MATERIAL
SELECTION
|
|
We offer you a
selection of materials that are by far the best suited for
molded tanks and containers for use with
aggressive corrosive chemicals as well as food products. Our
35 plus years of experience in rotational molding,
combined with our professional staff of chemical, mechanical
and plastics engineers, enables us to provide you
with the highest quality rotationally molded tanks and containers
available in the industry.
The following
is a brief description of these materials:
|
|
Polyethylene
A high quality thermoplastic that has outstanding resistance
to both physical and chemical attack. The overall general
toughness and excellent chemical resistance to a wide array
of wet and dry industrial chemicals and food products
make polyethylene ideally suited for storage tanks and containers.
|
|
Polyethylene
is translucent and its natural color ranges from slightly off
white to creamy yellow, depending on wall
thickness and type. Ultraviolet light stabilizers are added
for use in outdoor applications. Colors are available on
request for a nominal up charge. BPA-Free Material. |
|
A) Linear Polyethylene
Linear Polyethylene is available as low, medium and high
density. Most products offered in this catalog are molded
of linear medium density polyethylene (LMDPE) and linear high
density polyethylene (LHDPE). They have superior
mechanical properties, high stiffness, excellent low temperature
impact strength and excellent environmental stress
crack resistance. The linear polyethylene used meets specifications
contained in FDA regulation 21CFR177.1520
(c) 3.1 and 3.2 and so may be used as an article or a component
of articles intended for use in contact with food,
subject to any limitations in the regulations. Maximum operating
temperature for linear polyethylene is 140° F. BPA-
Free Material.
|
|
B) Crosslinkable
Polyethylene
Crosslinkable polyethylene is a high density polyethylene
that contains a crosslinking agent which reacts with the
polyethylene during molding, forming a crosslinked molecule
similar to a thermoses plastic. This reaction improves
toughness and environmental stress crack resistance. Crosslinked
Polyethylene (XLPE) is not weldable and does
not meet FDA requirement 21CFR177.1520. Maximum operating
temperature of crosslinked polyethylene is 150° F.
|
|
2)
Polypropylene
Polypropylene is a rigid plastic that has a higher operating
temperature limit than polyethylene: 212° F. It offers good
chemical resistance, has a high resistance to stress crack,
and is autoclavable. Polypropylene (PP) is not recommended
for applications in sub-freezing temperature or where high impact
strength is needed. A rough, irregular interior surface
is common characteristic of molded polypropylene. |

Considerations
to Material Selection |
|
Elevated
Temperatures
Continued or prolonged service with contents at elevated temperatures
can shorten the life of a tank. The effects of
the temperature will depend on the chemical content and its
specific gravity, tank size and configuration, material of
construction, wall thickness and if there are any external supports
on the tank. |
|
Exposure
to Ultraviolet Light
Unprotected thermoplastics exposed to sunlight for an extended
period of time, absorb ultraviolet (UV) light, which
can cause discolorations, embrittlement and eventual cracking.
Fluorescent lighting has a similar effect. Elevated tem-
peratures can accelerate the embrittling process. These products
are molded from materials utilizing the latest
technology for UV stabilizers which greatly reduce the harmful
effects of UV light. For greater protection, keep tanks
out of direct sunlight or order dark colored tanks which will
further retard the effect of UV light. |
|
Environmental
Stress Cracking
Certain surface active materials, although they have no chemical
effect on polyethylene, can accelerate its cracking
when under stress, such as liquid detergents and ultra pure
water- (see our chemical compatibility Chart.)
Elevated temperatures tend to accelerate the cracking. Although
all polyethylenes are subject to stress cracking,
some are more resistant to it than others. The degree of stress
on the plastic has a direct bearing on its resistance,
therefore a tank and system should be designed to minimize stress.
Chemtainer.com tanks are molded visually stress
free, employing materials that are highly resistant to environmental
stress cracking, and hence are less prone to cracking
than fabricated tanks. Stress cracking agents are surface active
materials. Proper care should be taken to reduce stress
at fillings, bands, tie down lugs, etc. |

Tank
Handling Installation and Use Guidelines
|
|
Although
our 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.
1. At delivery, inspect your tank immediately for defects or
shipping damage. Any discrepancies, or product problems,
should be noted on both the drivers
bill of lading and your packing list.
2. 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 its side, carefully brace to prevent
rolling.
3. 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 wont wash away. Tanks with
a base load
bearing of 800 pounds per square foot, or
greater, require a reinforced concrete base. Steel support stands
concent-
rate 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.
4. Install tanks in an area that is accessible. Ease of maintenance
and removal should be considered.
5. 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.
6. Plastic screw on bulkhead fittings are designed to be hand
tightened. Over tightening can cause fittings to leak.
7. 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.
8. Do not mount heavy equipment on tank sides.
9. Do not allow weight on tank fittings. Fully support pipes
and valves.
10. Use expansion joints to prevent damage at fittings from
the differential expansion and contraction of the piping
and tanks.
11. Tanks are designed for use only in the atmospheric storage
of chemicals, never for vacuum or pressure
applications.
12. Immersion heaters should never touch the walls of the tank.
Minimum spacing should be 3 - 4 from wall.
13. Refer to the chemical capability chart we can get for you,
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.
14. Protect tanks from impact, especially at temperatures below
40° F.
15. Confined spaces must be considered hazardous. Do not enter
tank without first taking proper precautions.
16. 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. |

1.0 DESCRIPTION
OF TANK
1.1 SPECIFICATIONS
1.2 GENERAL
These
are one piece tanks, rotationally molded of linear medium
or high density polyethylene or high density
crosslinkable polyethylene (XLPE). Refer to material type
in the tank charts for availability. Tanks come in a
variety of shapes, are available in closed head designs with
flat bottom (IC, IA & IX series), conical bottom
(JA &
JC series), round horizontal (LC & LA series) or oval
horizontal (MC & MA series).These tanks can
be
furnished with various accessories as per customer specifications
and are capable of holding aggressive
chemicals
at atmospheric pressure. Open top mixing and processing tanks
are available in cylindrical, conical
bottom
and rectangular designs.
2.0 MATERIALS
2.1 LINEAR POLYETHYLENE
A
high quality, chemically resistant plastic with high stress
crack and impact resistance. Linear polyethylene is
translucent and exhibits properties that are ideal for applications
that are exposed to low temperatures and/or
high impact. Unlike thermosets, linear polyethylene is weldable,
thus allowing for greater flexibility when
designing
modification to our standard tanks. The plastic complies with
USDA and FDA regulations for storage
and processing of food. Linear polyethylene is fully recyclable
and thereby provides a convenient method of
disposal.
2.2 CROSS-LINKED POLYETHYLENE
High
density cross-linked polyethylene has excellent low temperature
impact and environmental stress-crack
resistance. This polyethylene is a thermoset, thus does not
permit the utilization of welded tank connections.
Cross-linked polyethylene does not have USDA or FDA compliance
for storage of processing edibles and is
not
recyclable.
2.3 ULTRA VIOLET LIGHT STABILIZERS
AND FILLERS
The
plastic does contain a minimum of 0.25 to a maximum of 0.50
long term U.V. stabilizer. It does not contain
any fillers.
2.4 PIGMENT
Pigment
can be added at purchaser's request. These pigments would
be compatible with the polyethylene and
will not exceed 0.5% dry blended and 2% compounded in of the
total weight.
