70 / 30 CUPRO NICKEL TUBES

We are considered as a major 70/30 Cupro Nickel Tube Manufacturer, Exporter and Supplier from India. The Cupro Nickel Tubes offered by us are manufactured using premium quality raw materials ensuing high durability, tensile strength and resistivity to adverse conditions. The Copper Nickel Tubes are available in varied sizes and dimensions as per the specifications and drawings provided.

We 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. 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.

Sea Water: 

a) Dissolved salts from 10000 ppm.
b) Absence of abrasive suspended solids.
c) Polluted with H2S and Ammonia.
Permissible average velocity of water 3 – 4 meters/sec

We are counted amidst the prime Copper Nickel Alloy Tubes Manufacturers in India. The 90 / 10 Cupro Nickel Tubesoffered by us are manufactured using premium quality raw materials ensuing high durability, tensile strength and resistivity to adverse conditions. The Copper Nickel Tubes are available in varied sizes and dimensions as per the specifications and drawings provided.

These 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. Forms a protective film which is multi-layered in flowing seawater. Resists marine bifouling. 

Sea Water: 

a) Dissolved salts more than from 1500 to 3000 ppm.
b) Suspended solids more than 25 ppm.
c) H2S or Ammonia is less than 1 ppm.
Permissible average velocity of water 2.5 – 2.7 meters/sec.
