ASTM A350 LF2 low-temperature carbon steel (LTCS) weld neck flanges are designed for use in low-temperature applications where maintaining strength and durability is critical. Made from ASTM A350 LF2 carbon steel, these flanges are engineered to perform reliably at temperatures as low as -50°F (-45°C). The weld neck design features a long, tapered hub that allows for a smooth transition from the pipe to the flange, providing a strong and leak-proof connection. This design also helps to distribute stress more evenly, reducing the risk of failure. Commonly used in industries such as oil and gas, chemical processing, and power generation, these flanges ensure a robust, reliable joint for piping systems under demanding conditions.
