Vacuum flanges are used for scientific and industrial applications to allow various pieces of equipment to interact via physical connections and for vacuum maintenance, monitoring, and manipulation from outside a vacuum’s chamber.
What are CF flanges?
ConFlat (CF) fittings are flanges which utilize metal seals to attain vacuum conditions. The combination of a stainless-steel knife-edge flange and a copper gasket (OFHC) makes for a nearly impenetrable vacuum barrier. CF flanges use a series of bolts, unlike other vacuum seals that use clamps and elastomers.
Are KF and NW flanges the same?
NW (also known as KF & QF) NW Vacuum Hardware is known also as KF and QF. NW Vacuum Flanges and Fittings are quick release and are great in rough vacuum to high vacuum applications. NW Fittings are quick and easy to use and assemble into a vacuum system.
What is a KF fitting?
KF flanges are a sexless design made from 304 stainless. Also known as ISO, DIN, Pneurop, Quick Flange, Klein Flange, Dell Flange and Kwik-Flange. The seal is a rubber/ elastomeric o-ring mounted in a centering ring, which aligns the flanges and holds the o-ring in position.
What is ISO-KF?
The ISO-KF system is a family of small vacuum components up to 2” that include flanges, elbows, tees and crosses. The International Standards Organization (ISO) defines the interface dimensions, allowing the interchanging of components that conform to the standard’s dimensions.
What is KF clamp?
ISO-KF Vacuum Flange Components. ISO-KF Vacuum Flange Clamps.
How do you tighten a CF flange?
Apply a wrench to both the bolt head and the nut. Tighten by turning the nuts in small increments (1/2 turn or less) using the alternating pattern shown in the diagram, choosing a bolt across the flange from the last. Continue the incremental tightening of the nuts until the desired torque pressures have been achieved.
What is a KF clamp?
KF Clamp offered by us are used in rough to high vacuum installations. These clamps are designed in accordance of international standards, consists of two symmetrical flanges, a center ring to support and positioning “O”-ring, and a clamp which allows assembly without any tools.
What is an LF flange?
ISO – KF Flanges, LF Flanges This is the standard high vacuum sealing method used throughout the industrial and scientific vacuum communities. LF Style flanges have groves in the top that accommodate the use of Claw Clamps and bolts to tighten the flange to the centering ring , ultimately making the vacuum seal.
What are the different types of flanges?
Most commonly used flanges are weld neck flange, slip on flange, blind flange, socket weld flange, threaded flange and lap joint flange (RTJ Flange). This type of connection in a pipe flange allows for ease of disassembly and separation for repair and regular maintenance.
What is KF 25?
KF25 (NW25) Blank Flange Vacuum Fitting – Stainless Steel Cap – Stopper. These Blank Flange fittings follow ISO-KF standards. They are commonly used to build foreline vacuum plumbing and process systems. They are often called quick flange fittings because they are quick to assemble.
What is ISO KF?
What is Conflat UHV?
ConFlat® (CF) UHV Tees Fabricated from 304L stainless steel tubing and knife-edge CF flanges. Standard and reducer options available. ConFlat® (CF) UHV Crosses & Cubes
What kind of flanges does Conflat make?
ConFlat® (CF) UHV Flange Technical Notes We manufacture a comprehensive range of flanges and flanged components such as nipples, elbows, tees, and crosses in all standard vacuum flange systems. In addition, we supply a variety of hardware and components.
What are the best gaskets for conflat UHV flanges?
Annealed Copper Gaskets for ConFlat (CF) UHV Flanges Annealed Copper Gaskets are high purity, oxygen-free copper and require lower tightening torque to make leak tight seal. Used in UHV applications, more commonly for mounting fragile flanged components such as viewports. Annealed Nickel Gaskets for ConFlat (CF) UHV Flanges
