Cupro Nickel Tubes

Tube Tech produces a vast range of cupro nickel tubes to satisfy all customer requirements in terms of outer diameter, wall thickness and tempers to suit the intended applications.

The cupro nickel tubes are available in a variety of combinations, the main combinations manufactured by Tube Tech are:
Cupro Nickel Tubes 90/10
Cupro Nickel Tubes 70/30

This alloy has very high erosion and corrosion resistance. It has very high weld ability, easy for installation and high antifouling properties against sea microorganisms. Relatively high iron content provides better impingement attack resistance. The alloy is unique to stress corrosion cracking. This form of copper alloy gives the best service life under the most adverse conditions.

90/10 Cupro Nickel Tubes

This form of cupro nickel tubes produced by Tube Tech possess excellent resistance to corrosion by sea water as well as high resistance to erosion corrosion and air-impingement attack. The addition of iron results in 90/10 performing as good as 70/30 in salt water service heat exchangers. These 90/10 Cupro Nickel tubes have good strength and ductility at ordinary temperatures and relatively high strength and other mechanical properties at elevated temperatures.
These 90/10 cupro nickel tubes are widely used in condensers, coolers and heat exchangers where resistance to corrosion and erosion is paramount, yet maintaining a high thermal conductivity rate. To be used preferably in marine conditions.
These 90/10 cupro nickel tubes are produced in a range of outside diameter, wall thickness various temper conditions to achieve the required mechanical properties and grain size. The mechanical and dimensional characteristics of our products satisfy the most demanding orders that require tight tolerances.

70/30 Cupro Nickel Tubes

Tube Tech produces smooth bore 70/30 cupro nickel tubes of the highest standard, rigorously tested to make sure they are suitable for the exacting requirement of condensers and heat exchangers. These cupro 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 cupro nickel tube gives the best service life under the most adverse conditions because of improved corrosion resistance and almost insensitive to stress corrosion. These cupro 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 cupro 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.
