ASA HV Radius 90° Elbows (Grooved Flanges)

ASA HV Radius 90° Elbows (Flat Flanges)

ASA HV Radius 90° Elbows (Flat Flanges): Smooth Vacuum Flow with Flat ASA Flange Sealing for HV Applications

ASA HV Radius 90° Elbows (Flat Flanges) by TFM are precision-engineered components designed to deliver seamless 90° directional transitions in high-vacuum (HV) systems using ASA-standard sealing interfaces. Manufactured from corrosion-resistant 304L stainless steel, these elbows combine vacuum reliability with flow-optimized geometry and long-term durability.

Featuring a radius bend, these elbows provide a gentle, low-turbulence path for vacuum or process gases, minimizing pressure drops and improving overall system efficiency. Both ends are fitted with rotatable flat ASA flanges, specifically designed to mate with grooved flanges containing o-rings, following the ASA sexed sealing standard.

Key Features of ASA HV Radius 90° Elbows (Flat Flanges):

  • Dual Flat ASA Flanges
    All ports are equipped with rotatable flat ASA flanges, allowing for secure, o-ring-based sealing when paired with grooved flange counterparts. Supports vacuum integrity down to 10⁻⁸ Torr.

  • 304L Stainless Steel Construction
    Provides high corrosion resistance, structural strength, and compatibility with a wide range of vacuum system chemicals and temperatures.

  • Smooth Radius Geometry
    Reduces flow resistance and improves conductance, making these elbows ideal for systems requiring minimal disturbance to vacuum flow.

  • Rotatable Flanges
    Enable precise alignment during installation, simplifying vacuum chamber layout and maintenance procedures.

  • Vacuum-Ready Performance
    Each ASA HV Radius 90° Elbow (Flat Flanges) is helium leak tested and cleaned to high-vacuum standards for dependable integration into sensitive systems.

  • Custom and Standard Sizes Available
    Offered in standard ASA flange diameters (e.g., 4″, 6″, 8″, 10″, 12″), with options for custom tube length, wall thickness, and bend radius upon request.

Applications:

  • Right-angle routing between grooved-flange ASA components

  • Smooth directional changes in forelines or process lines

  • Compact manifold designs with reduced gas turbulence

  • Modular vacuum infrastructure in R&D or semiconductor systems

  • Retrofit of elbow transitions in ASA-based high-vacuum assemblies

TFM also supplies matching ASA grooved flanges, FKM or Buna-N o-rings, bolt kits, and blank flanges to ensure full sealing compatibility and assembly efficiency.

In conclusion, ASA HV Radius 90° Elbows (Flat Flanges) offer vacuum engineers a reliable, low-profile solution for directing vacuum flow with precision and stability. Their flat flange configuration allows seamless mating with grooved interfaces across a broad range of ASA-standard systems.

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.
