LTCS (Low-Temperature Carbon Steel) ASTM A350 LF2 socket weld flanges are designed for use in low-temperature environments while offering robust strength and durability. Manufactured from ASTM A350 LF2 carbon steel, these flanges are ideal for applications where maintaining structural integrity at temperatures as low as -50°F (-45°C) is crucial. Socket weld flanges are characterized by their design, which allows the pipe to fit into a socket-like recess, then be welded around the circumference of the pipe and flange. This design provides a strong, smooth, and leak-proof connection suitable for high-pressure and low-temperature applications. Common applications include the oil and gas industry, chemical processing, and power generation.
