Snyder Industries 4650 Gallon HDPE Vertical Liquid Storage Tank with ASTM Certification

A tanker load on the small pad, 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, and 1,200 pounds of resin is what that takes on this shell. 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 a wall this tall is inspected from the top, in the headspace. Full, it puts 58,172 pounds on a 102 inch circle at the rating: a full-contact engineered slab beneath the entire floor, per the concrete pad sizing guide, the tank strapped against wind when empty, with the manway reached from a fixed platform. The tank sizing calculator tells you whether 4,650 gallons covers the draw, and the tank sizing guide covers days of supply.

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

The N45 is the 1.9 wall in this same shell, 413 pounds heavier, for ferric at strength and the heavy brines; the N40 and N42 are cross-linked polyethylene for oxidizers, the N42 the heavy wall, and the N46 another linear grade at this weight. The 7000500N40 lays 4,600 gallons of cross-linked resin down to 116 inches on a ten foot base, and the 5480000N40 stands 4,900 on a 90 inch base at 202 inches.

Connections

• Access: 18 inch threaded, vented manway, 154 inches up; filled by truck through a dip tube, vented outside on anything that fumes, and size the vent for a tanker's unload rate.
• 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 a float switch at low level shuts the pump off before it 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.

Delivery day at the manway

The driver's pump can deliver faster than the manway vent can breathe, 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. Somebody stands at the tank for the whole of the first delivery, watching the slab edge and the outlet fitting as the level rises, and the log takes the date and strength of every load that follows.

What it holds in practice

Coagulant, brine and fertilizer solution delivered by tanker at plants and farms, well storage for a community system, a rain cistern under a large roof, and a fire reserve of the kind the fire-water reservoir design guide describes, where the height gives a pump a flooded suction. One liquid per tank, labeled.

Getting it to the pad

At 102 inches across and 154 inches long on the deck the 8210000N43 ships as oversize freight on a flatbed at a lane rate; the freight cost estimator gives the flatbed number for your ZIP, and the listed price is before freight. A forklift with long forks or a small crane sets 1,200 pounds on the slab. Fill it to the manway once, hold it, and check the outlet fitting before the pump goes on. Note the pad height and the outlet height on the site plan while the tape is out; the next pipe run will need both.
