ASTM A105 carbon steel long weld neck flanges are specifically designed for high-pressure and high-temperature applications where additional strength and durability are required. These flanges feature an extended neck, which provides a longer weld area for a more robust connection to the pipe, reducing stress concentrations and enhancing the overall integrity of the joint. Made from ASTM A105 carbon steel, these flanges are ideal for critical applications in industries such as oil and gas, petrochemical, and power generation. The long weld neck design ensures a smoother transition from the pipe to the flange, facilitating better performance under extreme conditions.
