Products Description
Inhibited Admiralty Brass tubes – C44300 – have high corrosion resistance, and primarily used for tubing of steam condensers cooled with fresh, salt, or brackish water. They are also used for heat exchangers in oil refineries, in which the corrosion from sulfur compounds and contaminated water may be very severe. For industrial processes, it is used for feed-water heaters and heat-exchanger equipment.
