ANCORP offers CF weld flanges in two designs: fixed and rotatable. Fixed flanges are welded so that their bolt hole orientation is set. Rotatable flanges have a two piece design which facilitates bolt hole alignment during installation. In addition, bolt holes are specified as either tapped or through-hole ("clearance"). Standard CF weld flanges are manufactured from 304L stainless steel with sizes ranging from 1.33" to 16.25".
