3D Pipe Bends | Butt-Weld Pipe Bends | Carbon Steel, Stainless Steel, Alloy Steel, Duplex & Nickel Alloy
Elite manufactures and supplies 3D Pipe Bends for industrial piping systems requiring smooth directional changes and reliable flow performance. A 3D Pipe Bend has a centerline radius equal to three times the nominal pipe diameter (3D), providing a gradual change in direction compared with tighter-radius bends.
Elite offers 3D Pipe Bends in carbon steel, stainless steel, alloy steel, duplex, super duplex, copper-nickel, nickel alloys and other project-specified materials. Available configurations include 45°, 90° and other specified bend angles, with custom diameters, wall thicknesses and end connections to meet project requirements.
Our 3D Pipe Bends are suitable for oil and gas pipelines, refineries, petrochemical plants, power generation facilities, water transmission systems and industrial process piping. Products can be supplied according to applicable standards, approved drawings, material specifications and project-specific inspection requirements.
