CF FLANGE SERIES

CF flanges are available with tapped or untapped holes. Tapped flanges are available in UNCUNf or metric threads. Tapped tlanges have through holes, so bolts may protrude slightly from the back of the flange when fastened to an untapped flange. Untapped Cf flanges can be fastened to each other with stainless steel bolts and hex nuts or plate nuts. Plate nuts center themselves over two adjacent holes and can be held in place with one finger while the bolts are tightened. They are avallable for most flange sizes from 1 1/3 to 10 inch (33.96-254mm) ODs. As an alternative to hex head bolts, 12-point bolts are available for CF flanges from 2 3/4 to 10 inch (33.96 to 354mm) ODs. Silver plated bolts eliminate the need for anti-seize compoundin clean room environments.

 

ASSEMBLY INSTRUCTIONS FOR CF FLANGES

1. Apply a small amount of high temperature anti-seize compound to the bolt threads

2. Check that both flange surfaces are clean and sealing edges are free from nicks and scratches.

3. Using clean, lint free gloves, unpack gasket.

4. Place gasket in the knife edge counterbore of nonrotatable flange.

5.Align the mating hole pattern and leak test grooves.

6. Install the proper bolts and tighten hand tight. Check to see that the flange faces are parallel.

7. Tighten the bolts 1/4 to 1/2 turns using a star pattern until the flange faces are metal to metal.

8. Torque the fasteners to the listed value using the same pattern.

 

* U.S. manufacturers of CF flanges name them according to their outer diameter measured in inches i.e. a CF600 flange has an outer diameter of approximately 6 inches.

* European identification for these flanges is expressed in a variety of ways; the flange outer diameter is measured in millimeters or the flange inner diameter counterbore (the area machined to accept tubing for welding)is measured in. millimeters or the inner diameter of the largest through bore is measured in millimeters. Measurements are rounded to the nearest millimeter for naming purposes.

* U.S. and Metric CF flanges are compatible. The only difference in design is that metric flanges have a metric bolt thread machined into tapped bolt holes. QiMing can provide both metric tapped flanges on request.
