How is the sealing of Hydraulic Flange Fittings achieved to ensure effective prevention of oil leakage and system leakage?

In Hydraulic Flange Fittings, gaskets are the core components for achieving sealing. Depending on the working conditions, gaskets of different materials and shapes can be selected, such as rubber, metal or composite gaskets. These gaskets have good sealing performance and are resistant to high pressure and high temperature. Through the preload of the bolts, sufficient pressure is generated between the gasket and the flange sealing surface. This pressure causes local plastic deformation on the gasket surface, while maintaining elastic deformation as a whole to fill the microscopic unevenness of the flange sealing surface, thereby forming an effective sealing surface.
The roughness of the flange sealing surface has an important influence on the sealing performance. Usually, the sealing surface is precision machined to ensure that its roughness meets the design requirements, thereby reducing the possibility of leakage. Some Hydraulic Flange Fittings use sealing surfaces with special shapes, such as conical sealing surfaces. This design can increase the contact area of ​​the sealing surface and improve the sealing effect.
In Hydraulic Flange Fittings, seals such as O-rings are often used to enhance the sealing performance. These seals have good elasticity and sealing properties, and can maintain a stable sealing effect under high pressure environments. The correct installation of seals is also a key factor in ensuring sealing performance. During the installation process, it is necessary to ensure that the seals are not damaged and the installation position is accurate to ensure that they can fully play their sealing role.
The sealing structure of Hydraulic Flange Fittings is usually optimized to ensure good sealing performance under various working conditions. For example, the sealing effect is improved by increasing the number of sealing surfaces and adopting multiple sealing structures. In addition to gaskets, the material selection of components such as flanges and bolts also has an important influence on the sealing performance. Usually, these components are made of materials with good mechanical properties and corrosion resistance to ensure their stability and durability under high pressure and high temperature environments.
The sealing performance of Hydraulic Flange Fittings is achieved through a variety of mechanisms such as the synergy of flanges and gaskets, the design of sealing surfaces, the selection of seals, and the optimization of sealing structures. These measures jointly ensure the stable sealing performance of Hydraulic Flange Fittings under high pressure and high temperature environments, thereby effectively preventing oil leakage and system leakage.
