Product Details

Admiralty Brass Alloy 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 sulfur compounds and contaminated water may be very severe, and for feed-water heaters and heat-exchanger equipment as well as other industrial processes.

Typical use	Admiralty Brass contains small amount of Tin and Arsenic, this alloys are renowned for their characteristic of superior corrosion resistance in a moderately polluted river water and clean seawater, stagnant or slow moving water. Often used for heat exchangers which are involved with operations in petroleum refineries and petrochemical plants Melting Point: 935°C • Hot Working Properties: OK Density (20°C): 8,53 g/cm3 • Cold Working Properties: Very Good
Weight Formula	Average Wall: (OD-WT) x WT x 0,0270 = Kg/m (all sizes in mm) Minimum Wall: (OD-WT) x WT x 0,0281 = Kg/m (all sizes in mm)
