Description:

?

Copper?nickel tubes are commonly used in condensers, coolers and heat exchangers where resistance to corrosion and erosion are necessary. The mechanical and dimensional characteristics of our products satisfy the most demanding orders that require tight tolerances.

?

Spezilla supply 70/30 copper nickel tubes for industries all throughout?the world. At Spezilla, you will find competitive prices and high-quality 70/30 copper?nickel tubes.

?

We produce?smooth bore 70/30 copper?nickel tubes of the highest standard, rigorously tested to make sure they are suitable for the exacting requirement of condensers and heat exchangers. These copper?nickel tubes have the highest resistance to stress-corrosion cracking. These tubes are available in a variety of outside diameter, wall thickness and tempers to meet the requirement. Superior dimensional control with specified mechanical properties offers trouble free performance and cost saving.

This form of copper?nickel tube gives the best service life under the most adverse conditions because of improved corrosion resistance and almost insensitive to stress corrosion. These copper?nickel tubes are used in heat exchangers where severe erosion and corrosion have been experienced, especially at elevated temperatures, high velocities and extreme turbulence of the circulating media. These copper?nickel tubes have an important bearing not only on the performance of heat exchangers but also on the cost and delivery cycle time of the condenser and heat exchangers where they are used.
