Snyder Industries 2000 Gallon ASTM XLPE Black Heavy Duty Vertical Storage Tank

Low roof, heavy liquid, 90 inches of floor

Height is what most sites have least of, and 88 inches is what this tank asks for before the lid, the fill line and the vent are added. That makes it the shape to reach for in a chemical room with ductwork overhead, in a pump house, or under a mezzanine, and the 90 inch circle it stands on is the trade: 16,680 pounds of water on a molded floor that bears across the whole base, or up to 31,692 pounds of contents at the rating on this sheet. Engineer the slab for that, level and in full contact under the entire floor, and leave a walking gap around it so the base can actually be looked at. Strapping goes to the four tiedown lugs and to anchors set in the concrete, done while the tank is empty, because a light shell with a heavy rating spends part of its life nearly empty and that is when the wind gets a hold of it. Check the tie-downs after the first hot week and again in the fall. The rest of the site work is the ordinary discipline for a dense liquid: a berm sized to the tank where it is required, a hard surface under the connection instead of gravel, and no traffic lane where a forklift can reach the shell. A black wall keeps light off the liquid and takes the ultraviolet a white one absorbs, and it also hides the level, so the gauge is a sender read at the ground. Size the volume against the draw with the tank sizing calculator, and take the reserve and the freeboard a warming liquid needs from the tank sizing guide.

The 2,000 gallon shells and the 1,900 beside them

Within the 90 by 88 inch shell the choice is wall, and this is the heavy one: the 1.9 rating on this sheet is the reason to pay for it, and a liquid near the weight of water does not need it. The lighter grade of the same shell is rated lower on its own sheet, weighs less empty and rides at a higher freight class; the three 5050000 tanks are the same footprint at 340 pounds, each rated as its own sheet says. The real alternative is shape, not wall. The 1780200N40 puts 1,900 gallons on a 72 inch circle and stands 119 inches to do it, which is the tank for a narrow floor and a tall room, the exact opposite of this one, and the 5090000C26 buys 500 more gallons by standing 107 inches on the same 90 inch base. Choose this tank when the liquid is dense and the ceiling is low.

Height or floor the limit? The table has both shapes; freight to your ZIP is quoted on each row, or call 866-418-1777 with the site.

Eight lifting lugs, one manway, no factory outlet

• Outlet: the sheet lists "1 Manway / Lid" as the outlet and gives no bottom fitting size, so the draw-off is specified at order. On a 1.9 duty, the liquid named on the order is what the bulkhead, gasket and bolting are selected for.
• Access: 18 inch threaded, vented manway at 88 inches, low enough to reach from a short platform rather than a tower, which is one of the quiet advantages of this shape.
• Handling: eight lifting lugs for setting it and four tiedown lugs for holding it, both listed on the sheet.
• Service limit: 140 F / 60 C. Warranty: 3 year.

A short tank gives you less suction head than a tall one, and that is the thing to design around here rather than to discover at start-up. With only 88 inches of liquid column above the base, a pump mounted above the outlet will struggle for a prime as the tank empties; put it below the fitting, keep the suction line short and straight, and add a low-level float so it stops before it draws air. Since the lid is within easy reach, this is also the tank people open out of habit, so latch it and keep a sender on it instead. Put the name of the one liquid on the shell, look at the wall above the working level with a light every time the lid comes off, and support the first valve off the pad so the pipe run never hangs on the fitting. Where it freezes, wrap or trace the valve and the first run.

Plating lines, dosing rooms, and dense feedstock

The plants that buy the heavy grade at 2,000 gallons are the ones with a dense liquid and no room: a metal finisher with acid or caustic beside the line, a municipal plant dosing a heavy coagulant out of a cramped chemical room, an oilfield or mining yard with brine, and a manufacturer holding a dense feedstock next to the machine that uses it. Whether the duty actually calls for a crosslinked wall or a high density one is a chemistry question, worked through in the crosslinked versus high density polyethylene guide. If you are comparing this against the other makers at the same volume, the 2,000 gallon vertical tank comparison lines up the shells, the ratings and the fittings side by side. A fire reserve is a different job with its own sizing rules and belongs in a water-duty tank, which the fire-water reservoir design guide covers.

475 pounds on the deck at class 300

Freight is class 300 as the sheet lists it, out of Marked Tree, Arkansas, and a 475 pound tank in a 90 by 88 inch cube loads as a single piece that a carrier can get under a standard trailer roof. Price your ZIP in the freight cost estimator; the listed price is before freight. Set it with straps to the lifting lugs or under the base and never a hook in the manway, land it on the anchors, and tighten the tie-downs the same day. Water test before the product: fill to the manway, hold it a shift, and read the base and the fitting you specified. A last word on the delivery itself, because it is where these tanks get hurt: take the strapping off before the forklift touches it, and never drag the shell across the deck to get at the lugs. The vent screen is the cheapest part on the tank and the one that saves it; look at it every time the manway opens.
