ANSI B16.47 Series A Class 300 Flanges

Typically, ANSI B16.47 Series A Flanges are crafted from carbon steel, stainless steel, or alloy steel, and they come in pressure classes of 150, 300, 400, 600, and 900. What sets Series A flanges apart are their thicker cross-sections, larger bolt circles, and fewer bolts compared to Series B, which enhances their performance under severe pressure conditions. They boast impressive mechanical properties, including high tensile strength, excellent load-bearing capacity, and outstanding fatigue resistance. These flanges are generally available in weld neck and blind configurations, designed to be compatible with gaskets featuring ring-type joint (RTJ) or raised face (RF) sealing surfaces.
