This section provides an overview for vacuum flanges as well as their applications and principles. Also, please take a look at the list of 13 vacuum flange manufacturers and their company rankings. Here are the top-ranked vacuum flange companies as of February, 2024: 1.Leybold GmbH, 2.Kurt J. Lesker Company, 3.Highlight Tech. Corporation.
A vacuum flange is a part used to cover a device to prevent gas leakage when a vacuum environment is desired inside a device.
Various standards for vacuum flanges, such as NW, KF, ICF, JIS, etc., are used according to the application.
First, NW and KF standards are used for piping and fittings in low to high-vacuum regions.
A device called a coupling is inserted to fasten a flange.
On the other hand, ICF and JIS standards use bolts to fasten a vacuum flange, which allows for less gas leakage and a higher vacuum level.
Vacuum flanges seal piping and fittings to maintain a vacuum environment inside specific equipment.
They are used in various applications, from academic research to manufacturing, and are frequently used with vacuum equipment.
Vacuum flanges are essential for the manufacturing of semiconductors, liquid crystals, and organic EL, which require a high vacuum environment.
Vacuum flanges are also required in academic research for various vacuum experiments (e.g., experiments with rarefied gases or solid surfaces, experiments in low-temperature environments, etc.).
The O-ring can be used repeatedly, thus saving cost, and can be used up to high vacuum environments.
It is vital to ensure that the flange edges are free of scratches and debris, as any damage can cause gas leakage.
After overlapping the flanges, gradually tighten the bolts together, so they are diagonal.
This tightens the flanges evenly and gradually. The vacuum is pulled after tightening all the way around to ensure no loosening.
Unlike JIS flanges, ICF flanges are fastened by inserting a copper gasket as a seal material.
The edge of the flange bites into the gasket and holds the vacuum flange.
This one has a better sealing property than the O-ring and is used to create an ultra-high vacuum.
The bolt fastening procedure is the same as for JIS flanges, but a uniform torque is necessary for each bolt using a torque wrench or similar tool.
NW/KF flanges have a ring (center ring) with an O-ring inserted between them, and unlike JIS/ICF flanges, the flanges are fastened using a coupling device.
They are easy to install without tools and can be used repeatedly.
