300# ANSI Stainless Steel Flanges

ANSI Class 300# raised face stainless steel flanges are used in piping systems to connect pipes, valves, pumps, or other equipment, creating a secure, leak-tight seal for moderate-pressure applications. The "Class 300#" designation indicates they are designed to handle a maximum pressure of approximately 740 psi at ambient temperatures (e.g., 20°C/68°F) for stainless steel, per ANSI/ASME B16.5 standards, though pressure ratings decrease with increasing temperature. The raised face design, featuring a 1/16" raised surface, enhances sealing by concentrating pressure on a gasket, and stainless steel provides excellent corrosion resistance and durability.
