CuNi 90/10 LR Butt Weld Elbow, ASTM B466 C70600 Corrosion Resistant Fitting

Product Specification

ASTM B466 CuNi 90/10 Butt Weld Elbow Corrosion Resistant Fitting for Marine Piping

1. Product Overview

The Copper Nickel 90/10 Elbow (C70600) is a high-performance pipe fitting designed for critical fluid conveyance systems. Manufactured from corrosion-resistant cupronickel alloy, this elbow features a 90-degree angled configuration to effectively redirect fluid flow in piping networks. Available in both seamless and forged construction, it ensures reliable performance under high-pressure and high-temperature conditions. Ideal for marine, offshore, and industrial hydraulic applications, our CuNi elbows strictly comply with ASTM B466 standards, guaranteeing dimensional accuracy and material integrity.

2. Key Technical Parameters

3. Applications

This copper nickel elbow is widely used in:

• Marine Piping Systems – shipbuilding, ballast water lines, cooling systems

• Seawater Desalination Plants – reverse osmosis feed lines, brine discharge

• Offshore Oil & Gas Platforms – hydraulic control lines, firewater systems

• Industrial Hydraulic Equipment – high-pressure fluid transmission

• Heat Exchanger & Condenser Tube Networks

4. Key Advantages

• Superior Corrosion Resistance – Excellent performance against seawater, brackish water, and chloride-induced pitting, far outperforming carbon steel and pure copper.

• Anti-Biofouling Properties – The natural copper content inhibits marine organism adhesion, reducing maintenance frequency.

• High Strength & Durability – Seamless forged construction ensures mechanical strength under extreme pressures and vibrations.

• Long Service Life – Up to 20-30 years in marine environments with minimal degradation.

• Full Traceability – Each batch comes with mill test certificates (MTC) per EN 10204 3.1.

5. Product Functions

• Flow Direction Change – Redirects fluid flow at precise 45°/90°/180° angles to accommodate piping layout requirements.

• Pressure Maintenance – Maintains system pressure integrity without leakage at connection points.

• System Flexibility – Allows pipeline routing around obstacles and space constraints in compact equipment layouts.

• Corrosion Barrier – Protects downstream equipment by minimizing internal corrosion and scaling.

6. Usage Instructions

1. Inspection – Before installation, check for surface defects, dimensional accuracy, and thread integrity.

2. Preparation – Clean pipe ends and fitting sockets thoroughly to remove debris, oil, or moisture.

3. Installation (Threaded Type) – Apply appropriate thread sealant or PTFE tape on male threads. Tighten to recommended torque values (do not over-tighten to avoid cracking).

4. Installation (Welding Type) – Follow qualified welding procedure specifications (WPS). Preheating is generally not required for CuNi alloys but ensure interpass temperature below 150°C.

5. Post-Installation – Conduct hydrostatic pressure testing at 1.5x working pressure to verify joint integrity.

6. Regular Maintenance – Periodically inspect for erosion, galvanic corrosion, or mechanical damage.
