Single Wall Tanks (UL-142)
FMC Tanks supplies a variety of
Single Wall Tanks in capacities ranging from 5 gallons to 40,000
gallons. Single Wall Tanks are available in either Rectangular
or Cylindrical Geometries and can be dimensionally modified
to accommodate unique space requirements. Single Wall Tanks are
constructed using a single sheet thickness of steel as the primary
tank. Material thickness will vary depending on the size and geometry
of the tank. All single wall tanks are air-tested at the factory
at 5.0 psig to verify tank performance and integrity. Single Wall
Tanks have no inherent “secondary means of containment” in the event
the primary steel tank leaks or is ruptured. Single Wall Tanks are
satisfactory for many industrial applications. Please consult your
local fire code officials and regulatory agencies for additional
guidance with projects requiring single wall tanks.
Single Wall Steel Tanks are manufactured
in accordance with Underwriters Laboratories Standard UL142, Steel
Aboveground Tanks for Storage of Flammable and Combustible Liquids.
This construction standard mandates minimum steel gage thickness
meeting ASTM specifications that must be used in the construction
of single wall steel tanks that carry the Underwriters Laboratories
UL142 label. All UL142 tanks supplied by FMC Tanks are supplied
with the properly sized normal and emergency vent openings to affect
the safe venting of tanks in the event of a fire or rapid temperature
increase. Customized tank openings and equipment can be ordered
and installed at the factory to satisfy specific system requirements.
FMC Tanks can supply your tank in carbon steel, stainless steel
or aluminum. Interior linings and/or exterior coatings can be applied
to effect compatibility with unique liquid products or to provide
long-term corrosion, chemical and impact/abrasion resistance.
