ASME B16.5 Weld Neck Flange, ASTM A182 F55, 10 Inch, 300 LB
Key Specifications / Features
Made in compliance with ASME B16.5, our 10-inch (DN250) Class 300 weld neck flange uses ASTM A182 F55 super duplex stainless steel and pairs with SCH20 piping. The tapered hub structure greatly lowers stress concentration at weld connections, improving long-term operational safety. Suited for high-pressure industrial piping, it performs reliably in offshore oil & gas, seawater conveyance, and chemical processing facilities with corrosive process fluids.
