The AWWA stands for the American Water Works Association is a technical, non-profit committee, that identifies and unifies major requirements for waterworks systems. Prominent users of the AWWA C207 Flanges Dimensions include Waterworks, Wastewater, slurry as well as plant piping. Since these flanges are used in low pressure piping systems, the awwa c207 class f flanges is a standard that proves to be an effective cost saving solution, as compared to either ANSI or ASME forged flanges. These awwa c207 flange dimensions have been designed for use in industries such as oil, steam, or chemical applications.

AWWA C207 Class D Hub Flange
AWWA C207 Flanges Standards
AWWA standards provide awwa c207 steel pipe flanges properties that are intended to be used for potable water only. For example, the ratings of AWWA flange is applicable only at atmospheric temperature. The AWWA standards cover flange classes that are lettered as B, D, E, F. Out of all these classes, the commonly used connection is class D. In contrast to ANSI, the nominal pipe sizes for awwa c207 class d blind flange ranges between 3 inches to about 144 inches. Unlike the ANSI standard that includes all types of flanges, the AWWA standard only encompasses the following types of flanges i.e. – ring flange, hub type flange, blind flange, and threaded iron flanges.
