When it comes to copper nickel welded tubing, the process involves shaping copper-nickel alloy strips into tubular forms and expertly welding the edges together. Typically available in 90/10 or 70/30 compositions, this tubing boasts impressive corrosion resistance in seawater and marine settings, along with high mechanical strength and thermal conductivity. The alloy is also resistant to biofouling, stress corrosion cracking, and erosion, making it ideal for operations at both high and low temperatures. Welded tubing ensures precise dimensions, consistent wall thickness, and a smooth internal surface, which promotes efficient fluid flow and heat transfer.
