Flanges you select for your piping system must match the pipe material, size, pressure class, facing type, and service conditions to ensure mechanical integrity and standard compatibility. Most metallic pipe systems in the U.S. reference ASME B16.5 (NPS ½–24) and
The material selected for a flange encompasses several key factors, including performance, reliability, and longevity. The choice of flange material must suit the operating conditions, which include temperature, pressure, fluid chemistry, mechanical loading, and environmental exposure. In this article, we
Flanges are fundamental components in piping, pressure vessels, and countless mechanical systems. They join pipes, valves, pumps, and equipment into safe, reliable, and functional systems. Flanges are typically attached by welding, threading, or lapping, and are considered the second most
A pipe flange is a standardized, round or square rim-type element commonly used to connect pipes, valves, or equipment with bolts and a gasket. This type of connection allows for easy assembly and maintenance of piping systems. In this blog,
1. The Role of AWWA Standards When engineers and utilities design water systems, every pipe, fitting, and connection must meet various standards to ensure safety, compatibility, and long-term reliability. In the United States, this type of guidance comes from the
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
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
Two of the most referenced standards in the flange industry are AWWA C207 and AWWA C228. While they can look similar at first glance, they are engineered for very different environments and material performance. AWWA C207 flanges are typically used
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
