GOST 12820-80 Plate Flange is a flange product manufactured in accordance with Russian national standards.

1. Structural features

Flat structure

GOST 12820-80 Plate Flange has a relatively flat structural design. Unlike some flanges with complex structures such as protruding necks, this simple flat structure gives it certain advantages when the installation space is limited, such as in some compact pipeline layouts, it can be assembled more conveniently.

Disk design

The disk surface of the flange is flat and smooth, which is conducive to good contact with the sealing gasket, thereby ensuring the sealing effect. Bolt holes are evenly distributed on the disk surface, and the number, diameter and spacing of the bolt holes are strictly set in accordance with the GOST 12820-80 standard to ensure accurate matching with the corresponding bolts and other connectors.

2. Material and performance

Material selection

It can be made of a variety of materials, such as carbon steel, stainless steel, etc. Carbon steel plate flanges have high strength and good toughness, can withstand certain pressures, and have relatively low costs. They are suitable for some pipeline systems that are more cost-sensitive and do not require extremely high pressure. Stainless steel has excellent corrosion resistance and is widely used in industries with high corrosion resistance requirements such as chemical industry and food processing.

Pressure bearing capacity

According to the standard, it can work normally within a certain pressure range. In a well-designed pipeline system, it can stably withstand the pressure inside the pipeline and ensure the normal transportation of the medium in the pipeline.

3. Application field

Industrial pipeline system

In pipeline transportation in energy industries such as oil and natural gas, this plate flange can connect different pipeline sections to ensure the safe transmission of the medium. In the chemical industry, because it can use corrosion-resistant materials, it can well adapt to the transportation requirements of various chemical media.

Pipeline system in construction engineering

For example, water supply and drainage pipelines and heating pipelines in buildings, GOST 12820-80 Plate Flange can also play a role in connecting pipelines and ensuring the sealing of the system. It can cooperate with various pipeline fittings to build a complete pipeline network to meet the fluid transportation needs in buildings.
