Copper Nickel 70/30 Pipe fittings

Copper nickel 70/30 pipe fittings specifications

What are copper nickel 70/30 pipe fittings/ buttweld fittings?

Corrosion-resistant, sturdy, and durable, these piping components comprise 70% copper and 30% nickel, besides iron and manganese (0.4-1.5%). Copper nickel 70/30 pipe fittings show durability and longevity in extreme temperatures (up to 1038°C) and corrosive environments.

Manifest Alloys can assist you with high-quality, global copper nickel 70/30 buttweld fittings like elbows, reducers, and tees.

We are an authorised Cu-Ni 70/30 stub end supplier in India; also see copper nickel 70/30 elbow applications

What are the applications of Copper Nickel 70/30 Pipe fittings?

A copper nickel 70/30 elbow works in the oil and gas, paper, and pharmaceutical industries. Textiles, architecture, power plants, and wastewater management sectors utilise these fittings as well. Buyers can procure a DIN 2.0882 concentric reducer for heat exchangers, condensers, and dairy/food processing.

To verify the pressure-bearing capacity and durability of our DIN 2.0882 concentric reducer and cu-ni 70/30 long radius elbow, we use pressure testing methods such as hydrostatic testing and pneumatic testing

How does our company ensure the durability of Copper Nickel 70/30 Pipe fittings/Buttweld Fittings?

Quality management is our cornerstone. Each 70/30 cupro nickel reducing tee undergoes destructive and non-destructive testing to diagnose defects and non-compliance. We use approaches like ultrasonic examination, radiography, and tensile strength testing.

Customers can trace a UNS C71500 long radius elbow through the heat numbers on the MTC (Mill Test Certificate).

We believe that quality is key, which is why our CUNI 70 30 elbow and 70/30 cunifer reducing tee are made from the best materials and undergo rigorous testing

What makes Copper Nickel 70/30 Pipe fittings special and unique?

A 70/30 copper nickel tee handles high-velocity seawater without corrosion or deformation.

  • Works in contaminated seawater
  • Resists impingement
  • High thermal stability
  • Good electrical conductivity

This material also resists biofouling, i.e., barnacle growth, while adapting to elevated temperatures.
