What is Low Temperature Carbon Steel LF787 Flanges?

Low Temperature Carbon Steel LF787 Flanges are constructed from carbon steel with carefully controlled levels of carbon, manganese, phosphorus, sulfur, and silicon, along with alloying elements like nickel to enhance low-temperature toughness. These flanges offer excellent impact resistance at temperatures as low as -50°F (-45°C) while maintaining strong tensile and yield strength. Their fine-grain microstructure ensures high ductility and reliable weldability. Designed to prevent brittle fractures in cold conditions, LF787 Flanges provide tight, leak-proof connections and uphold structural integrity even in extreme operating environments.

Uses of Low Temperature Carbon Steel LF787 Flanges

LF787 Flanges are extensively used in industries such as oil and gas, LNG, petrochemical plants, refineries, and power generation facilities, where piping systems must function reliably in low-temperature or cryogenic conditions. Typical applications include connecting pipelines, pressure vessels, heat exchangers, storage tanks, and other essential equipment that transport or process low-temperature fluids or gases. Their impressive impact strength, ductility, and weldability minimize the risk of leaks and brittle failures. LF787 Flanges ensure safe and efficient flow control and structural performance, making them essential for demanding cold-service operations.
