Due to the material of the gasket, CF series flanges have excellent performance in high sealing effect and low leakage rate. When assembling the CF flange connection, press the copper gasket into the blade edge to simultaneously press the sealing material axially and radially outward on the flange. The materials are enclosed and cannot flow even at high baking temperatures. They can be easily separated using special tools or screwdrivers.

Simultaneously provide rotatable or fixed versions of flanges with through holes and self tapping bolt holes. Flanges with metric threaded holes or without threaded holes are of the same type of product. UNC or UNF standard holes, as well as threaded holes of other standards, can be customized according to requirements.

install

1. The CF flange connection consists of two identical flanges with flat washers made of OFHC copper, bolts, and nuts. Due to the application being in an ultra-high voltage environment, preparation work before installation is crucial. Surface cleaning can ensure the lowest possible gas release and leakage rates.

2. Using clean lint free gloves, place the pre cleaned OFHC copper gasket against the blade seal, preferably the flange that is most likely to secure and support the gasket from falling off. After the gasket is in place, match the flange with the required bolt direction; If the flange is equipped with a leak test slot, they should be aligned.

3. After aligning the flanges, insert bolts of appropriate size and tighten them by hand. Repeat this process using the remaining bolts. After tightening all bolts by hand, use two enclosed box wrenches to support the bolts and tighten the nuts. (The washer is used on the nut side)

CF flanges are suitable for applications in high-definition clean environments, ultra-high vacuum conditions, high temperatures, or hazardous materials.
