Sunrise Industries offers Cu-Ni 70/30 Seamless Butt Weld Pipe Fittings (UNS C71500) ideal for shipbuilding, offshore platforms, and desalination plants. These fittings ensure leak-proof connections in high-pressure and high-velocity systems. Their seamless construction provides superior mechanical strength, corrosion resistance, and long-term reliability. Available in various diameters, lengths, and wall thicknesses, they are customizable to suit project-specific requirements. Common applications include piping networks for seawater, bilge and ballast systems, fire-fighting, and hydraulic lines.
Sunrise Industries manufactures Cu-Ni 70/30 Long Radius and Short Radius Elbows, as well as Reducers for seamless integration into industrial and marine piping systems. These fittings provide smooth fluid flow, minimize pressure drop, and resist corrosion from saline and brackish water. Applications include offshore oil rigs, naval ships, power plants, and desalination units. All fittings are manufactured to UNS C71500 and ASTM standards, ensuring high performance, durability, and compliance with global quality norms.
Cu-Ni 70/30 Buttweld Tees, Crosses, and Stub Ends are designed for efficient fluid distribution in piping systems. These fittings are used in offshore, marine, and industrial applications where corrosion resistance and high tensile strength are required. Manufactured from UNS C71500 alloy, they maintain structural integrity in high-pressure seawater environments. Available in various sizes, wall thicknesses, and custom specifications, these fittings ensure reliable, leak-proof performance for complex piping networks.
