Weld Neck Raised Face (WNRF) flanges are very often utilized in industries that require high-strength, leak-proof connections on piping systems. Their long tapered production of a smooth stress distribution makes them a preferred choice for high-pressure, high-temperature, and cryogenic applications. They are widely used in oil and gas refineries, petrochemical plants, power generation, marine, and offshore usage, which securely connect piping, valves and pressure vessels. They can also be utilized in water treatment plants, chemical processing, and steam lines. WNRF flanges provide excellent durability, corrosion resistance, and reliability, which all contribute to the safe operation of critical piping systems.
