ASTM A182 Gr. F22 Alloy Steel Long Weld Neck Flanges are designed for use in high-pressure and high-temperature environments. These flanges feature a long neck that provides additional reinforcement and allows for a smoother transition of stress from the flange to the pipe, reducing the risk of fatigue and failure. Made from Grade F22 alloy steel, they offer excellent resistance to heat and corrosion, making them suitable for applications in the chemical processing, oil and gas, and power generation industries. The flanges conform to ASTM A182 standards, ensuring high quality and reliability. Long weld neck flanges are commonly used in applications where pipes are subject to significant mechanical stress and need robust and durable connections.
