CuNi30Mn1Fe Seamless Copper Nickel tube in tube heat exchanger Cu Ni 70 30 C71500 3/4'' X 0.065'' X 20''
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.
