Our industrial
copper tubes and
copper pipes can be
widely utilized in
the design of
seawater systems for
their excellent
resistance to
corrosion and
biofouling and many
other excellent
properties. Copper
corrodes at
negligible rates in
unpolluted air,
water, and deaerated
nonoxidizing acids.
Copper alloy
artifacts have been
found in nearly
pristine condition
after having been
buried in the earth
for thousands of
years, and copper
roofing in rural
atmospheres has been
found to corrode at
rates of less than
0.4 mm in 200 years.
Copper alloys resist
many saline
solutions, alkaline
solutions, and
organic chemicals.
However, copper is
susceptible to more
rapid attack in
oxidizing acids,
oxidizing
heavy-metal salts,
sulfur, ammonia
(NH3), and some
sulfur and NH3
compounds.
Copper is widely
used in applications
like freshwater and
seawater supply
lines, heat
exchangers,
condensers,
shafting, valve
stems, and marine
hardware - in which
resistance to
seawater, hydrated
salt deposits, and
biofouling from
marine organisms is
important.
