Snyder Industries 5600 Gallon ASTM XLPE Black Vertical Storage Tank

The lightest tank in this shell still loads the slab

Low profile is the whole point, and the pad is the whole cost. Standing 102 inches tall, this tank fits under a shed roof, inside a low chemical room, or out on an exposed pad where height would mean engineered anchors, and at 1,150 pounds empty it is the easiest tank in this group to set. None of that changes what the ground has to do. A rotationally molded floor bears on its own floor and on nothing else, so the eleven foot ten inch circle carries 46,704 pounds of plain water, or 70,056 pounds if the liquid uses the rating on this sheet, and it carries it evenly only if the slab is level, cured and in full contact. Engineer it to the concrete pad sizing guide rather than pouring by rule of thumb, and berm it to the tank wherever the liquid is regulated, sizing the berm before the tank is ordered rather than after an inspector asks. Band it while it is empty even though the wind has little to grip, because a light empty tank moves more easily than a heavy one and a black shell grows and shrinks in the sun every day. The black wall keeps daylight off the liquid and takes the ultraviolet that ages a pale shell; it also hides the level completely, so a gauge belongs in the install, and the level gauge selection article compares what actually lasts in chemical service. Run 5,600 gallons against the draw between deliveries in the tank sizing calculator, and take the reserve and the freeboard from the tank sizing guide.

The low 5,600s, and the 5,500 and 6,000 on a ten foot base

Among the four walls in this mold, this is the one to buy for ordinary chemistry, and the reason is money rather than modesty: a rating you never load is wall you paid to make and freight you paid to move. The 5250000N48 is the heaviest wall in the identical shell at 1,350 pounds, listed on its own page and rated as its own sheet says, and it is the right answer only when the liquid is genuinely dense; the 5250000N42 shares that heavier empty weight and the 5250000N40 shares this one. If the constraint is floor rather than ceiling, the 7000000N40 stands 5,500 gallons on a 120 inch base at 132 inches, and the 7000000C34 puts 6,000 gallons into that same narrower footprint. Pick the footprint your building has and then pick the lightest wall the liquid allows.

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.

The base connection on a tank eight and a half feet tall

• Outlet, first: the sheet lists the outlet as 10, which is the field as published and not a pipe size. No bottom fitting diameter, material, thread or gasket is given anywhere on this sheet and none is invented here. Tell us the liquid, the flow and the pump at order and we confirm what this molding accepts before anything is drilled.
• Top opening: an 18 inch threaded, vented manway 102 inches up, the most reachable manway in this family, which is a real operating advantage and also the reason to write a rule about keeping it closed.
• Fill and vent: a dip tube to the floor to keep the incoming stream from foaming the headspace, a vent piped outdoors on anything that fumes, and the vent sized to the delivery pump so a fast fill does not pressurise the shell.
• Handling and hardware as listed: ladder lugs and one flange line.
• Service limit: 140 F / 60 C. Warranty: 3 year. Rating: specific gravity 1.5 as the sheet gives it.

Eight and a half feet of liquid gives a modest suction head, which is not a problem if the pump is placed for it: below the base connection, close to it, with a short straight suction run and a low-level float that stops it before it draws air. The first valve is carried on its own support off the pad, with a flexible element between the tank and hard pipe, and nothing rigid bolts to the shell, because a wide tank moves more across its diameter with temperature than a narrow one does and the pipe run has to absorb that rather than the wall. One liquid goes in one tank with its name on the wall in letters a driver reads from the cab. Where the site freezes, put the trace heat and insulation on the base piping and the first valve; the body itself takes ice from the top down without harm.

Shed roofs, reuse trains and berms

This is the bulk vessel for a plant that has floor and no height: hypochlorite or another treatment chemical delivered by the tanker at a water or wastewater plant with a low chemical building, a feed or fertilizer solution under a shed roof at a co-op, a rinse solution in a shop where the crane rail sets the ceiling. Where a reuse train needs a dark, quality-banded holding stage between treatment steps, the industrial water reuse tank topology article shows where a vessel of this size and shape sits. If containment rules apply, the double wall freeboard sizing guide works out the usable volume a contained vessel really returns, and a fire reserve remains a separate specification in a water-rated vessel, which the fire-water reservoir design guide sets out.

Class 400 out of West Virginia

The sheet gives class 400 from Philippi, West Virginia at 1,150 pounds shipping weight, and it gives the heavy wall in the same shell a different class; both are printed as listed and neither is explained here. What that means in practice is that the class on the quote should be checked against the part number rather than assumed from the shell, and that the lane and the width do most of the work in the final number anyway: 142 inches across is an over-width load, so the truck needs room to turn and the site needs a forklift with long forks or a small crane to take it off the side. Put the ZIP into the freight cost estimator before the order goes in; the listed price is before freight. Lift with straps under the body, never a sling through the manway, set it on a cured pad in one move, and water-test it to the manway before the working liquid, watching the whole circumference of the base. Keep a spare gasket for the base connection from day one, because that is the part that chooses a holiday weekend to fail on. Write the outlet fitting size and material on the site plan; the replacement is ordered by those two words.
