Cf flange dimensions pdf. An ultra high vacuum pressure seal with proper bake-out (450°C) can be achieved down to 10-13 Download the latest version of our Wood Construction Connectors catalog that includes product information and applicable specification and installation instructions for over 3,000 connectors. EGMO CF FLANGES CF FLANGES General: EGMO CF type flanges is semiconductor industry standard for use down to UHV pressures. Features Suitable for UHV or high vacuum. preferred of specified Comparing KF, ISO, CF, ASA and JIS flanges by Ken Harrison, President There are numerous flanges in the world for all types of applications such as steam or liquids, but vacuum flanges have their own unique designs and designations. 33” to 16. When the gasket is compressed with the required torque (see following pages) between the knife edges of the CF flanges, its material flows to fill surface blemishes. Assemblies are usable up to 10-13 Torr. AdvanTorr offers Conflat flanges in a wide range of sizes from 1. Please find further technical details in the introductions of the subsections. All CF flanges are compatible with other manufacturers' standards and are available in SS304L material as standard, with an option for high-grade SS 316LN ESR. CF test assemblies The test assemblies were made by assembling two blank CF flanges with a copper gasket (from Lesker) and, when available, aluminum gaskets (from Lesker). Non-Rotatable1 — Blank CF Flange / 450°C / UHV to 1x10-10 Torr A B Bolt Holes C Flange Bolt Flange Flange OD Circle Quantity Diameter Thickness CF Conflat flanges (CF) are used for ultra- high vacuum pressure applications. Our flanges comply with the following standards: Rotatable and non-rotatable geometries OFE copper or optional Viton® elastomer gaskets Tapped or clearance bolt holes Compatible with other manufacturers' Conflat® knife-edge flanges Introduction technical document fir t edition 3669:1986), edition (ISO 3669:2017) defined two of “bakeable” significant — as a preferred series, the — a secondary corresponding main dimensions of which ensure compatibility with already standardized ISO 1609); This document specifies to flanges in common use. The CF flange (originally called ConFlat) is a sexless design where both flanges are identical. The flange provides an economical way of interfacing stainless steel vacuum fittings and components from 11/3 to 161/2 inches OD for 1/4 to 14 inch tube. Vacuum flanges are unique because they need to seal better than nearly every other flange. Conflat flanges (CF) are used for ultra- high vacuum pressure applications. Maximum temperature for sustained use is 400°C. In addition please add the size and the number of required bolts and the necessary copper gasket for dimensions from DN250. Each vacuum seal is made by . Please add the auxiliary dimensions (DN25, DN50, DN75, DN125) in case of requests and offers of CF flanges and components. The flanges were tightened using the cross flange pattern recommended in the MDC catalog until the flanges were visibly close to “metal to metal”. The selection of the most suitable system depends on the respective application. These fittings use a gasket and CF knife-edge flange. Tighten bolts gradually in 1/4 to 1/2 turn increments, as shown in crisscross star-pattern until specified bolt-torque is reached. CF FLANGES AND FITTINGS CF Flanges general specification. Flange, Gasket and Tube Dimensions Schematic drawings and dimensions of suitable flanges, gaskets and flanges with tube sockets. • The actual nominal diameter of DN40 is 35mm and that of DN160 is 150mm.

Schematic drawings and dimensions of suitable flanges, gaskets and flanges with tube sockets. 5” in both rotatable and non-rotatable versions. Flange systems (KF, ISO, CF) Three different flange systems or standards are basically used in vacuum technology. Flange dimensions are per ASTM standard for Knife-Edge seal flanges. CF flanges dimensions Adixen CF flanges and fittings are compatible with other Conflat® style flanges used by all other suppliers of the vacuum industry (Fig. Max. Seal made by stainless steel knife edge into copper or Viton® gasket. Typical flange materials are austenitic stainless steel types 304L, 316L, 316LN, and surface hardened aluminum (made from a weldable Al alloy). Protect flange seal surface (knife-edge) from damage.
