Snyder Industries 3650 Gallon HDPE Vertical Liquid Storage Tank with ASTM Certification

Most of a tanker in the middle wall

A water-rated wall is for water and nothing heavier; the heaviest wall is for concentrated acid; a 1.5 wall is the middle, sized for brine, fertilizer solution and coagulant as delivered and every water application, with margin. Rotationally molded polyethylene tanks are sized to ASTM D1998, and the way a tank meets the density it is rated for is in the wall; the HDPE tank wall thickness guide explains the sizing logic and why the headspace is where a wall ages, and the freeboard sizing guide works out the usable volume once thermal expansion is accounted for. Full, it puts 45,662 pounds on a 102 inch circle at the rating: an engineered slab bearing under the entire floor, sized by the concrete pad sizing guide, with the empty tank strapped against wind. The tank sizing calculator tells you whether 3,650 gallons covers the draw, and the tank sizing guide covers days of supply.

Grades on the 102 x 126 inch tank, and the sizes beside it

The N45 is the 1.9 wall in this same shell, 193 pounds heavier, for ferric at strength and the heavy brines; the C26 and C37 are the general grades and the C26-BLACK the black one for sun. The 32288 is the water tank at 3,500 gallons on a 96 inch base at this height, and the 5190000N40 stands 3,900 gallons of cross-linked resin on a 90 inch base at 163 inches for a smaller pad.

Still deciding between these? Freight to your ZIP often settles it; the wider tanks ship differently. Or call 866-418-1777 and we will walk the table with you.

Access and outlet

• Access: 18 inch threaded, vented manway, 126 inches up; filled by hose, tote pump or truck through a dip tube, vented outside on anything that fumes, and size the vent for the delivery pump.
• Outlet: tell us the liquid when ordering and the bulkhead fitting is matched to it; a flexible connector between the bulkhead and hard pipe, an expansion joint, and the valve supported off the slab.
• Service limit: 120 F.

The white wall shows the level in daylight; fit a sender read at ground level so nobody climbs for a number, and fit a low-level float switch so a pump never runs dry. Mount the pump below the outlet so it primes by gravity, keep the manway closed against vapor loss, and keep the tank out of direct sun where the liquid is light-sensitive. Where it freezes, insulate or drain the outlet valve and the first length of pipe; the body takes ice from the top down without harm.

The delivery hookup

A delivery truck's pump can push air out faster than a stock vent can pass it, so the vent is sized for the unload rate or the fill goes through a dedicated top bulkhead with its own vent line. A fill pipe to the floor keeps the liquid from free-falling and foaming. Watch the first delivery from the first gallon to the last, checking the slab edge and the outlet fitting as the level rises, and the log takes the date and strength of every load that follows.

Put to use

Coagulant, brine and fertilizer solution at plants and farms, well storage for a community system, a rain cistern under a large roof, stock water at a big operation, and one cell of a fire reserve. One liquid per tank, labeled.

Truck, crane and the first hour

At 102 inches across and 126 inches long on the deck the 8190000N43 ships as oversize freight at a lane rate rather than a class rate; the freight cost estimator prices the move to your ZIP, and the price on this page is before freight. A forklift with long forks sets 780 pounds on the slab. Fill it to the manway once, hold it, and check the outlet fitting before the pump goes on. Write the outlet fitting size and material on the site plan; the replacement is ordered by those two words.
