Bolt Hole Patterns and Compatibility Between AWWA Flange Classes
In the design and installation of AWWA flanges, pressure rating is an important factor, but equal attention must be given to the bolt pattern. The way a flange is drilled determines not only how it is fastened but also whether it is compatible with other flanges or not. If the drilling does not match, the […]
What Is the Pressure Rating of AWWA Flanges?
Pressure rating is one of the most critical specifications of AWWA flanges for a waterworks or industrial pipeline system. A flange’s pressure class determines its ability to safely withstand internal system pressures over time without failure. The American Water Works Association (AWWA) provides detailed standards (AWWA C207 and AWWA C228) that define these classes, which […]
What Are AWWA Flanges? A Guide for Waterworks Projects
Share: More Posts What Are AWWA Flanges? An AWWA flange is a type of pipe flange designed for waterworks service. It follows standards developed by the American Water Works Association and is specifically intended for low-pressure water applications. AWWA flanges are governed by standards such as C207 and C228, which guide the design, manufacturing, and […]
