d) Determine inorganic material limitations such as pressure,
temperature, and concentrations of corrosive liquid.
Plastics.
Synthetic organic materials are subject to:
10.6.1.2
a)
Temperature limits.
b)
Expansion characteristics.
c)
Acceptable jointing capability.
d)
Approval by NAVFACENGCOM, Code 04.
Metals which are resistive to their environments,

Passive Metals.
such as:
a)
Copper and its alloys, except in alkaline conditions.
b) Aluminum and its alloys, except in areas affected by sea water,
brackish water containing sea water or within 3 miles (4.83 km) of sea coast.
c) Lead and its alloys.
Lead is seldom used due to possibility of
lead poisoning.
d)
Zinc-coated materials.
e) Cast iron alloys; austentitic gray, high silicon, iron-
chromium-nickel, ni-resist, ductile.
f)
Stainless steels.
g)
Hastelloys.
Expensive and should only be used in justifiable
applications.
h)
Monel.
i)
Columbium.
j)
Zirconium.
k)
Titanium.
Metal Protection. Ferrous metals are not stable in most
10.6.1.4
environments; they must be protected by isolating them from their
environments. Refer to Table 23 for applicable protective coatings for
corrosion control. Internal coatings of tanks and exterior coating of buried
tanks are not subject to this table. Interior coatings of tanks should suit
