Notes

  • Beveled flange fillers can be furnished. 4"-12" are available for 1⁄2" to 2 1⁄2" with 2" max. bevel. 14"-64" are available for 1⁄2" to 4" with 3 1⁄2" max. bevel. Although a wide range of beveled filler thicknesses is available, certain beveled filler thicknesses are limited by bolt clearance problems. Consult AMERICAN for all beveled filler applications.

Reducing flange fillers can be furnished for connecting pipe of two different diameters. In such cases, the fillers have two sets of bolt holes with one or both sets of holes tapped for studs.

CAUTION: When Installing Flanged Reducers:

The two flanges on most reducers have a different number of bolt holes, and all adjacent bolt holes do not straddle a centerline common to both flanges.

The centerline of the reducer is marked by notches on the circumference of each flange, and installation must be made in reference to this centerline. This would also be applicable with most reducing flanges and reducing flange fillers. Failure to assemble with the centerline at 12 o’clock will result in downstream equipment or bends not bolting correctly.
