Ebara CF flanges are compatible with other Conflat style flanges and are available in sizes from 1-1/3 to 16-1/2 inch OD for 1/4 to 14 inch tube diameters. Flanges 41/2 inch OD and smaller are made from 304 electroslag remelt (ESR) bar stock. ESR is a refining process that produces stainless steel with higher purity, fewer inclusions and more uniform grain structure to eliminate microscopic leak paths.
Ebara's ASA flanges are manufactured from specially treated 304 stainless steel. These flanges mate with standard 150 lb. ASA flanges or 150 ANSI flanges. They are available from stock for standard tube sizes from 2 to 12 inches. Larger sizes are available upon request.
