Трубы из сплава меди: Понятие о CuNi 90/10 и CuNi 70/30

CuNi трубы, composed of copper and nickel, are known for their excellent resistance to seawater corrosion and marine biofouling. Our company manufactures CuNi 90/10 seamless pipes up to a maximum diameter of 457mm and CuNi 70/30 pipes up to 219mm. These pipes are widely used in naval ships and marine engineering.

Введение

Are you looking for durable and corrosion-resistant piping solutions for marine applications? CuNi pipes might be what you need. These pipes, available in CuNi 90/10 and CuNi 70/30 varieties, are specially designed to withstand the harsh marine environment. In this article, we will explore the differences between CuNi 90/10 and CuNi 70/30 pipes and highlight the capabilities of our company’s manufacturing processes.

Understanding CuNi 90/10 Pipes

CuNi 90/10 pipes consist of 90% copper and 10% nickel, offering excellent resistance to seawater corrosion and marine biofouling. These pipes are essential for various marine applications, including naval ships and marine engineering.

Manufacturing Challenges:

Producing ultra-large diameter and ultra-thick wall CuNi 90/10 pipes is challenging. It requires advanced equipment and skilled personnel. Our company, equipped with a 5500-ton extrusion press, excels in manufacturing large diameter and thick-walled CuNi 90/10 pipes. This capability allows us to produce high-quality pipes efficiently.

Achievements:

Successfully produced a φ419*9mm (diameter 419mm, wall thickness 9mm) CuNi 90/10 tube for marine applications.

Our company can produce CuNi 90/10 seamless pipes with outer diameters ranging from 8mm to 457mm.

For welded CuNi 90/10 pipes, we can achieve an outer diameter of up to 810mm.

Understanding CuNi 70/30 Pipes

CuNi 70/30 pipes, also known as C1500 or CuNi30Fe1.6Mn pipes, are harder than CuNi 90/10 pipes and offer superior resistance to seawater corrosion. These pipes are ideal for more demanding marine environments.

Manufacturing Capabilities:

The high hardness of CuNi 70/30 pipes makes them challenging to draw into shape. Typically, these pipes have an outer diameter under 108mm. However, our company has advanced to produce CuNi 70/30 tubes with outer diameters of 133mm, 159mm, and up to a maximum of 219mm with wall thicknesses ranging from 4-6mm.

Заключение

CuNi pipes, particularly CuNi 90/10 and CuNi 70/30, are crucial for marine applications due to their excellent corrosion resistance and durability. Our company stands out in the industry by successfully manufacturing large diameter and thick-walled CuNi pipes, meeting the highest standards.
