AWWA stands for American Water Works Association, which is a nonprofit organization that provides standards, education, and advocacy for the water industry in the United States. AWWA has developed several standards for the water industry, including standards for flanges used in waterworks applications.

The AWWA C207 standard covers steel pipe flanges for waterworks service, and it includes two types of flanges: ring-type and hub-type. The standard covers flanges in sizes from 4 inches to 144 inches and in pressure classes ranging from 75 psi to 400 psi.

Ring-type flanges have a raised ring on their face, which provides a seating surface for the gasket. Hub-type flanges have a raised face on their outside diameter, which provides a seating surface for the gasket.

The AWWA C207 standard also includes material specifications for the flanges, which are typically made from carbon steel, stainless steel, or ductile iron. The standard specifies the chemical composition, mechanical properties, and testing requirements for the materials.

Overall, the AWWA C207 standard provides a comprehensive set of requirements for flanges used in waterworks applications, ensuring that they are designed and manufactured to meet the specific needs of the water industry.
