Copper Nickel 90/10 Flanges

Copper nickel 90/10 flanges specifications What are copper nickel 90/10 flanges?

These flanges essentially contain copper (90%) and nickel (10%) with small additions of iron and manganese. Copper nickel 90/10 flanges are the most popular and cost-effective choice for most applications. They offer strength, corrosion resistance, and protection from bio-fouling.

Copper Nickel 90/10 Blind Flange supplier in India

How does the composition of a cuni 90-10 socket weld flange impact its performance in corrosive environments?

Blind flanges lack a bored center and usually isolate or seal off a piping section. A 90/10 copper nickel blind flange can withstand harsh environments in petrochemicals or chemical processing industries. This property emanates from its chemical composition: the addition of iron and manganese.

We deliver only the best to our customers, which is why we consistently invest in the latest technology to manufacture 90/10 copper nickel flanges, check how Copper Nickel 90/10 Forged Flange used for marine and offshore applications

What makes 90/10 copper nickel flanges popular for marine and offshore applications?

The petrochemicals sector frequently uses 90/10 copper nickel forged ring for their tolerance for corrosion, temperature range, and high pressures. The fatigue strength and high-pressure handling of a din 2.0872 weld neck flange help it service offshore mining and desalination.

Manifest alloys work tirelessly to supply Cu-Ni 90/10 Slip On Flange and UNS C70600 Socket Weld Flanges that are not only strong and reliable, but also undergo a rigorous testing process to guarantee their quality

How do testing methods determine the quality and reliability of a cu-ni 90/10 slip on flange and a uns c70600 socket weld flange?

Complete testing of a c70600 flange detects flaws and structural defects by a direct-reading spectrograph (spectrometry), hydrostatic tests, ultrasonic, or magnetic detection. It ensures the durability of a copper nickel 90/10 slip on flanges in stressful environments. It typically connects to piping by fillet welds outside and inside. In contrast, a CUNI 9010 blind flange uses a socket to insert the pipe. Then, the connection gets secured with an outer fillet weld. Intensive testing guarantees the performance of a copper nickel 90/10 forged flange in offshore refineries and marine industries.

With a focus on quality and versatility, our Cu-Ni 90/10 Plate Flanges and DIN 2.0872 threaded flange are an excellent choice for a variety of industries, including but not limited to power generation, shipbuilding, and paper and pulp

How does the durability and corrosion resistance of a copper nickel 90/10 weld neck flange and a din 2.0872 threaded flange affect their quality and versatility?

These flanges connect to the piping with a screw thread. A din 2.0872 threaded flange has good corrosion and fatigue resistance. It is also an electrical conductor and resists bio-fouling. A versatile copper nickel 90/10 weld neck flange has a raised face or hub and works in distiller tubing and saltwater piping.
