Hydraulically (Hydro) Formed Bellows – ISO Flanged (Braided Wall)

Fabrication of ISO Flanged Bellows for High Voltage Systems

TFM specializes in the production of ISO flanged formed bellows tailored for high voltage (HV) systems. These components are constructed using 300 series stainless steel flexible hoses in combination with 304L stainless steel ISO flanges. The ISO flange, often referred to as the Large ISO, is designed specifically for HV chamber ports and comes in two primary configurations: ISO-K, which utilizes clamp fasteners, and ISO-F, which employs nut and bolt fasteners.

Key Features of Hydroformed Bellows – ISO Flanged (Braided Wall)

  • Durability: Our flexible hoses are engineered to endure numerous flexing cycles, providing long-lasting performance without the risk of cracking.
  • Seam-Welded Design: The bellows are seam-welded to prevent virtual leaks commonly associated with lap-welded seams, ensuring a more reliable seal.
  • Flange Options: Available in the ISO-K style with clamp fasteners for ease of use.
  • Protection Features: The braided flexible hoses come with a protective sheath, safeguarding the convoluted hose against potential damage during operation.

TFM’s commitment to quality ensures that our products meet the rigorous demands of high voltage systems while providing enhanced durability and reliability.

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.
