Product Description

Vacuum Yigou provides KF flange components. KF is a quick installation and disassembly connection used in vacuum systems. It consists of the following components: two symmetrically distributed KF flanges, O-Ring, centering bracket, and clamp. Without the need for other tools, simply twist the disc-shaped nut by hand to loosen or tighten the connection.

Assembly Method and Steps

Quality Assurance

① Strict material selection

Choose high-quality Baosteel materials for processing to ensure reliable material quality.

② Integrated flange processing and forming

All components have a bright and smooth surface, with no burrs or burrs on the surface,

R1.5mm rounded corner

Fit dimension tolerance range: ± 20~50 μ M,

Surface roughness range: 0.8~1.6 μ M.

③ Welding component leakage detection

Vacuum welded components will be tested for leakage rate values ≤ 1E-11 pa. m3/s using a helium mass spectrometer leak detector.

④ Product cleaning and surface treatment

Vacuum products have undergone ultrasonic cleaning and electrolytic polishing of welded parts.

⑤ Baking and degassing

All components undergo a baking and degassing process, reducing the time customers need to obtain the desired vacuum degree and ensuring quality.

⑥ The product has interchangeability characteristics

The ultra-high vacuum components adopt both metric and British standards, and can be used in conjunction with domestic and foreign instruments. The products have the characteristic of interchangeability.

⑦ Product vacuum packaging

After vacuum degassing, all vacuum products are vacuum packaged.
