ISO400 HV Flanges

TFM offers ISO400 HV Flanges, precision-crafted to meet the demanding requirements of high-vacuum (HV) chamber ports. These Large ISO flanges provide robust, reliable sealing solutions for advanced vacuum systems.

ISO400 Flange Styles:

  • ISO-K: Features clamp fasteners for efficient assembly and maintenance.
  • ISO-F: Secured with nut and bolt fasteners for a solid, dependable connection.

Compatibility for Mixed Connections:

ISO400 HV Flanges support versatile system setups, allowing seamless joints between ISO-K and ISO-F styles using a range of bolt and clamp options.

Design and Seal Highlights:

  • Each flange face is counter-bored or grooved to hold a metal centering ring with an elastomeric o-ring.
  • The centering ring ensures precise alignment of flanges while maintaining secure o-ring positioning for consistent, leak-free sealing.

Operational Parameters:

  • Temperature Range: ~0°C to 120–180°C, depending on the properties of the o-ring.
  • Pressure Range: From atmosphere to ~10⁻⁸ torr or mbar.

TFM’s ISO400 HV Flanges are engineered for exceptional durability and performance in demanding vacuum environments. Contact us for standard options or to customize a solution that suits your specific requirements!

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.
