Characteristic of C44300:
C44300 is a Copper Zinc Alloy containing tin and small amount of Arsenic, which is added as an inhibitor against dezincification. The pressure of Tin imparts to the alloy good corrosion resistance in a moderately polluted river water and clean seawater, either stagnant or slow moving (upto about 2 mtrs/sec.). The most common and wrought form is tube for heat exchange equipment. Guide to the selection of tube material:Clear river, Lake or Canal Water.a. Dissolved salts more than 2000 ppm.b. Chloride less then 20 ppm.c. H2S and Ammonia is less than 1 ppm.d. Suspended solids less than 25 ppm.e. For temperature more than 2000C and less than 4500 C.Permissible average velocity of water 1.8-2.0 meters/sec.
