U Pipe Bends
U Pipe Bends | Butt-Weld Pipe Bends | Carbon Steel, Stainless Steel, Alloy Steel, Duplex & Nickel Alloy
Elite manufactures and supplies U Pipe Bends for industrial piping systems, heat exchangers and specialized process applications. Designed in a U-shaped configuration, these bends allow the pipeline to change direction and return along a parallel path. Depending on the application, U bends can be manufactured from seamless or welded pipe, with specified bend radii, diameters, wall thicknesses and leg lengths.
Elite offers U Pipe Bends in carbon steel, stainless steel, alloy steel, duplex, super duplex, copper-nickel, nickel alloys and other project-specified materials. Stainless steel U bends provide corrosion resistance for suitable operating environments, while duplex and nickel alloy options can be selected for applications requiring specific mechanical properties and resistance to corrosive media.
Our U Pipe Bends are suitable for heat exchangers, condensers, industrial process equipment, refineries, petrochemical plants, power generation facilities and selected piping systems. Products can be supplied according to customer drawings, applicable standards, operating conditions and project-specific inspection requirements.
