  • Outer Diameter (OD): 6.00 inches

  • Flange Type: Standard ConFlat® (CF) flange, which ensures a secure, leak-tight seal, making it suitable for UHV and high-pressure applications.

  • Vacuum Rating: Designed for reliable performance in ultra-high vacuum systems, ensuring minimal outgassing and the maintenance of stable vacuum conditions.

  • Sealing Compatibility: Compatible with copper or metal seals to form an airtight, leak-proof connection.

  • Finish: Precision machined surfaces for smoothness and cleanliness, reducing the risk of contamination and enhancing long-term vacuum stability.

  • Configuration Options: Available in both rotatable and fixed configurations for flexible use in various vacuum system setups.

Applications:

  • Semiconductor Industry: Essential for UHV chambers used in semiconductor processing, including thin-film deposition, etching, and other processes where precise vacuum conditions are essential.

  • Scientific Research: Ideal for research applications requiring UHV conditions, such as materials science experiments, surface analysis, and particle physics research.

  • Aerospace and Space: Suitable for UHV systems used in space exploration and satellite technology, providing consistent performance in extreme conditions.

  • Vacuum Coating and Furnaces: Used in high-precision vacuum coating systems and vacuum furnaces where stable UHV conditions are crucial.

  • Industrial Vacuum Systems: Perfect for use in industries like optics, metallurgy, and electronics, where UHV systems are necessary for manufacturing and testing processes.

Advantages:

  • Durability and Strength: 316LN stainless steel construction offers exceptional durability, even in harsh vacuum conditions, ensuring long-term performance.

  • Leak-Proof Sealing: The ConFlat® design, combined with high-quality seals (copper or metal), ensures a tight, leak-free seal, critical for maintaining UHV conditions.

  • Precision Machining: The flanges are carefully machined to maintain flatness and smoothness, essential for high-performance vacuum sealing.

  • Flexibility: Available in both rotatable and fixed versions to accommodate different installation requirements.

  • Consistent Performance: Manufactured to maintain stable and reliable vacuum conditions over extended periods, ensuring minimal outgassing and optimal UHV system performance.

Manufacturing Process:

These DN100CF flanges are made through a cold-pressing and sintering process, followed by elastomer bonding to provide high-density, uniform structure and excellent durability. Each flange is cleaned thoroughly to meet stringent vacuum cleanliness standards and packaged carefully to protect them from environmental contaminants during shipping.

FAQ

Tube fittings are designed for tubes (measured by outside diameter and wall thickness) used in high-pressure and instrumentation applications, whereas pipe fittings are for pipes (identified by nominal pipe size) primarily used in fluid transport.

 

Common valve types include ball valves, gate valves, check valves, butterfly valves, and globe valves. Each serves a specific function—from quick shutoff (ball/gate valves) to flow regulation (globe valves).

 

  • For tubing, measure the outside diameter; for pipes, refer to the nominal pipe size (using conversion charts if needed). Always match the valve or fitting size to your pipe’s dimensions and flow requirements.

  • Frequently used thread types include NPT (National Pipe Tapered), BSP (British Standard Pipe), and UNC, along with slip-fit options that rely on compression or fusion rather than threads.

Interchangeability depends on manufacturer specifications and certification. Always verify compatibility via manufacturer guides or certified interchangeability charts.

 

  • A coupling is a short, straight fitting used to join two pipes or tubes. It provides a secure, leak-tight connection and can sometimes serve to extend or repair piping runs.

Consider valve type, pressure and temperature ratings, material compatibility with your fluid, actuation method (manual or automatic), and maintenance requirements.

 

  • Valves regulate flow by opening, closing, or partially obstructing the pathway. Their mechanisms (such as the rotation of a ball or the linear movement of a gate) determine the speed and precision of flow control.

  • A flange is a flat, circular component used to connect pipes, valves, or other equipment. Bolted together with gaskets, flanges provide a secure, leak-proof joint that facilitates both assembly and maintenance.

  • Manual valves require physical operation via handles or levers, whereas actuated valves use mechanisms—pneumatic, electric, or hydraulic—to open and close automatically or remotely.

  • Issues include leaks caused by improper installation, over-tightening, degraded seals, material incompatibility, and fatigue from repeated cycling. Regular inspection and proper installation practices help mitigate these problems.

Regular maintenance involves periodic inspections, cleaning or replacing worn seals, ensuring proper torque during installation, and adhering to manufacturer guidelines and local plumbing codes to preserve system integrity.
