Overview
Product overview
Series A Flanges are a standard type of flange recognized by the American National Standards Institute (ANSI). They are characterized by their smaller diameter and thinner thickness compared to Series B or Series C flanges, which are designed for higher-pressure applications. Series A Flanges are typically made from materials such as carbon steel, stainless steel, or cast iron and are available in a range of sizes to suit different piping systems.
