We are a Manufacturer, Supplier, and Exporter of AWWA Flanges. AWWA Flanges are commonly utilized in waterworks, wastewater, slurry, plant piping, or other light-duty applications generally requiring pressures of but 300 psi. Pressure ratings for AWWA flanges range from the category B flange rated at 86 psi to Class F flanges, both rated at 300 psi.

The use of AWWA flange has long been accepted for concrete piping systems, and more recently with polyethylene piping, as a backup ring. When used with a low-pressure piping system, AWWA flange can frequently offer the user cost saving over commonly forged flange which is generally designed for higher pressure applications like oil, steam, chemical.

The American Water Work Association was founded on March 29th, 1881. They worked together to identify uniform requirements for the waterwork system. the primary ANSI/AWWA C207 steel pipe flange specification was officially adopted in 1955. The AWWA C207 specifications cover steel ring-type blind flanges and slip-on flanges.
