The CF (ConFlat) flange are most widely used in high vacuum and Ultra high vacuum (UHV) applications. The seal mechanism in this flanges is a knife-edge that is machined below the flange's flat surface and soft metal gasket is used to seal two flanges, as the bolts of a flange-pair are tightened, the knife-edges make annular grooves on each side of a soft metal gasket. The extruded metal fills all the machining marks and surface defects in the flange, yielding a leak-tight seal.Start a Work With Us
The CF seal operates from 103 mbar to < 1.3 x 10-13 mbar, and within the temperature range -196° C to 450° C and it depends on the soft metal gasket used to seal the component. CF bored flange dimension is maintained as per international standards. These bored flanges are machined using stainless steel 304 or 316L material.
ISO and KF bored flanges are used to weld in the vacuum line at the pipe end or in between the pipe depending on the requirement of end connection. ISO and KF bored flange dimension is maintained as per international standards.Length of bored flange is made as per customer requirement. These bored flanges are machined using stainless steel 304 or 316L material.Start a Work With Us
