What are the key properties and benefits of Cupro Nickel 70/30 boiler tubes?
Cupro Nickel 70/30 Boiler Tubes possess several key properties and offer a range of benefits that make them a popular choice in various industries. Cupro Nickel 70/30 is a copper-nickel alloy comprising 70% copper and 30% nickel. This alloy combination results in excellent corrosion resistance, especially in marine environments and seawater or brackish water applications. The inherent biofouling and pitting corrosion resistance make Cupro Nickel 70/30 boiler tubes highly durable and long-lasting.
Furthermore, Cupro Nickel 70/30 exhibits high thermal conductivity, allowing for efficient heat transfer in boiler systems. This property helps improve energy efficiency and contributes to the overall performance of the boiler. The alloy also demonstrates good resistance to stress corrosion cracking and erosion, common challenges in boiler tube applications.

Another unique property of Cupro Nickel 70/30 is its ability to withstand high temperatures and pressures. That makes it suitable for use in demanding boiler environments with elevated temperatures and steam pressures. The alloy's excellent weldability and fabrication properties further enhance its versatility, facilitating easy installation and maintenance.
How does Cupro Nickel 70/30 compare to other materials commonly used for boiler tubes?
When comparing Cupro Nickel 70/30 to other materials commonly used for boiler tubes, it demonstrates several advantageous characteristics. Cupro Nickel 70/30 offers superior corrosion resistance compared to carbon and stainless steel materials. This property is particularly beneficial in boiler applications where seawater or brackish water exposure is common. The alloy's resistance to pitting, crevice corrosion, and biofouling contributes to its extended lifespan and reduced maintenance requirements.
Additionally, Cupro Nickel 70/30 exhibits excellent thermal conductivity, surpassing materials like carbon steel. This enhanced heat transfer capability allows for efficient energy utilization in boiler systems, improving overall performance and potentially lowering operational costs.
Regarding mechanical properties, Cupro Nickel 70/30 possesses good strength and flexibility, enabling it to withstand high temperatures and pressures often encountered in boiler applications. It balances strength and formability, allowing for ease of fabrication and installation.

Welding Process
The grade and application requirements have an impact on tube welding and forming. For the manufacturing of tiny diameter tubes, we employ TIG welding. Steel sheets are coiled and welded inside of a welding machine. The steel sheets are shaped into a coil before entering the machine. The seam between these coils is then welded to create a Tube.
Drawing/ Floating Process
Pulling a metal bar, rod, or wire through the entirety of a die to change its finish, shape, size, and/or mechanical qualities is known as floating or drawing. The tube's outer, inner, and wall thicknesses are all reduced via the tube drawing procedure. Stainless Steel Tubes benefit from maintaining the integrity of their surface.
Continuous Seamless Tube Mills
The production of seamless tubes has been transformed by continuous tube mills. These mills do away with the necessity for forging welding or filler metal, in contrast to conventional procedures. With the use of this technology, seamless pipes and tubes may be produced continuously, increasing productivity while lowering costs and improving efficiency.
Continuous Casting
A notable advancement in the production of seamless Tubes is continuous casting. The metal is solidified into a continuous billet through the continuous pouring of molten metal into a water-cooled mould. Better uniformity and enhanced mechanical qualities are guaranteed by this continuous casting technique for the Tubes.
Annealing
Metal is heated above the point of re-crystallization and cooled to room temperature during the annealing process. The molecular bonds in metal tighten when it is shaped, making it rigid. The metal is put through an annealing process to regain its ductility.
Sinking Process
Tube sinking is a drawing technique that reduces the diameter of Tubes. In this drawing technique, a tube is run through a die without the need of a mandrel. Good inner surface quality is not ensured when using a mandrel. The die angel determines the integrity of the outer surface. The die being used produces a uniform surface. A tube can be significantly smaller than it was originally. When cost is a factor, Tube sinking is ideal.
Inspection and Testing
Before sending our items to our consumers, we conduct inspection procedures to verify their integrity.
