UNS C71500 Cupro Nickel 70/30 Seamless Pipe Corrosion Resistant Marine Tube

• High Strength & Durability: Exhibits high tensile strength and good elongation, allowing the fittings to withstand vibration, bending, and thermal stress without cracking .

• Thermal Stability: Maintains performance at operating temperatures up to 300°C .

• Versatility: Available in a wide range of types, including Elbows, Tees, Reducers, Crosses, Caps, and Unions .

6. Usage Instructions

1. Inspection: Before installation, inspect all fittings for damage, dimensions, and wall thickness.

2. Preparation: Cut the pipe ends squarely. For butt-weld fittings, bevel the pipe ends for proper weld penetration. For socket-weld fittings, leave a slight gap between the pipe and the socket shoulder to allow for thermal expansion during welding.

3. Alignment: Ensure the fitting and pipe are correctly aligned to avoid stress on the joint.

4. Welding: Perform welding by qualified personnel using appropriate procedures for copper-nickel alloys. For socket-weld, a fillet weld is applied around the joint .

5. Cleaning: After installation, clean the welded area to remove slag and discoloration.

7. Precautions

• Storage: Store in a dry, covered area to prevent damage and corrosion. The protective anti-tarnish coating should remain intact until installation.

• Handling: Avoid impact with hard surfaces to prevent deformation, especially for thin-walled fittings.

• Welding: Use proper welding techniques and filler materials specifically designed for copper-nickel alloys to ensure corrosion resistance and joint integrity.

• Temperature: Do not exceed the maximum operating temperature of 300°C for prolonged periods to avoid material degradation .
