Exceed ASTM D-1998-96 design standards

The American Society for Testing and Materials (ASTM) committee formulated design standard for all vertical polyethylene storage tanks to assure consistency and safety in tank designs and manufacturing.  All Snyder vertical tanks are designed to exceed ASTM standard requirements.  As a result, Snyder tank walls are thicker in critical hoop stress areas

Available with seismic zone 4 and UBC 110 mph wind restraint tie-down systems

Most Snyder verticals incorporate molded-in tie-down lugs, which are designed to interface with a cable tie-down system.  Many tank designs have the ability to be modified for even more stringent specification standards when required.

Resin Option

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

 Snyder utilizes a 600 psi hoop stress measured from the top of the tanks dome to calculate our posted specific gravity for every vertical tank manufactured.  As a result, specific gravity ratings deliver a stronger 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 materials are UV stabilized for long-term outdoor service

1.9 specific gravity, 6,500 gallon vertical tanks are utilized to store a variety of acids and caustic materials at a chemical distribution plant
