Polyethylene flat bottom, dome top vertical tanks have capacities from 22 gallons to the worlds' largest 16,500 gallons. Safe double wall tank systems are available to 10,000 gallons. Poly cone or conical bottom tanks are available in 15 to 11,500 gallons. |

They are available in verticals, horizontals, cone bottom, uprights, and safe polyethylene double wall tanks, systems, and poly containment basins.
One of the above tank was used for storing sodium hypochlorite at 17% and were warranteed for three [3] years by the manufacturer. This configuration is shipped daily throughout the United States because of value and availability. Taken off the truck this containment system is ready to go. Or try our poly safe double wall tanks or our poly safe tank systems; a vertical or upright poly tank with a poly containment basin. Read about our poly containment basins and double wall, self-contained covered, plastic chemical storage tanks.
This has, and continues to be Sierra Sales's, and Sierra Sales's customers' experiences. Sierra Sales offers a better warranty along with better pricing for this service. Order Phamplet 96 at this site and see for yourself. Why has cross-linked poly been spec'd so often? At one time it was the "only" resin available. The original cross-linked polyethylene resins are no longer available and, the rotational equipment is usually out-dated compared to our modern equipment.
Sierra Sales offers a full range of product designs including: closed or open top poly vertical (upright) tanks in flat or cone bottoms, horizontal, horizontal leg, plastic IBCs, DOT and UN approved. Small batch or tanks, the worlds' largest selection of poly containment basins and safe poly double wall tanks. Our plastic IBCs are priced to travel.

Capacities and Dimensions
Exceed ASTM D-1998-97 design standards The American Society for Testing and Materials (ASTM) committee formulated design standard for all vertical polyethylene storage poly tanks to assure consistency and safety in poly tank designs and manufacturing. All Sierra Sales vertical poly tanks are designed to exceed ASTM standard requirements. As a result, Sierra Sales poly tank walls are thicker in critical hoop stress areas. |
Available with IBC 2006 seismic and 150 mph wind restraint tie-down systems Most Sierra Sales verticals incorporate molded-in tie-down lugs, which are designed to interface with a cable tie-down system. Many poly tank designs have the ability to be modified for even more stringent specification standards when required. |
Material options for a diverse range of application requirements Sierra Sales has the ability to cater a poly tank's material construction to an application's specific requirements. We offer the following resin options:
|
Specific gravity rating's are based on the industry's most severe calculation Sierra Sales utilizes a 600 psi hoop stress measured from the top of the poly tanks dome to calculate our posted specific gravity for every vertical poly tank we manufacture. As a result, Sierra Sales's specific gravity ratings deliver a stronger poly tank with a higher safety factor. Standard specific gravity choices are 1.5 and 1.9, other ratings are available upon request. Specific gravity reflects material weight. For example, 1.5 S.G.=12 lb/gallon, and 1.9 S.G.=15.2 lb/gallon. |
* Complies with U.S. Food and Drug Administration Regulation 177.1520. | &All poly materials are UV stabilized for long-terrm outdoor service. |
![]() 1.9 specific gravity, 6,500 gallon vertical poly tanks are utilized to store a variety of acids and caustic materials at a chemical distribution plant. |

![]() When deciding on choosing a particular industrial polyethylene (PE or poly) processing TANK there are specific and general issues that must be identified to define the actual tank, the configuration of the tank and fittings, and let us not forget the cost. Cost will include the tank, the fittings and factory installation, and DELIVERY. Bulk poly storage tanks are large, and transporting these vessels can be very expensive. Deciding on the proper safe poly processing tank is dependent on the information given to the manufacturer. As always, the more accurately the issues are identified and addressed at the beginning of the process, will assure the proper HDLPE (or XLPE) safe tank will be installed, and at a lesser cost, in time and dollars, and longer life of the poly tank to the end-user. We will help you chose the perfect tank for your needs. |
![]()
All of our tanks have been
designed to the newest standards, and the only standard that applies to
polyethylene tanks, ASTM D1998-06. However there are certain limitations
and caveats which we can discuss with the customer to assure the proper
vessel is designed and supplied.. Consult your SIERRA SALES representatives on material construction recommendations for your company's particular application
We offer both high density linear polyethylene (HDLPE) and high density
cross linked polyethylene (HDXLPE) tank resins to properly and correctly
provide the storage and processing vessels that offer best in class
performance, and at the most economical cost. We have five (5) different
regionally located manufacturing plants, so we always attempt to assure
freight and transport costs are held to a minimum. |
Rotationally Molded Polyethylene Tanks Offer These Advantages
Difference in resin. The advantages our HDLPE resin has over other rotomolded
linear resins in tank applications Over XLPE
1. Over Linear, Medium and Low Density Polyethylene:
superior impact and stress-crack resistance
- Improved weatherability
- Broader chemical resistance
- Lower notch sensitivity
2. Crosslink versus Linear:
"The most important advantage that crosslinkable polyethylene (XLPE) tanks have over linear polyethylene (LLDPE)
tanks is that XLPE has a much higher molecular weight than LLDPE. In general, as the molecular weight of polyethylene
increases, the environmental stress cracking resistance (ESCR), part impact strength, elongation, weathering, toughness,
and tensile at elevated temperatures are improved."
This in fact is a true statement; however Snyder is using a TRUE HDLPE and not a LLDPE. In fact, during the molding
cycle the density of resins changes and testing has shown us that we end up with a higher density with our HDLPE
than with the CL200 XLPE.
We feel very confident that our studies and case histories can help us to determine the best resin for the application.
Sii has always taken pride in our ability to get the full development of the physical properties of the resins
which translate into chemical resistance and tank life.
Crosslinked vs. linear Advantages:
The most important advantage that crosslinkable polyethylene (XLPE) tanks have over linear polyethylene (LLDPE)
tanks is that XLPE has a much higher molecular weight than LLDPE. IN GENERAL, as the molecular weight of polyethylene
increases, the environmental stress cracking resistance (ESCR), part impact strength, elongation, weathering, toughness,
and tensile at elevated temperatures are improved.
Wall thickness is not the only factor relevant to determining the strength of the tank. Proper material cure is
more important than wall thickness in determining tank strength. Material cure is highly dependent upon the time
of exposure to heat conducting through the tooling and the plastic material. Excessive exposure to high temperature
will degrade the plastic material and cause a weak part. The ideal cure cycle is to reach the proper curing temperature
as fast as possible, maintain that temperature for the correct period of time, and to cool the part and tooling
at the proper rate of part temperature decrease. The superior Sii manufacturing process and oven capacity makes
it possible to reach the proper cure temperature quickly and avoid the material degradation caused by slow oven
temperature rise. Therefore, it is improper manufacturing technique to compensate for poor material cure with excessively
thick tank walls.
