Avaliable in 30 and 45 degree slopes, sizes range from 15-11,500 gallons
For fast and complete drainage of liquids and powders, Sierra's cone
bottom bulk poly tanks are offered in a wide variety of sizes and diameters. All designs are supported by
heavy-duty steel stands, with up to 2" schedule 40 tubing construction. |
Available with seismic zone 4 and UBC 110 mph wind restraint tie-down systems
Most Sierra cone-bottoms 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 has the ability to cater a poly tank's material construction to an application's
specific requirements. We offer the following resin options:
- High-density linear polyethylene (HDLPE)* in black & natural white color
- Cross-linked, high-density polyethylene (XLPE) in black & natural white
color
- Opaque white -- "black-out" resin
|
Specific gravity rating's are based on the industry's most severe calculation
Sierra utilizes a
600 psi hoop stress measured from the top of the cone poly tanks dome to calculate our posted specific gravity
for every vertical poly tank we manufacture. As a result, Sierra'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. |
