Component Specifications

Definition
A precision-engineered flange component designed specifically for vacuum gauge installation, featuring standardized dimensions and sealing surfaces to ensure leak-tight connections in vacuum systems. It serves as the interface between the vacuum gauge sensor and the vacuum chamber or piping system, maintaining system integrity under varying pressure conditions from atmospheric to ultra-high vacuum levels.
Working Principle
The flange connection port operates by providing a flat, machined sealing surface that mates with a corresponding flange on the vacuum system. When compressed with appropriate fasteners and sealing elements (such as O-rings or metal gaskets), it creates a vacuum-tight seal that prevents air ingress and maintains the required vacuum level for accurate pressure measurement.
Materials
Stainless steel (typically 304 or 316 grade), aluminum alloys (for lightweight applications), or specialized vacuum-compatible materials with low outgassing properties. Surface finish: Ra ≤ 0.8 μm for optimal sealing.
Technical Parameters
  • Leak Rate < 1×10^-9 mbar·L/s
  • Port Size DN 16 to DN 160
  • Flange Type KF, ISO, CF, or ANSI
  • Sealing Method O-ring, metal gasket, or elastomer
  • Surface Finish Ra 0.4-0.8 μm
  • Pressure Rating 10^-9 to 10^3 mbar
  • Temperature Range -20°C to 150°C
Standards
ISO 2861, DIN 28403, ISO 1609

Frequently Asked Questions

What are the main types of flange connections for vacuum gauges?

The main types are KF (Quick Flange), ISO (International Standard), CF (ConFlat), and ANSI flanges, each designed for specific pressure ranges and applications.

How do I ensure a proper seal on a vacuum gauge flange?

Use the correct gasket material (elastomer O-rings for medium vacuum, metal gaskets for high/ultra-high vacuum), ensure clean sealing surfaces, apply proper torque to fasteners in a cross pattern, and verify with leak testing.

Can different flange types be interconnected?

Yes, using appropriate adapters, but this may affect system performance. It's best to maintain consistent flange types throughout the vacuum system for optimal reliability.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
