About this product
Weld Neck Flanges are designed to be joined to piping systems by butt welding. The long tapered hub provides important reinforcement and smooth stress distribution from flange to pipe. Preferred for high-stress, high-pressure, and extreme temperature applications. The bore matches the pipe ID, reducing turbulence and erosion. Available in RF (Raised Face), FF (Flat Face), and RTJ (Ring Type Joint) configurations.
