What is AWWA C207 Class D flange?

AWWA C207 Class D flanges refer to a specific category of steel ring-type slip-on and blind flanges designed and manufactured in accordance with the American Water Works Association (AWWA) standards. These flanges are intended for use in waterworks applications, including potable water, wastewater, and other water-related systems.

Key characteristics of AWWA C207 Class D flanges include:

1. Pressure Rating: Class D flanges are designed for a working pressure up to 175 psi (pounds per square inch) or approximately 1.2 MPa (megapascal), depending on the operating temperature. The temperature range for this pressure rating typically extends up to 250°F (121°C).

2. Materials: Class D flanges are commonly constructed from various materials suitable for water-related applications, such as carbon steel, stainless steel, ductile iron, or other materials compliant with AWWA standards and suitable for handling water.

3. Dimensional Specifications: These flanges are available in sizes ranging from 4 inches to 144 inches in diameter. They conform to specific dimensional requirements outlined by AWWA C207 standards, ensuring compatibility and interchangeability in water supply systems.

4. Drilling Pattern: Class D flanges have a drilling pattern that aligns with the specifications detailed in the AWWA C207 standard, allowing for secure and standardized connections in waterworks applications.

AWWA C207 Class D flanges are utilized in various water supply and distribution systems, including municipal water treatment plants, potable water pipelines, wastewater treatment facilities, and other infrastructure projects where reliable and standardized connections are essential for the efficient operation of water-related systems.

It’s important to note that these flanges are designed specifically for waterworks applications and comply with AWWA standards to ensure durability, reliability, and compatibility within water supply networks.
