Introduction
ISO100 HV Flanges are widely used connection components in high vacuum (HV) systems, offering a reliable and standardized solution for assembling vacuum pipelines and chambers. Designed according to ISO-K and ISO-F standards, these flanges provide excellent sealing performance, ease of installation, and compatibility across a wide range of vacuum equipment. They are essential in industries where stable vacuum environments are required, such as semiconductor manufacturing, coating systems, and scientific research.
Detailed Description
ISO100 HV Flanges correspond to a nominal diameter of 100 mm and are typically available in two main configurations: ISO-K (clamp-type) and ISO-F (bolt-type). ISO-K flanges are secured using claw clamps and centering rings with O-rings, allowing for quick assembly and disassembly. ISO-F flanges, on the other hand, are bolted connections designed for more permanent or rigid installations.
Manufactured from high-quality stainless steel such as 304 or 316L, ISO100 flanges offer excellent corrosion resistance, mechanical strength, and low outgassing properties. The sealing mechanism relies on elastomer O-rings (commonly Viton or Buna-N), which provide effective vacuum sealing down to approximately 10⁻⁸ mbar, making them suitable for high vacuum applications.
The precision-machined sealing surfaces ensure uniform compression of the O-ring, minimizing leakage risks and maintaining system integrity. ISO100 HV flanges are also compatible with a wide range of accessories, including valves, bellows, reducers, and adapters, making them highly versatile in complex vacuum system designs.
Applications
ISO100 HV Flanges are commonly used in:
- High vacuum (HV) systems and process lines
- Semiconductor fabrication and thin film deposition equipment (PVD, CVD)
- Vacuum furnaces and heat treatment systems
- Analytical instruments and laboratory vacuum setups
- Coating systems for optics and glass industries
- Leak detection and vacuum testing systems
