AWWA (American Water Works Association) flanges are the polar opposite of API flanges, designed for lower pressure applications (300 psi or less) and can be found in a range of assemblies where the temperature is ambient and the media is non-corrosive. The majority of the time, this is used to convey well water and wastewater, but it can also be used for slurry and plant piping with low pressure needs. Viha Steel & Forging is the leading AWWA Flanges Manufacturer in India. We offer immediate delivery programs for standard sizes of Stainless steel AWWA Flanges and Carbon steel AWWA Flanges. AWWA Flanges are available with RTJ faces, raised, or flat, and are also available in Slip-on configurations.
