ANSI B16.48 flanges are extensively applied in industrial processes where high performance and safe connections are essential. Typically used in the oil and gas, chemical, petrochemical, and power generation sectors, these flanges are best suited for joining large-diameter pipes. They are utilized in systems transporting fluids like steam, water, gas, and other high-pressure materials. Their heavy-duty construction enables efficient sealing in high-pressure and high-temperature conditions. ANSI B16.48 flanges are also utilized in offshore and onshore usage, providing leak-proof joints and durability in aggressive working conditions.
