ASTM B111 C44300 Admiralty Brass Seamless Tube For Heat Exchanger and Condenser
ASTM B111 C44300 Seamless Tube refers to a type of seamless tubing made from C44300 alloy, also known as Admiralty Brass or ARS 443. This alloy is a copper-nickel-zinc alloy with added corrosion inhibitors like arsenic (As) or antimony (Sb). The tubes are manufactured in accordance with the ASTM B111 standard, which specifies the requirements for seamless copper and copper-alloy tubes for condensers and heat exchangers.
Advantages of ASTM B111 C44300 Seamless Tubes:
Key Features:
| Feature | Description |
| Corrosion Resistance | Excellent resistance to seawater, chemicals, and biofouling. |
| Thermal Conductivity | High efficiency in heat transfer applications. |
| Mechanical Strength | High tensile and yield strength for durability in demanding environments. |
| Formability | Easily formed, bent, and welded for versatile applications. |
| Low Maintenance | Resists corrosion and biofouling, reducing maintenance costs. |
| Versatility | Suitable for marine, power generation, oil and gas, and chemical industries. |
