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.

FITTING LOCATIONS GUIDE

Specifying Fitting Locations

It is very important to be as precise as possible when specifying tank fittings and accessories. Location, type and size
of fittings must be noted clearly on your drawing. If more than one fitting is being specified, mark each fitting with a
letter A, B, C etc. Dimensional drawings are available for all tanks. Download a blank generic drawing and send or
fax in with your order.

Vertical Bulk Storage Tanks

Plan View Calibration strip is at 0 degrees, in line with manway. Specify in degrees
from 0 the location of fittings.

Elevation View Indicate in inches the height
from the center of the fitting to the floor.

Example: Fitting A is at 90°, 48 up from button; Fitting B is at 180°, 30 up from bottom;
Fitting C is at 270°, 20 up from bottom.
Note: Use a dotted circle to indicate fittings which are on the opposite side of the elevation
drawing (see fitting B)

Most vertical storage tanks have 8 x8 flat sections at least every 90 degrees along the circumference at the bottom
of the side. These flats are ideal locations for bulk head fittings.

Horizontal Tanks

End View Round Horizontal

End View Leg Horizontal

Side View

Drain fittings are generally located in one of the ends of the tank, close
to the bottom. Indicate in inches any fitting(s) that are required in the
top of the tank.

Cylindrical Open Top Tanks

Plan View if more than one fitting is being specified, indicate in degrees the
location of the fittings.

Elevation View indicate in inches the height from center of the fitting to the floor.

Example: Fitting A is at 180°, 15 up from bottom; Fitting B is at 270°,
30 up from bottom.
Note 1: Use a dotted circle to indicate fittings which are on opposite
side of the elevation drawing (see fitting A )
Note 2: Never include tank flange in your measurements.

Rectangular Tanks

Indicate width, length and height of tank using inches.
Plan View indicate in inches the distance from edge of tank.

Elevation View indicate in inches the height from the center of the fitting to the
floor.

Example: 24 x 36 x 36 HT. Fitting is 18 in from side along the 36 wall,
18 up from floor.
Note: Never include tank flange in your measurements

Cylindrical Cone Bottom Tanks

Plan View if more than one fitting is being specified, indicate in degrees the location
of the fittings.

Elevation View Indicate in inches the height from the bottom of the straight side
to the center of the fitting. Do not include the cone. Stands have a lip 16 high.
Consult our sales dept. for minimum height of side fittings.

Example: Fitting A is a 0°, 15 up the straight side; fitting B is at 90°, 20 up from straight side; C is in cone flat.

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 driver’s 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 it’s 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 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 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.


STORAGE TANK SPECIFICATIONS

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.
