What is the function of VG flange?

　　VG flange is an important component for connecting pipelines and equipment, usually used to connect pipelines, valves, pumps, instruments, and other equipment in pipeline systems. VG flanges are widely used in the industrial and construction fields, with their main function being to connect and seal different components in pipeline systems. In pipeline systems, VG flanges bear multiple important functions such as bearing pressure, ensuring sealing, transmitting force, shock absorption and vibration prevention, connecting pipelines and equipment, and are indispensable components in pipeline systems.

　　The functions of VG flange mainly include the following aspects:

　　1. Connect various equipment and components in the pipeline system: VG flanges can connect different components such as pipelines, valves, pumps, instruments, etc. together to form a complete pipeline system. VG flanges can not only connect pipes and equipment of the same material, but also connect pipes and equipment of different materials, achieving system flexibility and reliability.

　　2. Bearing internal and external pressures in pipeline systems: VG flanges play a role in bearing pressure in pipeline systems, capable of withstanding the pressure, fluid and medium impact forces transmitted in the pipeline, and transmitting them to other components in the pipeline system. At the same time, VG flanges can also withstand external forces such as lateral and axial forces, ensuring the stable operation of the pipeline system.

　　3. Ensure the sealing of the pipeline system: VG flanges use sealing components such as gaskets and sealing surfaces to achieve a sealed connection in the pipeline system, preventing medium leakage or external impurities from entering the pipeline system and ensuring the safe operation of the system. The sealing performance of VG flanges plays a crucial role in the normal operation of pipeline systems.

　　4. Transmission of force and rotational force: VG flanges can also transmit forces and torques in pipeline systems, such as axial and radial forces generated during the start, stop, and operation of pumps, which are transmitted to other components in the pipeline system through VG flanges to ensure the normal operation of the pipeline system.

　　5. Shock absorption and vibration prevention: In pipeline systems, fluid flow or equipment operation can generate vibration and impact. In order to reduce the impact of vibration and impact on pipeline systems and equipment, VG flanges can also play a role in shock absorption and vibration prevention, ensuring the stability and longevity of pipeline systems and equipment.

　　Overall, VG flanges play multiple important roles in pipeline systems, including connection, load-bearing, sealing, force transmission, and shock absorption. They are indispensable components in pipeline systems.
