AWWA C207 Flanges Manufacturers

AWWA Flange refers to flanges manufactured according to the standards set by the American Water Works Association (AWWA), a key organization in the water utility industry. These flanges are specifically designed for use in water treatment, distribution systems, and wastewater management applications. The AWWA flanges are generally used to connect pipes, valves, and other fittings in water pipelines to ensure leak-free, secure joints that can withstand the pressure and environmental conditions of water systems.

AWWA flanges are typically made from materials such as ductile iron, carbon steel, or stainless steel, offering excellent resistance to corrosion and ensuring longevity in both potable and non-potable water systems. The most common types of AWWA flanges include ring flanges and slip-on flanges, with designs that ensure ease of installation, maintenance, and reliable performance in waterworks.

The AWWA standards, such as AWWA C207, define specifications for flange dimensions, pressure ratings, and material characteristics, ensuring uniformity and compatibility across different manufacturers and applications. These flanges are crucial for maintaining the integrity of water pipelines and ensuring the smooth flow of water in municipal and industrial water systems.
