Metal octagonal gasket
Metal octagonal gasket is an important pipeline seal, widely used in high pressure and high temperature environments in the oil and gas industries. The following is a detailed overview of metal octagonal gaskets:
Definition and application areas:
The metal octagonal gasket is a solid metal gasket with an octagonal cross-section made of metal material, which has a radial self-tightening sealing effect. It is mainly used in oil and gas pipe flanges, pressure vessels, high-speed joints, high-temperature and high-pressure valve covers and other parts. Especially in situations where pressure and temperature fluctuate, the metal octagonal gasket can still maintain good sealing performance.
Structural features and materials:
The structures of metal octagonal gaskets mainly include R type, RX type and BX type. Among them, R type octagonal gaskets are suitable for flanges with standard grooves, while RX type and BX type are suitable for systems with higher pressure. Common materials include soft iron, SS304, SS316, carbon steel, SS321 and other alloy materials. These materials are not only resistant to high temperature and high pressure, but also have good corrosion resistance.
Parameter performance:
1. High temperature and high pressure resistance: suitable for high-pressure flanges, able to maintain good sealing performance under high temperature and high pressure environments.
2. Long-lasting and reliable sealing: even under pressure and temperature fluctuations, it can still maintain a reliable sealing effect.
3. Adapt to working conditions with pressure and temperature fluctuations: suitable for various complex working environments, including pipe flanges, tower tanks, pressure vessels, high-speed joints, high-temperature and high-pressure valve covers, etc. for high-temperature and high-pressure steam, gas, and solvents
4. Semi-self-tightening seal: When the connecting bolts are tightened, they are pressed against the upper and lower trapezoidal grooves by axial compression, resulting in plastic deformation, forming an annular sealing belt and establishing an initial seal. The gasket is more tightly pressed against the inclined surface of the trapezoidal groove, producing a self-tightening effect. However, the increase in medium pressure will also cause the flange and the connecting bolts to deform, resulting in relative separation between the sealing surfaces. Therefore, the ring gasket can be considered a semi-self-tightening seal.
5. Easy to process and reuse: The octagonal cross section is composed of straight lines and is easy to process. Although it is not easy to achieve complete sealing compared to the flange groove, it can be reused.
In summary, metal octagonal gaskets have become key sealing components in many high-pressure and high-temperature industrial applications due to their excellent high-temperature and high-pressure resistance and reliable sealing effect.
