ISO160 HV Flanges

TFM offers ISO160 HV Flanges, specifically designed for high-vacuum (HV) systems. Known as Large ISO flanges, these components are ideal for HV chamber ports and provide robust and precise sealing solutions.

ISO160 Flange Styles:

  • ISO-K: Features clamp fasteners for quick assembly.
  • ISO-F: Utilizes nut and bolt fasteners for a strong and secure connection.

Mixed Connection Compatibility:

With various bolt and clamp options, ISO160 flanges can seamlessly connect mixed ISO-K and ISO-F components, ensuring system flexibility.

Key Design Features:

  • Counter-bored or grooved flange faces to hold metal centering rings with elastomeric o-rings.
  • ISO centering rings align flanges while securely retaining the o-ring for consistent sealing performance.

Application Range:

  • Temperature: ~0°C to 120–180°C (limited by the o-ring properties).
  • Pressure: From atmosphere to ~10⁻⁸ torr or mbar.

TFM’s ISO160 HV Flanges are engineered for reliability, durability, and seamless integration in vacuum systems. Contact us for standard or custom solutions tailored to your specific needs!

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.
