The sealing of Tandem Flange mainly depends on its unique structure and careful design. The following is a detailed explanation of the sealing of Tandem Flange:
1. Overview of Sealing Principle
The sealing of Tandem Flange is mainly achieved through the pressure between the sealing surfaces and the elastic deformation of the sealing material. In the flange connection, the flange and flange gasket are first placed at the connection part, and then the two flanges are tightly connected together with bolts. When the connection is completed, a sealing surface will be formed at the interface. By adjusting the tightening force of the bolts, the pressure between the sealing surfaces can be controlled to achieve the sealing effect.
2. Selection of Sealing Materials
The selection of sealing materials is crucial to the sealing of Tandem Flange. Commonly used sealing materials include rubber, asbestos, polytetrafluoroethylene, etc. These materials have strong elastic deformation and rebound capabilities, and can quickly return to their original state when subjected to external pressure, thereby ensuring the sealing effect. Different sealing materials are required for different media to ensure good sealing performance under various working conditions.
3. Pressure control between sealing surfaces
The pressure between sealing surfaces is determined by the size of the contact area between the flange and the flange gasket and the tightening force of the bolts. In order to ensure the sealing effect, the pressure between the sealing surfaces needs to be high enough to maintain the sealing effect under harsh conditions such as high temperature and high pressure. At the same time, in order to avoid damage to the gasket or flange due to excessive bolt tightening force, the tightening force of the bolts needs to be adjusted according to the specific situation.
4. Flatness of sealing surface
The flatness between the surfaces refers to the flatness of the flange and the flange gasket in the contact area, which directly affects the contact quality between the sealing surfaces. During the manufacturing and installation process, the flatness of the flange and the flange gasket needs to be strictly controlled to ensure that they can fit tightly to form an effective sealing surface.
In summary, the sealing performance of Tandem Flange depends on many factors such as sealing principle, selection of sealing materials, pressure control between sealing surfaces, and flatness of sealing surfaces. Through reasonable design, careful manufacturing and strict installation, it can be ensured that Tandem Flange can maintain good sealing performance under different working conditions, thereby effectively preventing the occurrence of leakage problems.
