Snyder Industries 5000 Gallon HDPE Vertical Liquid Storage Tank with ASTM Certification

The full-density wall at 5,000 gallons

A 1.9 specific gravity wall is sized for a liquid nearly twice as dense as water, which is the class concentrated sulfuric acid, ferric chloride at strength and the heavy brines fall in; the wall is thickest at the bottom, where the pressure is, and the certification against ASTM D1998 is what says it was sized that way. The HDPE tank wall thickness guide explains the D1998 sizing logic and why a tall wall is inspected in the headspace, and the freeboard sizing guide works out the usable volume once thermal expansion is accounted for. The 5,000 gallon vertical tank buyers guide compares the shapes at this volume across makers; the tank sizing calculator sizes the tank from feed rate and delivery interval; the tank sizing guide covers the reserve.

Grades on the 102 x 154 inch tank, and the sizes beside it

The N43 is the 1.5 wall for coagulants and brines that never approach this density, the N40 is cross-linked polyethylene for oxidizers, and the C34 is the general grade, all in this same shell. The 5480000N40 stands 4,900 gallons on a 90 inch base, 48 inches taller in cross-linked resin, and the 32372 is the heavy-wall 5,100 on this base, 5 inches taller.

Where the pipe goes

• Access: 18 inch threaded, vented manway, 154 inches up; a dip tube for the fill, an outdoor vent on acid and caustic, and vent capacity to match the tanker.
• Outlet: order the bulkhead fitting in the material the chemical calls for; a flanged transition, an expansion joint, and a valve supported off the slab.
• Service limit: 120 F / 48 C.
• Listing: ASTM certification.

Full, the tank loads a 102 inch circle to 79,230 pounds at the rating: an engineered slab in full contact under the whole floor, with the empty tank strapped against wind, and the manway reached from a fixed platform. A single wall tank of regulated chemical needs a berm sized to its volume; where there is none, Snyder's double wall tanks on this same footprint carry the containment inside. With water in it, a 5,000 gallon tank is a fire reserve of the kind the fire-water reservoir design guide describes.

The work it does

Acid, ferric and caustic bulk storage at water and wastewater plants with a berm, dense process chemicals at plant scale, and any regulated liquid where the certification has to be on file. One chemical per tank, labeled for both inspectors at once, manway closed against vapor loss.

Freight, in plain terms

At 102 inches across and 154 inches long on the deck the 1002100N45 is oversize freight (NMFC 156600) on a flatbed at a lane rate; the freight cost estimator prices the lane to your ZIP; the figure listed here is before freight. A forklift with long forks or a small crane sets 950 pounds on the slab. Prove it with water to the manway and a hold, and check the outlet fitting, before the first load of chemical. Save the pallet; a tank that ever has to move again is easier to move on it.
