Key Specifications / Features
This WN weld neck flange is forged from ASTM A182 F55 super duplex stainless steel and manufactured to ASME B16.5. It is Class 300 rated, sized 10-inch DN250, and engineered to match SCH20 pipe. The tapered hub optimizes stress distribution at welded joints. Boasting exceptional tensile strength and strong anti-corrosion capacity, this flange fits high-pressure piping. It is widely chosen for offshore oil and gas platforms, seawater pipelines, and chemical plants facing aggressive corrosive service environments.
