Q: What is the composition of Admiralty Brass C44300?

Admiralty Brass C44300 consists of 70–73% copper, 26–28.7% zinc, 0.8–1.2% tin, and 0.02–0.06% arsenic. Tin and arsenic improve resistance to dezincification and corrosion in seawater and industrial cooling systems.

Q: What standard governs Admiralty Brass heat exchanger tubes?

Admiralty Brass heat exchanger tubes and condenser tubes are manufactured as per ASTM B111 and ASME SB111 standards. Equivalent international standards include DIN 1785, EN 12451, and JIS H3300.

Q: What is the difference between seamless and welded Admiralty Brass tubes?

Seamless Admiralty Brass tubes are cold drawn or rolled and offer higher strength and pressure resistance, making them suitable for critical heat exchanger applications. Welded tubes are more cost-effective and are commonly used in low-pressure condensers and HVAC systems.

Q: What sizes are available for Admiralty Brass condenser tubes?

Admiralty Brass condenser tubes are available in outer diameters from 6 mm to 219.1 mm, with wall thickness ranging from 0.7 mm to 12.7 mm and lengths up to 20 metres. Custom sizes can be manufactured based on project requirements.

Q: Do you supply Admiralty Brass U bend tubes?

Yes, Admiralty Brass U bend tubes and condenser U-shaped tubes are supplied as per ASTM B111 / ASME SB111 standards for use in shell and tube heat exchangers and surface condensers.

Q: What testing is performed on Admiralty Brass condenser tubes?

Admiralty Brass condenser tubes undergo hydrostatic testing, eddy current testing, chemical analysis, tensile and hardness testing, PMI testing, intergranular corrosion testing, and pitting resistance testing. Third-party inspection is also available.

What are Admiralty Brass Condenser Tubes?

Admiralty Brass Condenser Tubes are premium copper-zinc alloy tubes enhanced with small percentages of arsenic and tin, conforming to ASTM B111 / ASME SB111 standards. These tubes are manufactured under UNS C44300 (Werkstoff Nr. 2.0470) designation and are widely used in heat exchangers, condensers, surface condensers, and feed water heaters across power plants, refineries, and marine industries.

The tin content (0.8–1.2%) in Admiralty Brass C44300 acts as a dezincification inhibitor, while arsenic (0.02–0.06%) further stabilises the alloy against corrosion in polluted, slow-moving, or stagnant water. This makes Admiralty Brass Heat Exchanger Tubing the preferred choice for applications involving seawater cooling, industrial cooling water systems, and steam condensers.
