AWWA C207 standard covers flanges with nominal sizes ranging from 4 inches to 144 inches (100 mm to 3,600 mm). These flanges are typically used in water supply systems, including potable water, wastewater, and water treatment plants.

The standard specifies various types of flanges, including slip-on flanges, blind flanges, threaded flanges, lap-joint flanges, and welding-neck flanges. Each flange type has specific dimensions, materials, and pressure ratings.

AWWA C207 also provides guidelines for gaskets and bolting used in conjunction with the flanges. The standard specifies the materials, dimensions, and installation requirements for gaskets to ensure leak-tight connections.
