Copper Alloy Flange Dimensions

Copper alloy flanges are essential components in piping systems where corrosion resistance, thermal conductivity, and antimicrobial properties are critical. Manufactured according to ASME B16.24 standards, these flanges are typically constructed from alloys including C83600 (leaded red brass), C922200 (leaded tin bronze), and C95200 (aluminum bronze), containing approximately 85-86% copper content.

Available in pressure classes ranging from 150 to 2500, copper alloy flanges offer the same bolt hole patterns and flange face dimensions as their steel counterparts specified in ASME B16.5, ensuring interchangeability in mixed-material systems. These flanges are commonly specified in marine applications, plumbing systems, HVAC installations, and chemical processing where copper's natural properties provide superior performance over carbon steel alternatives.

The comprehensive dimension tables below provide detailed specifications for threaded pipe flanges, blind flanges, and flanged fittings across all pressure classes. Each specification includes critical measurements such as outside diameter, bolt circle diameter, number and size of bolt holes, flange thickness, and raised face dimensions. Understanding these precise dimensions is crucial for proper system design, gasket selection, and bolt specification.

Whether you're designing a new piping system or replacing existing components, these standardized dimensions ensure compatibility and reliable performance. The following resources provide complete dimensional data organized by pressure class, making it easy to select the appropriate copper alloy flange for your specific application requirements.
