Sealing with pressure is a common sealing technology, which is widely used in the pipeline system of petroleum, gas, chemical industry and so on. The specifications and models with pressure sealing mainly include pipeline size, material, working pressure, temperature range, installation mode and so on. Below I will explain these specifications and models in detail as well as the principles and applications behind them.

First, pipe size:

In the specifications with pressure sealing, the size of the pipeline should be defined first. Pipe size is usually described by internal diameter (DN) and wall thickness (WT), such as DN100, DN200, etc. The determination of pipe size is crucial to choosing the right plugging equipment, because different pipe sizes require different specifications of plugging equipment.

2. Materials:

The specifications with pressure sealing also include the materials used, such as stainless steel, carbon steel, cast iron, etc. The choice of material is determined according to the characteristics of the pipeline medium, operating temperature and pressure to ensure the corrosion resistance and strength of the plug in practical applications.

3. Working pressure:

Specifications with pressure plugging need to specify the working pressure that can be borne. Working pressure refers to the greater pressure that the plug can withstand during use, usually in the unit of megapascals (MPa) or pound force per square inch (psi). Different sizes and materials have different working pressure ranges, according to the actual needs to choose the appropriate specifications and models.

4. Temperature range:

Specifications with pressure sealing also need to consider the temperature range that can be tolerated. The temperature range refers to the temperature range in which the plugging appliance can work normally. It is usually expressed in degrees Celsius (° C) or degrees Fahrenheit (° F). The plugging appliance of different materials has different temperature resistance.

Five, installation mode:

The installation method of the plugging device must also be specified in the specifications and models with pressure plugging. The common installation methods are outer installation, part installation and ordering production. Different installation methods are applicable to different engineering scenarios and pipeline types. Selecting an appropriate installation method can improve the sealing effect and work efficiency.

The specifications and models with pressure sealing are the basis to ensure that the plugging equipment can work normally and achieve the expected effect. A reasonable selection of specifications and models can improve the stability and reliability of the plugging operation. In practical applications, it is also necessary to consider other factors such as the sealing performance of the sealing appliance, service life, etc., in order to comprehensively evaluate and select the appropriate sealing specifications with pressure models.
