Table 2 of AWWA C207-18 provides specifications for Class B ring flanges. AWWA C207-18 is a standard published by the American Water Works Association (AWWA) that outlines the dimensions and tolerances for steel pipe flanges used in waterworks systems.
Class B ring flanges are designed for use with steel pipe for services with pressures up to 86 psi (595 kPa) and are typically used in water and wastewater applications. These flanges are produced in a range of sizes to accommodate different pipe diameters.
Table 2 of AWWA C207-18 for Class B ring flanges specifies various dimensions such as bolt circle diameter, number of bolt holes, bolt hole diameter, flange thickness, hub length, and facing dimensions. These specifications ensure that the flanges are manufactured to the required standards and guarantee proper alignment and sealing when connected to piping systems.
Class B ring flanges are typically manufactured from carbon steel or stainless steel and are built to withstand the operating conditions and pressure requirements of water distribution systems. The flanges are designed to provide a reliable and leak-free connection between pipes, valves, and fittings in waterworks applications.
In summary, Class B ring flanges as specified in Table 2 of AWWA C207-18 are essential components in water distribution systems, providing a strong and secure connection for piping infrastructure in water and wastewater treatment facilities.
