| Although Tank
Depot's tanks are
extremely durable, improper handling and installation can result in damage to
tank, fittings, and accessories. Failure to comply with handling and
installation instructions voids all warranties. |
 |
At delivery, inspect your tank
immediately for defects or shipping damage. Any discrepancies, or product
problems, should be noted on both the driver's bill of lading and your packing
list.
|
|
When unloading your tank from
the delivery truck, avoid its contact with sharp objects. Forklift blades can
cause significant damage if proper precautions are not taken. Do not allow
tanks to be rolled over on the fittings. Large bulk storage tanks, whenever
possible, should be removed from truck bed by use of a crane or other suitable
lifting device. OSHA regulation 29CFR 1910.178 through 1910.189 addresses
specific standards for hoisting and lifting. Keep unloading area free of rocks,
sharp objects, and other materials that could damage the tank. If tank is
unloaded on it's side, carefully brace to prevent rolling. |
|
Support bottom of tank firmly
and completely. Concrete pads provide the best foundation. However, when
seismic and wind factors are not being considered, tanks with a base load
bearing of less than 800 pounds per square foot require a firm, even, compacted
bed of sand, pea gravel, or fine soil that won't wash away.Tanks with a base
load bearing of 800 pounds per square foot, or greater, require a reinforced
concrete base. Steel support stands concentrate the loaded tank weight onto the
stand leg pads. It is recommended that stands are mounted on a concrete base.
Bolting of stands is necessary to prevent movement due to agitation, wind,
seismic loads and accidental contact. |
|
Install tanks in an area that
is accessible. Ease of maintenance and removal should be considered. |
|
Test by filling tank with water
prior to use, to prevent material loss through unsecured fittings, shipping
damage, or manufacturing defects. Tanks should be tested for a minimum 5 hours. |
|
Plastic screw on bulkhead
fittings are designed to be hand tightened. Overtightening can cause fittings
to leak.
|
|
Support sides of rectangular
tanks. In general, tanks with heights greater than 18" must be supported.
However, specific applications must be considered: smaller tanks with contents
that have high specific gravity and/or elevated temperatures must be supported. |
|
Do not mount heavy equipment on
tank sides. |
|
Do not allow weight on tank
fittings. Fully support pipes and valves. |
|
Use expansion joints to prevent
damage at fittings from the differential expansion
and contraction of the piping and tanks. |
|
Tanks are designed for use only
in the atmospheric storage of chemicals, never for
vacuum or pressure applications. |
|
Immersion heaters should never
touch the walls of the tank. Minimum spacing should be
3" - 4" from wall.
|
|
Refer to the chemical capability
chart on this site as a guide. Be certain tank, fittings, and fitting gasket
material are compatible with chemicals at the anticipated operating
temperatures. Contact our technical staff for information on chemicals not
listed, or when uncertain conditions exist. |
|
Protect tanks from impact,
especially at temperatures below 40 degrees F. |
|
Confined spaces must be
considered hazardous. Do not enter tank without first taking proper
precautions. |
|
Tank sizes as listed are
nominal and calibrations on molded tanks are only approximates, but provide an
indication of volume. Polyethylene tanks expand and contract which will effect
volume. The degree in which this occurs depends on the size of the tanks, wall
thickness, specific gravity of contents, temperature of contents and
ambient temperatures. |
