About anchor and filler flanges

Anchor flanges are designed to be embedded in concrete or structural walls to anchor the pipeline against axial movement, thrust and pull-out under operating pressure. Filler flanges make up small spaces between two flanges where a spool is not possible.

Anchor flanges (AF) are ductile iron; filler flanges (FF) are cast iron. Both are on SIGMA's Import Fabricator Products price list, with the threaded flanges and threaded MJ bell adapters.

Filler flanges come in four thicknesses: 1-1/4, 2-1/4, 3-1/4 and 4-1/4 in.

The April 2014 catalog has the dimensions: A, B and C for anchor flanges up to 48 in., and OD for filler flanges up to 12 in.
