UNS C44300 Admiralty Brass Tube PDF
What is ASTM B111 C44300 copper tubing?
Admiralty Brass tubes - ASTM B111 C44300 - has good corrosion resistance and is specially used for tubing of steam condensers cooled with fresh, salt or brackish water. Admiralty metal tubes are also used for heat exchangers in oil refineries, in which corrosion from sulphur compounds and contaminated water may be very severe, and for feed-water heaters and heat-exchanger equipment as well as other industrial processes.
