Sealing with pressure is a common engineering technology, which is used for sealing and sealing of pipes, containers and other equipment. It can effectively prevent the leakage of fluid, gas or solid particles and ensure the stable operation of the equipment. There are some important requirements and considerations to follow when using pressure plugging technology. I will describe these requirements in detail below.

First of all, it is very important to choose the right sealing material with pressure. Materials include rubber, plastic, metal, etc. When selecting materials, factors such as temperature, pressure and medium need to be considered to ensure that the corrosion resistance and pressure resistance of the material meet the requirements.

Secondly, before using pressure sealing, it is necessary to check and prepare the equipment to ensure that the surface of the equipment is smooth and there is no debris, oil or corrosion. For pipeline equipment, it is also necessary to check whether there is blockage, wear or corrosion inside the pipeline.

Next is the pre-treatment work before plugging. First, the equipment involved in the pressure plugging needs to be decompressed to reduce the internal pressure. Then, according to the characteristics of the equipment to choose the appropriate plugging method. The common sealing methods are mechanical sealing, liquid sealing and gas sealing, etc. Selecting the appropriate sealing method can improve the sealing effect.

When performing pressure plugging, the operating procedures must be strictly followed. Operators should wear personal protective equipment to ensure their own safety. In addition, you need to select the appropriate tools and equipment based on the device pressure and sealing material requirements. Pay attention to the operation skills during the operation to ensure the sealing effect and safe operation.

After plugging is complete, check and verify. The sealing effect can be tested by pressure test, sealing test and other methods. If the test result meets the requirements, proceed with subsequent operations. If the test result fails, plug and repair the device again.

Finally, the equipment with a pressure plug needs to be maintained and maintained. Check and maintain the equipment regularly according to the requirements of the equipment to ensure the normal operation of the equipment. If the sealing material is aging, damaged, or invalid, replace it in time.

In short, pressure plugging is an important engineering technology, the use of very strict selection of materials, adequate inspection and preparation, strict compliance with operating procedures, effective plugging and testing, as well as regular maintenance and maintenance of equipment, are the key to ensure the effect of pressure plugging and stable operation of equipment.
