How does the spiral winding structure prevent the gasket from failing due to excessive mechanical stress?

Under high pressure conditions, the spiral winding structure can effectively prevent the gasket from failing due to excessive mechanical stress, mainly through the following aspects:

Elasticity and flexibility of the spiral structure:

The spiral winding design makes the gasket have high elasticity and flexibility, and can produce appropriate compression and deformation when subjected to mechanical stress.

The graphite filling layer has certain compressibility and recovery, and can change its shape under external pressure and absorb part of the mechanical stress, thereby avoiding the rupture or failure of the gasket.

Rigid support of the outer ring:

The 304 stainless steel outer ring provides the necessary rigid support to prevent the gasket from being over-compressed or deformed under high pressure. The outer ring helps to maintain the stability of the gasket shape, so that it still maintains good sealing performance under high pressure.
The support of the outer ring can effectively disperse the local stress applied to the gasket, avoiding the failure of the gasket due to concentrated pressure in certain areas.

Uniform stress distribution:

The spiral winding structure has a relatively uniform stress distribution characteristic. When high pressure acts on the gasket, the combination of the wound metal strip and the graphite material will cause stress to be transmitted in multiple directions, thereby avoiding local excessive concentration and reducing the risk of rupture caused by stress concentration.

Adaptability of graphite filling layer:

As a filling material, graphite has good compressibility under high pressure environment. It can produce appropriate compression and deformation under external pressure, fill the gap between the flange surface and the gasket, ensure uniform contact of the sealing surface, and avoid the decline of sealing performance.
The high temperature resistance and corrosion resistance of graphite enable the gasket to maintain good pressure resistance and sealing effect even under high pressure environment.

Long-term stability:

The spiral winding structure can not only effectively cope with mechanical stress under instantaneous high pressure, but also maintain stable sealing performance under long-term pressure. The combination of graphite layer and metal outer ring can resist the repeated action of high pressure and mechanical stress for a long time, ensuring that the gasket is not easy to fail.
Through the above design features, the spiral winding structure provides excellent mechanical stress resistance under high pressure conditions, ensuring the long-term stability and reliability of the sealing gasket.
