Product Overview: High-Performance Connection Expert for Large-Bore Lines
Our NPS 10”'' Forged Weld Neck Flange is a high-performance connecting component specifically designed for mid-to-large bore piping systems. Manufactured in strict adherence to the ASME B16.5 international standard, this flange is available across a broad pressure spectrum, ranging from Class 150lb up to Class 1500lb, meeting the demands of high-pressure, high-temperature, and severe critical service conditions.
This 10”'' large-diameter flange is produced via the forging process, ensuring superior mechanical strength and material density. The Weld Neck design facilitates the highest-strength butt-weld connection to the pipe, minimizing stress concentration and establishing it as the most reliable and leak-proof solution for critical piping systems in oil & gas, petrochemical, and power generation industries.
