Products Description
Our Advantages
1. Material Control
- C70600 is composed of 90% copper and 10% nickel, offering resistance to seawater corrosion and biofouling, while possessing excellent thermal conductivity, making it suitable for use in heat exchangers.
- Our B466 C70600 Tube undergoes chemical composition testing and certification to ensure compliance with ASTM B466 / ASME SB466 standards, and the alloy composition is confirmed by factory certificates.
2. High Dimensional Accuracy
- Our tubing is manufactured using a cold-drawing process, ensuring tight dimensional tolerances. Each tube undergoes rigorous measurement and inspection before shipment to ensure its suitability for heat exchangers or piping systems.
- Strict control is maintained throughout the manufacturing process, with rigorous testing of drawing, straightening, and sizing operations to minimize ovality, wall thickness variations, and outer diameter variations.
3. Good Machinability
- The tubing has excellent welding properties and can be welded using most conventional welding methods, such as TIG and MIG welding.
- The C70600 copper-nickel alloy offers excellent weldability and ease of formability. The tubing passes flaring tests, maintaining seal integrity while withstanding installation stresses. The tubing can be cold-bent, flared, or expanded without surface cracking or wrinkling.
4. Corrosion Resistance
- C70600 has strong corrosion resistance, resisting attack from seawater, brine, and other corrosive environments, making it ideal for marine, offshore, and chemical applications.
- Our B466 C70600 Tube exhibits excellent resistance to seawater corrosion and biofouling, providing a service life exceeding 20-30 years in marine condensers and seawater systems, reducing maintenance costs.
5. Packaging and Transportation
- We offer various packaging options, including plastic caps, plastic film, woven bags, and wooden crates, to prevent damage or contamination of the pipes during transportation. We support moisture-proof and rust-proof packaging, and each package has a traceability code.
- We offer various transportation methods, including sea, air, and land transport.
application areas
- Marine Industry: Seawater cooling systems, fire-fighting water systems, and ballast water systems.
- Seawater desalination plants: Used in brine heaters and evaporator tubes due to their resistance to chloride corrosion.
- Power plants: Used in condensers and heat exchangers for treating seawater or brackish cooling water.
- Chemical processing: Suitable for heat exchangers and piping systems exposed to weakly acidic solutions.
- Offshore oil and gas platforms: Suitable for seawater cooling, fire-fighting water, and hydraulic systems.
- HVAC and refrigeration: Suitable for air-cooled and water-cooled heat exchangers requiring corrosion resistance.
