Models with pressure plug include SMZD-2. For more information, it is recommended to consult the relevant product or technical person.

Pressure plugging is a common pipe repair method that can be used to plug the pipe without stopping the flow of fluid. This method is often used to repair pipe leaks or replace pipe parts.

The principle of sealing with pressure is to use special sealing materials and tools to form a new sealing structure inside the pipeline to prevent the leakage of fluid. According to different application scenarios and requirements, different methods and technologies can be used for sealing with pressure.

One of the commonly used pressure sealing methods is the mechanical sealing method, which is divided into support, expansion, clamping and other sub-categories. The

Another commonly used sealing method with pressure is the welding sealing method, which has a relatively good effect, but the space required to provide is relatively large, and it is not applicable if it is an underground pipeline.

In addition, there are other sealing methods with pressure, such as adjustment plugging method, packing method, wedge plugging method, etc. These methods can be used to plug the pipeline in the case of continuous flow, but the appropriate method needs to be selected according to the specific situation.

When performing a pressure plug, it is necessary to pay attention to the stable operation and skill level. Improper operation may result in pipe damage or personal injury. Therefore, it is recommended that you consult the technical personnel or the manufacturer for technical support and guidance when performing sealing with pressure.
