Reliant Pipes & Tubes supplies 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.

We firstly possess a perfectly developed transport by which we can deliver goods directly from the warehouse to the customer. Secondly, we direct traffic, which ensures a delivery from the factory to customers from 15 tons. Cupro Nickel Tubes 70/30 that are not in stock at our own warehouse are based on the star traffic from other sites - every day! We aim at providing professional customer service with one-stop purchasing, along with superior quality control, competitive price, fast lead time and convenient transportation.
While marking we choose a specific item number as well different color shade to differentiate steel grades. We mark Cupro Nickel Tubes 70/30 as needed with the most suitable & visible marking technique.
We deliver from stock and warehousing as well as directly from the mill.
Packaging is an integral part of the product. It guarantees that the Cupro Nickel Tubes 70/30 is delivered to the customer in the required quality. For smaller orders the size of the Cupro Nickel Tubes 70/30 bundle depends on the no. of Tubes ordered, for larger orders the tubes are packed into individual bundles and in such a way that the maximum weight of 4000kg per bundle is not excedded. Bundle tied down with steel tape. Bundle tied down by steel strap underlaid by tapaten.
We can also provide Cupro Nickel Tubes 70/30 wooden box packing, cardboard boxes, plastic wrapping, using hardened paper with PE meshing (used as protection against mechanical damages of tubes), into tapaten and polyethylene sheet etc.

The two main alloys are 90/10 and 70/30. The 70/30 is stronger and has greater resistance to sea water flow; but the 90/10 will provide good service for most applications and being less expensive tends to be more widely used.
Cupro-Nickel (70%/30%) : This alloy provides corrosion resistance in high velocity (from 1 to 4 m/sec) waters, including sea water. The alloy is relatively insensitive to stress corrosion. It has good cold and hot working properties and is readily weldable.
Cupro-Nickel (90%/10%): This alloy also has very high erosion and corrosion resistance. It has very high weldability, easy for installation and high anti-fouling properties against sea microorganisms. Relatively high iron content provides better impingement attack resistance. The alloy is unique to stress corrosion cracking.
