Product Description
All dimensions are in inches.
These flanges will be furnished with a 1/16" raised face unless otherwise specified.
EO Flanges can provide ANSI B16.5 Class 150 Plate Flanges, which Outside Diameter from 3.50 to 32.00 in, Raised Face Diameter from 1.38 to 27.25 in, Bore from 0.88 to 24.25 in, etc. The advantages of this method are obvious: the absence of cracks, voids in the metal, improved mechanical properties and better weld ability.
