Sealing Gasket Types
Flanges and Gaskets
Today we will provide a brief introduction to metal C-ring and O-ring gaskets.
Metal C-ring and O-ring Gaskets
Metal C-ring and O-ring gaskets have become crucial solutions in industrial sealing due to their unique structure and elastic self-tightening sealing characteristics. They are widely used in high-pressure and complex environments such as petrochemical and nuclear power industries.
The C-ring and O-ring gaskets are named after their cross-sectional shapes, reflecting innovations in engineering sealing technology. A helical spring can be embedded inside, and the exterior can be coated, electroplated, or sprayed with soft sealing materials. When bolts apply load or radial compression, the sealing ring is subjected to axial or radial compressive force, generating pre-tightening sealing specific pressure to ensure reliable sealing performance.
In practical applications, these gaskets demonstrate significant advantages. As the medium pressure increases, the sealing ring expands radially or axially, forming self-tightening force that enhances sealing stress, achieving self-tightening sealing. This elastic self-tightening feature is particularly suitable for occasions with large pressure fluctuations, such as petrochemical equipment and nuclear power plant systems.
BMCRIN: Exhibits excellent compression resilience and sealing capability.
Precautions for Using Metal C-ring and O-ring Gaskets:
1、First, select appropriate materials and structural forms based on operating conditions.
2、Second, ensure correct pre-tightening force during installation – it should achieve the necessary sealing specific pressure without excessive compression.
3、Finally, regularly inspect the gasket condition and replace worn or aged components promptly.
With advancements in materials science and manufacturing technology, the performance of metal C-ring and O-ring gaskets continues to improve. The application of new alloy materials enhances their temperature and pressure resistance, while precision machining ensures dimensional accuracy and surface quality, enabling them to adapt to harsher working environments.
BMCORIN: O-type sealing ring suitable for valves and nuclear power.
Metal C-ring and O-ring gaskets excel in high-pressure complex environments due to their elastic self-tightening sealing characteristics. Through reasonable material selection, standardized installation, and regular maintenance, their long-term stable operation can be ensured, making them important choices in the field of industrial sealing.
