Snyder Industries 16500 Gallon XLPE Heavy Duty Vertical Storage Tank

Lincoln, Nebraska ships it, and nothing about the lane is standard

Book the transport before you book the tank. The 5380000N42 is molded at Lincoln, Nebraska and moves at class 300, but the number that governs the delivery is not the class: it is 142 inches across and 257 inches long lying on a deck. That is an oversize load with permits, a route survey, and in some states an escort, and it arrives on a trailer that has to be able to reach the pad and then be unloaded by a crane with the reach to stand 5,600 pounds upright in one pick. Lincoln is a good centre of gravity for that kind of move, with straight interstate runs east, west and south, and the freight cost estimator prices the lane to your ZIP with the listed price before freight; on a tank this size the estimator is where the project budget starts, not a detail you check at the end. The site work is the same scale. A rotationally molded floor bears on the whole pad and on nothing else, so 137,610 pounds with plain water in it, and 261,459 pounds if the liquid works the 1.9 rating on this sheet, presses down through that 142 inch circle. There is no rule of thumb slab that carries that flat: it is engineered, level, cured, in full contact under the whole floor, and bermed where the liquid is regulated, per the concrete pad sizing guide. Above the pad, better than twenty one feet of shell needs clear height and then room over the manway for a fill line, a vent and a person, so purlins and power lines get measured before the order is cut, and the empty shell gets banded to structure or anchored into the slab on the day it lands, with the anchorage designed rather than added. Check 16,500 gallons against the draw between deliveries in the tank sizing calculator, and take the reserve and the warm weather freeboard from the tank sizing guide.

Five ways to buy 16,500 gallons

Take this molding when the liquid is denser than water and the 1.9 figure has to appear on a submittal. Everything in the top four rows comes out of the same 142 by 257 inch mold at the same volume, listed separately, each rated as its own sheet says, and the empty weights are the honest signal of how much wall each one carries: 5,600 pounds here, 5,100 pounds on the two black gradings, 3,000 pounds on the C126. There is also a lighter rated natural white tank in this identical shell, listed on its own page with its own rating and its own empty weight, and on water or a light process liquid it is the cheaper honest answer. If the roof is the constraint rather than the floor, the 3030100C26 lays 15,000 gallons across a 165 inch base at 184 inches tall; if the volume is short, the 3030000N49 takes 18,800 gallons up to 242 inches on the same wide base. Crosslinking is the other half of the decision on a wall this thick, and the crosslinked against high density polyethylene article explains what it buys in chemistry duty.

Twenty one feet of shell under an 18 inch manway

• Access height first, because on this tank it is a design problem rather than a detail: the 18 inch threaded, vented manway is at the top of a 257 inch shell. Nobody reaches that on a ladder leaned against a plastic wall. It wants a fixed caged ladder or a platform off adjacent structure, a rail and a gate at the opening, a fall arrest anchor point that is not the tank, and a permanent fill connection landed at the manway so no driver ever climbs with a hose.
• Outlet as listed: the sheet lists the outlet as 26 and gives no bottom fitting diameter, material or thread anywhere on it. We print the field as it stands and guess nothing from it. Name the liquid and the draw-off arrangement at order and we confirm what this molding takes, in what material, with what gasket, before anything is drilled.
• Fill and vent: a dip tube run to the floor, because a stream free falling better than twenty feet foams a headspace and beats up the floor; the vent piped outdoors on anything that fumes, and sized to the delivery pump rather than to the nearest port.
• Hardware as listed: ladder lugs and two flange lines. No inlet is given on this sheet.
• Service limit: 140 F / 60 C. Warranty: 3 year. Rating: specific gravity 1.9 as the sheet gives it.

Height is also what makes the hydraulics good. A column of liquid this tall gives a transfer pump more suction head than any tank in the family, so a pump mounted below the draw off runs flooded far into the tank and the last inches still move, and a low level float is what stops it before it pulls air. The same head works against the fittings: whatever leaves the tank at the base sees more pressure here than on a short tank, which is why the first valve rides on its own support off the pad and never on the wall, and why a flexible connector belongs between the tank and any hard pipe so pump vibration and thermal movement never reach the shell. Natural white passes some light, so a liquid that is degraded by light wants one of the black gradings instead; what white buys you is the ability to see the level and the condition of the liquid from outside, which on a tank this tall is worth a great deal on the day something looks wrong.

Bulk dense chemistry at plant scale

At 16,500 gallons with a 1.9 wall behind it, this is a tank that gets bought by a process engineer rather than an operator: a chemical plant holding a dense acid or brine between unit operations, a mining or minerals site storing a heavy reagent, a large municipal water plant taking coagulant by the tanker, and a fertilizer terminal holding a dense solution through a season. Water is comfortably inside the rating, but a fire reserve at this volume is its own design problem with its own sizing discipline and freeze protection, set out in the fire water reservoir design guide, and a heavy walled chemical tank is rarely the efficient answer to it. Where a plant is aggregating reclaimed streams and banding them by quality before reuse, the industrial water reuse tank topology article shows where a vessel of this size sits in the sequence and what it should and should not be asked to hold.

Out of Lincoln at class 300, and the crane is booked first

Freight leaves Lincoln, Nebraska at class 300 as the sheet lists it, as a permitted oversize move on a 142 by 257 inch piece, and the freight cost estimator prices the lane to your ZIP with the listed price before freight. Sequence the day before the truck rolls: pad cured and signed off, crane and rigging on site with the reach to stand 5,600 pounds up in one pick, straps around the body and never through the manway, anchorage hardware already set in the slab so the bands go on before the crane leaves. Commission with water to the manway, hold it, and walk the pad edge and the base of the wall for movement or a weep, then drain and dry before the process liquid arrives. Photograph the tank full on its pad on day one from the same four positions you intend to inspect from later; on a vessel this big the baseline photograph is the difference between knowing something changed and arguing about it. The first fill is the only cheap time to find a problem, so do it in daylight with someone watching the base.
