Conflat (CF) UHV 4-Way Standard Crosses

ConFlat (CF) UHV 4-Way Standard Crosses: A Comprehensive Guide

ConFlat (CF) UHV 4-Way Standard Crosses are indispensable components in the design of ultra-high vacuum (UHV) systems, providing flexible, reliable, and leak-tight connections between different parts of a vacuum setup. At TFM, we specialize in the manufacture of CF UHV 4-Way Standard Crosses, offering precision-engineered components that meet the rigorous demands of both high and ultra-high vacuum environments. These crosses are crafted from 304L stainless steel tubing and equipped with knife-edge ConFlat (CF) flanges, a standard that has earned global recognition for its leak-tight performance in vacuum technology.

What are ConFlat (CF) UHV 4-Way Standard Crosses?

ConFlat (CF) UHV 4-Way Standard Crosses are vacuum fittings that allow multiple connections at different angles (typically 90 degrees) within a UHV system. They are specifically designed to facilitate the connection of components such as pumps, gauges, valves, and feedthroughs within a vacuum chamber. The 4-way configuration provides flexibility in routing pipes and instruments, making it a versatile solution for applications where space is constrained or where a complex configuration of components is needed.

Key Features of CF UHV 4-Way Standard Crosses

1. Precision Manufacturing with 304L Stainless Steel

The 304L stainless steel used in the construction of CF 4-Way Standard Crosses is known for its resistance to corrosion, strength, and excellent performance in high-vacuum environments. This material minimizes outgassing, which is essential for maintaining the vacuum integrity of the system over time.

2. Knife-Edge ConFlat Flanges

The heart of the CF cross is its knife-edge ConFlat flanges, which create an extremely tight, durable seal when mated with a compatible gasket. This ensures a vacuum-tight connection, even under challenging conditions. ConFlat flanges are the go-to solution for UHV systems because of their reliability and ease of use.

3. Rotatable Flanges (For Flexibility)

Many CF UHV 4-way standard crosses come with rotatable flanges, allowing for easy adjustment and alignment during installation. This feature ensures that the cross can be positioned and configured to meet the specific needs of your system layout without compromising performance.

4. Vibration-Resistant, Through-Hole Bolt Patterns

CF 4-Way Standard Crosses are designed with through-hole bolt patterns, which provide a secure, vibration-resistant connection. This design is particularly important in maintaining the vacuum integrity of the system under mechanical or thermal stress, preventing any loss of vacuum or system failures.

5. Versatile Mounting Options

The 4-way design of the cross allows for seamless integration with a variety of UHV components, including valves, gauges, and feedthroughs. This versatility makes them ideal for a wide range of industrial, research, and semiconductor applications.

Applications of ConFlat (CF) UHV 4-Way Standard Crosses

ConFlat (CF) UHV 4-Way Standard Crosses are used in a variety of high-tech and scientific industries where ultra-high vacuum is a necessity. These include:

  • Semiconductor Manufacturing: CF crosses are critical in vacuum chambers used for semiconductor fabrication processes, where clean, stable, and controlled environments are essential.

  • Material Science: UHV systems play a crucial role in research labs studying thin films, surface science, and other material properties.

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.
