the sealing effect After applying pressure, it is necessary to check the sealing effect. The effectiveness of the closure can be assessed by observing the leak point, using a leak detector, or performing a pressure test. If leakage or adverse conditions are found, it is necessary to adjust or re-plug in time.

To sum up, pressure plugging is a technique that applies pressure to seal and seal a pipe or container. It is a sophisticated work that requires comprehensive consideration of various factors, such as the selection of sealing materials, the installation of equipment and the control of pressure. Under the premise of correct operation, the effectiveness and stability of the sealing with pressure can be ensured.
