High Pressure CuNi 70/30 Copper Nickel Elbow, 90° LR Butt Weld ASME B16.9 for Marine Piping
1.Product Description
The Copper Nickel Elbow is a high-performance seamless pipe fitting made from cupronickel alloys (Cu-Ni), primarily grades C70600 (90/10) and C71500 (70/30). Manufactured by hot pushing or cold forming followed by solution annealing, it features a homogeneous grain structure, excellent dimensional accuracy, and smooth internal surfaces. All products comply with ASME B16.9, ASTM B466/B467, DIN 86090, and EEMUA 146, ensuring global interchangeability and reliability.
2.Product Applications
These elbows are specifically designed for corrosive and high‑flow environments. Major applications include:
Marine piping (ballast, cooling, fire‑fighting, bilge)
Offshore platforms and subsea pipelines
Seawater intake and brine lines in desalination plants
Condenser and heat exchanger connections in power stations
Chemical and acid‑resistant process lines
Shipbuilding and port infrastructure
3 · Product Advantages
Outstanding seawater resistance – Corrosion rate < 0.025 mm/year; no SCC or pitting.
Biofouling prevention – Copper ions inhibit barnacle and algae attachment.
High‑velocity tolerance – Safe for flow velocities up to 4‑5 m/s (seawater).
Easy fabrication – Excellent weldability (TIG/MIG) without preheat; bendable and machinable.
Long service life – Expected lifetime > 30 years in marine environments.
Low maintenance – Reduces downtime and replacement costs.
