CF Bored Flange
CF internal welding flange refers to welding the CF standard flange to the interface of the vacuum pipe to achieve the connection and sealing of the pipe. This internal welding method can ensure the sealing and stability of the connection point, and is suitable for systems with high requirements for vacuum sealing performance, such as laboratory equipment, semiconductor manufacturing equipment, etc.
Therefore, CF internal welding flange is widely used in high vacuum systems in scientific research and industrial fields. It provides reliable sealing performance and stable pipeline connection, which meets the use requirements of various high-demand vacuum systems..

-High Vacuum Performance
Provides reliable high vacuum sealing, suitable for systems with high vacuum performance requirements.
Working in high temperature environment, its materials and welding process can withstand stress and pressure under high temperature conditions. This makes CF internal welding flanges have advantages in high temperature vacuum systems.
The design is relatively compact, which can effectively reduce the size and weight of the system, especially suitable for space-constrained environments.
It has high connection reliability and avoids the loosening and leakage problems that may exist in traditional bolted flanges.
The surface is smooth, dust and dirt are not easy to accumulate, and it is easier to clean and maintain.
