Whether you work in waterworks, industrial processing, energy, or manufacturing, our articles provide practical guidance written by real subject matter experts backed by API International.
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
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
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
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
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
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
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
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
