Heat Exchanger Tubes manufactured to ASTM B111 UNS C70600 specification are produced from high-quality Cu-Ni 90/10 copper alloy, offering excellent corrosion resistance, thermal conductivity, and durability in demanding heat transfer applications. With a 1 inch (25.4 mm) outer diameter, 14 BWG wall thickness (2.11 mm), and 10,000 mm length, these tubes are ideal for marine, power generation, desalination, and industrial cooling systems. The copper-nickel composition provides superior resistance to seawater corrosion and biofouling, ensuring long service life and reliable performance. As a leading Seamless Steel Tube Supplier in China, we deliver precision-manufactured tubes that meet strict international standards and project requirements.
