AWWA C207 Class B Ring Flanges – Reliable Low-Pressure Flange Solutions
The AWWA C207 Class B Ring Flange is designed specifically for low-pressure waterworks and utility piping systems, with a maximum pressure rating of 86 psi. It is manufactured in accordance with the American Water Works Association (AWWA) C207 standard and is suitable for use in light-duty municipal and industrial piping. These flanges are flat-faced, ring-type, and usually supplied undrilled or drilled to match ANSI B16.1 Class 125 specifications. Werner Flanges Inc. provides precision-engineered Class B flanges to meet diverse infrastructure needs.
Class B flanges are commonly used in utility services such as potable water lines, irrigation systems, and stormwater handling. Due to their lightweight construction and pressure limitations, they are ideal for non-critical or low-pressure flange connections in both municipal and industrial pipelines. Their design makes installation efficient and cost-effective for engineers working within conservative pressure ratings.
Werner Flanges Inc. supplies AWWA C207 Class B Ring Flanges in sizes ranging from 4” up to 144” in carbon steel and coated finishes such as black paint, red oxide, or hot-dip galvanizing. These flanges are offered with or without bolt holes and can be custom-drilled to suit specific pipe configurations. We maintain large inventories and quick dispatch capability to serve both domestic and international clients.
