ASME SB111 C44300 U-Bend Copper Alloy Tube For Heat Exchanger

• Material Composition:

  • Copper (Cu): ~70%
  • Zinc (Zn): ~28-29% (acts as the alloying agent for strength and durability)
  • Tin (Sn): ~0.8-1.2% (added to improve corrosion resistance, especially against saltwater)
  • Contains small quantities of arsenic (As) (~0.02-0.06%), which helps prevent dezincification.
  • Lead (Pb) content is minimal, ensuring compliance with safety and performance standards.

• Corrosion Resistance:

  • Exceptional resistance to dezincification, a type of corrosion caused by the selective leaching of zinc.
  • High resistance against pitting and crevice corrosion in fresh water, seawater, and brackish environments.
  • Tin content enhances its ability to withstand aggressive water conditions, particularly in marine applications.

• Thermal Conductivity:

  • Admiralty brass is recognized for its excellent thermal conductivity, making it highly effective for heat exchange and high-efficiency thermal transfer.

• Mechanical Strength and Formability:

  • Good mechanical strength with excellent ductility and formability, allowing for efficient bending and U-bend configurations without cracking or compromising the tube's structural integrity.

1. Longevity:

   • Superior corrosion and erosion resistance ensure a prolonged service life in harsh environments.

2. Heat Transfer Efficiency:

   • Its excellent thermal conductivity minimizes energy losses and enhances system performance.

3. Compatibility with Various Applications:

   • Perfect for water-cooled systems, whether for fresh water, seawater, or steam.

4. Cost-Effective Solution:

   • Competitive material cost combined with long service life results in lower total ownership costs.

The ASME SB111 C44300 U-bend tubes are particularly utilized in:

• Heat Exchangers:
  Used in systems where high thermal efficiency is critical.

• Marine Applications:
