Copper Nickel 70/30 Pipe

Copper nickel 70/30 pipe specifications

What is a Copper Nickel 70/30 Pipe?

These performance-focused pipes use a 70% copper and 30% nickel constitution and perform consistently in marine, abrasive, and polluted environments. A copper nickel 70/30 pipe contains iron (0.7%) and manganese (1%) too, exhibiting good weldability and pitting resistance.

We supply UNS C71500 welded pipe and Cu-Ni 70/30 Pipes in India, for high-pressure systems

Can Copper Nickel 70/30 pipes be used in high-pressure systems?

High-pressure petroleum and oil and gas sectors often use cupro nickel 70/30 pipes. They boast a tensile strength of 359 MPa and adapt well to extreme temperatures and high-velocity flows. Buyers can procure this piping from SCH 10 to XXS for pressure classes 150 to 2500.

Manifest Alloys is a premier provider of UNS C71500 Pipe and Copper Nickel 70-30 Seawater Pipes, offering a comprehensive selection of sizes and specifications

What are the specifications of a Copper Nickel 90/10 Pipe?

These pipes are less suited to high-velocity waters than an ASTM B466 cupro nickel 70/30 seamless pipe but still enjoy immense popularity due to their cost-effectiveness. The standard sizing is from ½ to 6 inches.

Customers can order these products per international standards, for instance, a UNS C71500 pipe, DIN, or ASTM specifications. They are available in many finishes, like mill, polished, bright, etc., across wall thicknesses from 0.2 to 120 mm. We are committed to thoroughly testing products via spectro analysis and positive material identification.
