Low Temperature Carbon Steel ASTM A350 LF2 ring type joint (RTJ) flanges are specifically designed for applications requiring high-pressure and low-temperature resistance. Manufactured from ASTM A350 LF2 carbon steel, these flanges are suitable for temperatures as low as -50°F (-45°C) and provide exceptional strength and toughness. The RTJ flange design features a metal ring inserted into a groove in the flange face, which creates a tight, leak-proof seal when bolted together. This design is ideal for critical applications in industries such as oil and gas, chemical processing, and power generation, where reliable, high-pressure, and low-temperature performance is essential.
