AWWA C207-2007 defines forged steel plate flanges specifically for waterworks service. These flanges are designed for low-pressure applications, such as potable water, wastewater, and slurry piping. Unlike ASME high-pressure standards, AWWA C207 focuses on cost-effective, large-diameter solutions for plant piping. Typically manufactured from hot-rolled carbon steel, these plate flanges (Class B, D, or E) are slipped over the pipe and fillet welded, ensuring a reliable seal for municipal infrastructure.
