Ring Type Joint RTJ Welding Neck Flange
The Welding Neck Flange (WN Flange) is a critical component in piping systems requiring strength, reliability, and durability. Designed with a butt weld end connection, this flange ensures smooth transition between flange and pipe, minimizing stress concentration and enhancing overall system integrity. The bevel end, manufactured to ANSI B16.25 standards, facilitates precise and secure welding for leak-proof joints and long-lasting performance under various operating conditions.
Our product line includes specialized materials to meet specific industry requirements, including duplex 2205 EN 1092-1 weld neck flanges for exceptional corrosion resistance and 13CrMo4-5 flanges for high-temperature strength applications. All flanges are engineered to meet EN 1092-1 standards, ensuring compatibility and interchangeability with piping components worldwide.
