Sunrise Industries manufactures Cu-Ni 90/10 EFW Pipes and Rectangular Tubes for specialized piping applications in marine, shipbuilding, and industrial plants. These tubes have excellent corrosion resistance in high-velocity seawater conditions due to added manganese and iron. Rectangular tubes are often used in structural applications, seawater piping, and auxiliary systems. The pipes and tubes are available in multiple lengths, wall thicknesses, and custom dimensions. Their strength and reliability make them suitable for offshore platforms, desalination plants, and chemical processing plants.
