ANSI B16.5 Class 300 flanges are used extensively in high-pressure application industries like oil and gas, petrochemical, and power plants. The flanges are suitable for pressures up to 740 psi at ambient conditions. They are used extensively to join pipes, valves, and other equipment for safe, leak-free joints. The Class 300 rating renders them ideal for medium to high-pressure systems, with a compromise between strength and cost-effectiveness. The flanges are also available in a range of materials such as carbon steel, stainless steel, and alloy steel, allowing versatility across environments and temperatures.
