AWWA C207-94 Class B hub flanges are a specific type of flange designed for use in water supply systems. AWWA C207-94 is a standard published by the American Water Works Association (AWWA) that sets the guidelines for steel pipe flanges used in waterworks systems.
Class B hub flanges are typically used in water distribution systems with operating pressures up to 86 psi (595 kPa). These flanges are commonly used in water treatment plants, wastewater facilities, and municipal water supply networks.
In AWWA C207-94, Class B hub flanges are classified based on the thickness of the flange and the pressure rating required for the application. The standard specifies various dimensions, such as flange diameter, bolt hole diameter, bolt circle diameter, hub dimensions, facing dimensions, and thickness specifications.
Class B hub flanges are typically manufactured from materials such as carbon steel or stainless steel to ensure durability and corrosion resistance in water applications. These flanges feature a raised hub in the center to provide additional strength and support when connecting to pipes or valves.
Overall, AWWA C207-94 Class B hub flanges play a critical role in water supply systems, providing a reliable and secure connection between piping components. These flanges are designed to meet the stringent requirements of waterworks applications and ensure the safe and efficient operation of water distribution infrastructure.
