Nickel alloy bends are important components for changing media flow direction in piping systems. Compared to standard elbows, bends have larger bending radii, significantly reducing fluid resistance and erosion wear. The nickel alloy bends supplied by Hefei Tailan Metal Co., Ltd. are manufactured from high-quality nickel-based alloy seamless pipes through multiple precision processes including cold bending/hot bending, solution heat treatment, sizing, and pickling/polishing. Featuring large bending radius, uniform wall thickness, smooth internal and external surfaces, and minimal residual stress, they are specifically designed for demanding piping systems requiring exceptional media fluidity and erosion resistance.
Difference from Elbows:
Elbow: Small bending radius (typically R=1.0D or 1.5D), mass-produced, standard component
Bend: Large bending radius (typically R≥3D), customizable for special applications
