When it comes to copper nickel welded pipes, these are crafted by shaping copper-nickel alloy plates or strips—typically in 90/10 or 70/30 compositions—into cylindrical forms and expertly welding the edges together. These pipes are renowned for their outstanding resistance to seawater corrosion, biofouling, stress corrosion cracking, and erosion. They boast high mechanical strength, excellent thermal conductivity, and good ductility, making them ideal for operations at both high and low temperatures. The welded design guarantees precise dimensions, smooth internal surfaces, and consistent wall thickness, all of which enhance fluid transport efficiency and extend service life.
