What are the Benefits of Flanges?
Flanges are taking an important part in many piping systems, they provide a secure way to join pipes, valves, pumps, and other equipment. Flanges are widely used in industries like oil and gas, waterworks, chemical processing, and power generation because they offer dependable performance and are backed by established standards which include AWWA, ANSI/ASME, DIN […]
Flange Connections for Different Pipe Types
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 ASME B16.47 (NPS 26–60); waterworks systems commonly reference AWWA C207 (steel) and AWWA C228 (stainless). […]
Top Materials Used in Flange Manufacturing
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 present an overview of common flange materials, discuss their properties, advantages, limitations, and typical applications. […]
How Flanges Work: Function and Purpose
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 common joining method after welding. Without proper flange selection and installation, industries risk costly leaks, […]
Main Parts & Specifications of a Flange
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, we outline the main components of a flange, including key specifications such as size, pressure rating, […]
AWWA Standards and Their Application to Flanges
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 American Water Works Association (AWWA). For more than a century, AWWA standards have provided the technical foundation […]
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 […]
Choosing Between AWWA C207 and C228 Flanges
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 in clean water systems and general infrastructure due to their strength and cost-effectiveness, while AWWA […]
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 […]
