Products Description
Corrosion-Resistant Admiralty Brass Tubing (C44300) is a copper-zinc alloy with a small addition of tin and corrosion inhibitors, offering excellent resistance to corrosion in contaminated or saltwater water. With a copper content exceeding 70%, it combines exceptional durability, thermal conductivity, and corrosion resistance in heat transfer systems.
Corrosion-Resistant Admiralty Brass Tubing is commonly used in steam condensers, particularly those cooled with fresh, salt, or brackish water, and is trusted by industries such as power generation, oil refining, and offshore. This alloy withstands corrosive media, including sulfur compounds, and operates reliably under high pressure and high temperature conditions.
Applications
C44300 Admiralty brass tubes are commonly used in:
Steam condensers exposed to fresh, brackish, or seawater
Feedwater heaters in power generation plants
Heat exchangers in oil refineries and chemical plants
Cooling systems in marine and offshore environments
Desalination units and water treatment facilities
Thermal equipment operating under corrosive and polluted conditions
Key benefits
High corrosion resistance in contaminated water: inhibited alloy resists dezincification, pitting, and erosion in polluted and saline environments.
Reliable performance in aggressive media: withstands sulfur compounds and organic contaminants found in oil refining and chemical processing.
Thermal conductivity for efficient heat exchange: maintains stable performance across temperature cycles and varying water quality.
Good mechanical strength and ductility: suitable for high-pressure systems and thermal cycling.
Long service life in industrial environments: reduces maintenance needs in harsh conditions.
Compliance with global standards: manufactured to meet ASTM B111 and other relevant specifications.
