Snyder Industries 1000 Gallon ASTM XLPE Black Double Wall Tank

Two plants, California and Nebraska

Two plants on one sheet is the first thing worth noticing about this part number, and on a vessel this size it is worth real money. Chowchilla, California and Lincoln, Nebraska are the moulding points and California and Nebraska the two ship-from states, and between them they put the West Coast, the Southwest, the plains and much of the Midwest within a manageable move rather than a cross country one. Compare that with the single plant products in the same range, where every mile is measured from one place. The shipping size is 81 by 81 by 69 inches at 500 pounds, class 300: nearly seven feet square and a little under six feet tall, which is a wide load on a pallet rather than a tall one, so the cost drivers are distance and deck space rather than height clearance. Price your own lane with the freight cost estimator and let the answer inform the size decision; the listed price is before freight. The wide, low proportion is also what makes this tank straightforward at the far end. Six feet to the top means the manway is reachable from a modest platform instead of a fixed ladder, a delivery coupling can be brought to working level, and the vessel goes under a roof and through a bay door that a tall vertical of the same volume would never clear. What it costs is floor. Seven feet square is real estate, and it is the constraint to check first: measure the door width and the turning room on the route to the final position, because a seven foot square object does not corner in a corridor. The base under it matters more than the tank does. Put it on a flat, continuous and level surface carrying the whole footprint, never on rails and never packed at a corner, because above that base sits 8,340 pounds of water at 8.34 pounds per gallon and 15,846 pounds at the published 1.9 rating. Confirm the slab with whoever owns the building before the order goes in rather than after the first fill. Then settle the capacity properly: run the delivery quantity and the turnover through the tank sizing calculator and take the freeboard discipline from the tank sizing guide, since on a contained vessel the volume you can use is never the volume on the label.

Three more 1000s, a 750 and an 1100

Four listings share this exact 81 by 81 by 69 inch shell at 500 pounds, differing only in the name and the color the maker assigns: two named for chemistries, two named as cross-linked or high density. The sheet explains none of it and neither does this page. Describe the product, the strength and the duty, and we will tell you which part number to order; that is a conversation, not a puzzle to solve from a table. The two rows that are genuinely different sizes show how oddly this range scales, and the 1100 is the one to study. The 750 gallon 5990902N30 sits on a 73 inch plan at 67 inches and 390 pounds, so stepping down saves a little width and almost no height, and costs a quarter of the volume: a poor trade unless the bay is exactly that tight. The 1100 gallon 5470000N48 holds only a hundred gallons more than this tank, but does it on a narrower 76 inch plan by going up to 104 inches, at 650 pounds. That is a different installation altogether: over eight and a half feet tall, so the top is a platform rather than a step, and heavier to set, in exchange for a few inches of width each way. So the choice among the three is not about gallons, it is about which dimension your room has spare. Floor and a low roof, this tank. Height and no floor, the tall one. Neither, and the 750 is the compromise with the deliveries that come with it.

A 16 inch threaded vented manway

• The fill opening: a 16 inch threaded vented manway is the only opening this sheet publishes, so it is the delivery route, the inspection route and the cleaning route at once. Sixteen inches is enough to get a proper look inside and to work a lance, and this is the one sheet in the family that gives that figure rather than a lid size.
• Reaching it: the top is at 69 inches, so a step or a modest platform serves where a taller vessel would need a fixed ladder and a fall protection arrangement designed around it. Bring the fill coupling down to working level rather than making a driver climb at every delivery.
• The vent: the manway is listed as vented, and that path protects the wall while a delivery pushes air out and while a pump draws the level down. Keep it clear, inspect it whenever the manway is opened, and never restrict it.
• The outlet: the outlet field reads 1 Manway / Lid, which names an opening and not a pipe size; no inlet, thread, flange or valve is published on this sheet, so none is claimed. Before the pump and the discharge are specified, tell us the duty and the line size and we will confirm what this part number carries.
• The space between the walls: no monitoring port, no gauge and no alarm is published, and no stand, legs or level device. Specify how that space will be watched and recorded, because on a vessel holding this much the whole value of the second barrier is the evidence that it is still empty.
• Limits: 140 F / 60 C on this sheet, a specific gravity rating of 1.9, and a 3 Year Warranty. We print the rating this product carries and do not borrow a figure from a sibling sheet.

Name the product and its strength when you order. Every wetted part on a contained tank is chosen against the chemistry, and the second wall does nothing for a fitting specified from a catalogue default.

Taking a delivery where a bund is not an option

A thousand gallons is the size at which a site stops taking drums and totes and starts taking a delivery, and the contained version is bought where that delivery has to stand somewhere a release would be expensive: a municipal water or wastewater treatment plant, a food, beverage or dairy processing line, a power station or large boiler house, a pulp, paper or metals plant, a mine site water treatment package, and industrial process lines that dose continuously between deliveries. The economics usually drive it. A thousand gallon buy is a different unit price and a different delivery frequency from a tote programme, and the second wall is what makes that change possible indoors or on a surface where a built bund would otherwise have been the answer.

Three pieces of reading are worth the time before the order. The usable volume and the real headspace are not the nameplate figure, which the double wall freeboard sizing guide works through on thermal expansion, chemistry and density. A polyethylene wall's hardest service is at the vapor line rather than under the liquid, and the wall thickness at the vapor saturated headspace guide explains what a liquid side inspection misses. Where somebody asks how the space between two walls gets tested, the cathodic disbondment testing guide for double wall interstitial spaces sets out the methodology and the polyethylene boundary. And where the site is separately planning private fire water storage, that is a different duty entirely and the fire water reservoir design guide for rural and remote sites is where that conversation starts; nothing on this page is a claim about that use.

Five hundred pounds off two lanes

Two plants, Chowchilla, California and Lincoln, Nebraska, with California and Nebraska both listed as ship-from states, so the lane that serves you is usually the shorter of two rather than the only one. Freight is LTL at class 300 with no NMFC number, and the shipping size is listed at 81 by 81 by 69 inches at 500 pounds. Price the lane to your ZIP with the freight cost estimator; the listed price is before freight. The constraint at your end is width rather than height: a pallet nearly seven feet square needs a proper door and a straight run to its final position, so measure the route before the truck is booked. Take it off under the base with forks, never with a strap round the body and never by the manway. Set it on the finished, cured, level surface in its final position before a single pipe is connected, because a tank this wide is not shuffled sideways once it is plumbed. Fill it with clean water and hold the 8,340 pound load while you read the manway seal, the base all the way round and the surface under it. Drain it, let it dry, open the space between the walls, look at it in good light and record the date on the shell. Photograph the base and the manway before the pipework goes on; a slow weep is far easier to compare against a photograph than against somebody's memory. Leave room to walk all the way around it; the side of the tank nobody can see is the side that leaks.
