STANDARD: BS, ASTM,
DIN, NFA, JIS, IS
Product Application Area : Power Plants, Desalination
Plants, Ship Building & Ship Repair, Heat Exchangers and
Radiators, Refineries, Offshore Oil rigs, Condensers,
Evaporators, Ferrules, Distillers.
Characteristics : A Copper Zinc Alloy containing
Aluminium and small amount of Arsenic which is added as an
inhibitor against dezincification. Inhibited Aluminium Brass
resists the action of high velocity salt and brackish water and
is commonly used for condenser tube. The outstanding
characteristic of Aluminium Brass is the high resistance to
impingement attack. Tubes of this alloy are recommended for use
in marine and land power stations where cooling water velocities
are high and where inhibited admiralty brass has failed from
impingement. Guide to the selection of tube material: Sea Water:
a. Dissolved salts more than 2000 ppm.b. Suspended solids more
than 30 ppm.c. H2S or Ammonia is less that 1 ppm.Permissible
average velocity of water 2.0 - 2.5 metres/sec.
