Snyder Industries 120 Gallon ASTM XLPE Black Double Wall Tank

One plant, one state, and a small shipment

The freight story on this one is about as simple as a contained tank gets, and that is the point of the size. Marked Tree, Arkansas is the only plant on this sheet and Arkansas the only ship-from state, so the mid-South and the eastern plains are short lanes and everything else is a distance calculation rather than a special arrangement. The shipping size is 34 by 34 by 51 inches at 100 pounds, class 250 with no NMFC number: one pallet position, well inside a tail lift delivery, and light enough that the equipment at your end is a pallet truck rather than anything hired in. Price your own lane with the freight cost estimator before you compare it against the size above, because between two tanks that both ship as one pallet the freight difference is usually small and the capacity difference is not. Four feet three inches of height is what makes this the easiest tank in the family to get into a building. It goes under low steel, under a mezzanine and beneath overhead services with room to spare; on a pallet it is still short enough to clear a shutter that a taller vessel would catch; and a 96 inch ceiling is never the constraint. The only real dimension to watch is the width, because 34 inches of shipment through a 36 inch doorway is a measured job and not a casual one. Walk the route with a tape and check the narrowest point rather than the entrance. Where it lands, the base wants a flat, continuous and level surface across the whole footprint, no rails, no timber left underneath and no shim at a corner, since above it sits 1,001 pounds of water at 8.34 pounds per gallon and 1,902 pounds at the published 1.9 rating. That is within an ordinary plant room floor and well outside what a bench or a shelf was built for, so anything other than the ground needs a proper support calculation. The last thing to settle before the order is whether 120 gallons is genuinely your number. Run the consumption and the delivery quantity through the tank sizing calculator and take the freeboard discipline from the tank sizing guide; at this end of the range the deciding question is how often a truck will come, not how much space is free.

Three 120s, an 80 and a 150

Four listings share this exact 34 by 34 by 51 inch shell at 100 pounds and differ only in the name and the color the maker gives them: two named as cross-linked or high density, one named for sodium hypochlorite, and this one. What those names imply is not set out on the sheet, and this page offers no interpretation, because a product name is not a specification. Describe what you are storing and at what strength and the part number follows from that conversation. The two other rows are the genuine alternatives and they pull in opposite directions. The 80 gallon 5991002N48 is the only square listing here and the smallest footprint in this part of the family at 24 inches by 24 inches and 43 inches tall, listed at 80 pounds. It is the tank for a cupboard, a cabinet or a corner that will not take three feet, and it costs you a third of the volume to get there. The 150 gallon 5710102N30 keeps the identical 34 inch plan and simply stands taller at 62 inches and 110 pounds, so stepping up is a pure height decision with no floor consequence at all: same bay, same bund, same pallet, more gallons between deliveries. That is the comparison worth making. If the ceiling has room and the delivery is the same truck either way, the taller row is usually the better value, and this 120 is the one to buy when the height above the tank is genuinely spoken for.

The lid at 51 inches, reached from the floor

• The fill opening: a 14 inch threaded vented lid, and it is the only opening this sheet publishes. What makes it work on this tank is the height: at 51 inches the lid is at waist to chest level, so a delivery can be connected, a lance worked and the inside checked with both feet on the floor and no step at all.
• The vent: the lid is listed as vented, and that path is the wall's protection when a delivery pushes air out and when a pump draws the level down. Keep it clear and look at it every time the lid comes off.
• The outlet: the outlet field reads 1 Manway / Lid, which names an opening and not a pipe size. No inlet, thread, flange or valve appears on this sheet, so none is claimed. Tell us the duty and the line size and we will confirm what this part number carries before anything is ordered.
• Pump arrangement: with the published route in and out at the top, the usual arrangement here is a suction line and strainer dropped through the lid to a metering pump beside the tank. Keep the suction short, set the strainer clear of the bottom so the settled last inch is not the first thing it lifts, and clamp the hose to its own support rather than to the lid rim.
• The space between the walls: no monitoring port, gauge or alarm is published, and no stand, legs or level device either. The arrangement for watching that space is specified separately, and it is the part of a contained tank worth a written procedure.
• Limits: 120 F / 48 C, a specific gravity rating of 1.9, and a 3 Year Warranty.

Tell us the product and its strength at order time. On a tank this size the lid seal and the suction fitting are very nearly the whole wetted system, and choosing them generically is the mistake that shows up first.

Feed points where a drum was the alternative

A hundred and twenty gallons with containment is bought where the working quantity is modest and the consequence of a spill is not: a metering pump station on a treatment skid, a chemical feed point in a boiler house or cooling tower plant room, a small municipal or package water plant, a pool and aquatics room, a laundry or vehicle wash dosing cabinet, a plating or finishing bench, and pilot lines that have outgrown drums. The honest comparison is with a pair of drums in a tray. Drums are cheaper on day one and worse on every day after: they have to be moved to be emptied, the tray collects whatever else lands in it, and nobody can say when it was last checked. A purpose made contained vessel stays put, takes a hose, and gives you a space to inspect and a date to write down.

Two pieces of engineering are worth reading alongside the decision. The volume you can actually use is not the nameplate figure once thermal expansion, chemistry and density are accounted for, and the double wall freeboard sizing guide works that through. A polyethylene wall's hardest service is at the vapor line rather than below the liquid, which the wall thickness at the vapor saturated headspace guide explains in the detail an operator needs. And where somebody asks how the space between two walls is tested, the cathodic disbondment testing guide for double wall interstitial spaces covers the methodology and the polyethylene boundary condition.

A hundred pounds and a four foot shipment

Marked Tree, Arkansas is the plant and Arkansas the only ship-from state. Freight is LTL at class 250 with no NMFC number, and the shipping size is given at 34 by 34 by 51 inches at 100 pounds. Price the lane to your ZIP with the freight cost estimator; the listed price is before freight. This is the least demanding delivery in the mid range: one pallet position, a hundred pounds, a tail lift on most lanes, and a shipment short enough that no lintel on the route is likely to be an issue. Take it under the base, never by the lid. Set it on the finished, level surface in its final position before anything is connected, then fill it with clean water and hold that 1,001 pound load while you read the lid seal and the base all the way round. Drain it, dry it, open the space between the walls and record the date on the shell. Then write the part number on the maintenance log the day it lands; on a site running several of these at different feed points, the log is the only thing that tells you which shell is which. Put the tank's part number on the maintenance log the day it lands; five years on, nobody remembers which shell it is.
