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.
