Snyder Industries 11500 Gallon XLPE Cone Bottom Tank

Why the N46 listing and not the thirty-six hundred pound pair

Four part numbers hold 11,500 gallons on this sheet and they are the same 142 inch circle at the same 215 inch height, so the choice between them is not a shape choice at all. It is a rating choice, and the sheet makes it in two columns. This listing and 5340100N40 are both 2,850 pounds empty. The two heavy duty listings, 5340100N42 and 5340100N48, are both 3,600 pounds. Heavy duty is the maker's own name word for those two and the sheet offers no account of what changes inside the wall to make the difference; we print the figures it publishes and invent nothing to explain them. What you can act on is what each listing is rated to hold. This one is rated at a specific gravity of 1.5 with 143,865 pounds of max contents, which covers water, treated water and the very large family of process liquids no heavier than water. If your product is genuinely denser than water, take the listing whose rating matches it and do not ask the wall to make the argument. If it is not, a heavier rating is extra freight on the ticket and a number you will never load. The colour field is the second thing that separates these four, and it is worth a moment rather than a shrug: black is the field-standard choice for a vessel that stands outdoors in daylight, and a natural white shell is the one people pick when they want to read a level through the wall indoors. Neither changes the gallons. Settle the volume before any of it with the tank sizing calculator and take the freeboard discipline from the tank sizing guide, because on a vessel holding 95,910 pounds of water the headspace you leave is the margin you keep. Then settle what holds it up. A cone bottom tank has no flat floor and cannot stand on its own bottom, and this sheet publishes no stand, no legs, no skirt, no support ring and no bolt pattern, so the support is a separate item with its own drawing and its own lead time. No stand height, rated load or stand material appears on this page for that reason. Work it through with the cone bottom tank stand compatibility matrix and confirm the fit against this part number with us before anything is ordered. Your finished height is the stand, plus 215 inches of shell, plus clearance above the manway, and separately the room the cone needs to discharge into underneath. That is seventeen feet eleven inches of tank before a single leg is drawn, so measure from the lowest fixed thing over the spot rather than from the roof.

One circle, four names, two weights

Cover the first column and this table becomes a height ladder on one footprint, which is the most useful thing about it. The circle never changes: 142 inches across on every row, eleven feet ten inches, so the pad, the bund and the aisle you draw for one of these serves any of them. What moves is the height and the gallons. SII-5320100N43 holds 7,400 gallons at 160 inches and 1,600 pounds, which is the honest buy when the real batch is smaller than the round number somebody wrote into the specification. This tank holds 11,500 gallons at 215 inches. 7490100N49 holds 13,000 gallons at 238 inches and 3,250 pounds, buying the extra volume purely in height. In a building with a fixed roof, a crane rail or a mezzanine over the spot, that ladder is how you get the batch you need at the height the structure allows without redrawing the foundation. The four 11,500 gallon rows are the rating decision rather than the size decision, and the sheet separates them only by weight and by the name it prints on each. Two things follow from the sheer size of this vessel and both belong in the plan early. A tank of this depth is read by instrument rather than by eye, and the wrong instrument gives a confident number that is wrong all year: the level gauge selection guide for chemical service compares the technologies on their failure modes rather than their brochures. And a bulk vessel is read by people who did not order it, so settle the outside of it at the same time with the tank label and signage guide.

The vented manway on top, and the field that reads thirteen

• The manway and its vent: an 18 inch threaded vented manway is the access this sheet publishes, and the vent arrives with it rather than being specified separately. That matters more here than on a small vessel. A pump drawing from the bottom of a full column pulls hard, and a wall that cannot take air in takes the load instead. Keep the vent clear, check it whenever the tank is opened, and never blank, tape, paint or wrap it to control an odour.
• Where that work happens: the manway sits at 215 inches plus the height of the stand, which is well above head height in every installation. A platform or fixed ladder with a fall protection plan belongs in the same drawing as the structure, and the fill should land at a coupling at working level rather than asking anyone to carry a hose up there. The sheet notes ladder lugs.
• The outlet: this sheet lists the outlet as 13. That is the field value and we print it exactly as it reads. It is not a pipe size, not a thread and not a valve, and none of those is asserted here. Tell us the line size you need to land, the valve type and the product, and we will confirm what this part number carries before anything is ordered.
• Under the cone: the valve, any reducer and the first run of pipe belong on their own steelwork off the stand, never on the tank, with a flexible connector at the first joint so pump vibration stays out of the wall. With 143,865 pounds of rated contents above it, the low point of a full column is the last place to hang dead weight.
• The cone: published at 30 degrees. That keeps a free-flowing liquid moving toward one point and will hold onto material that packs or consolidates, so if your product settles hard, say so when you enquire and let us talk about geometry rather than capacity.
• What the sheet leaves blank: no inlet, no separate lid size, no warranty term and no NMFC number. The ratings it does give are a specific gravity of 1.5, 95,910 pounds of water at 11,500 gallons, 143,865 pounds of max contents, 2 flange lines and a limit of 100 F / 37 C.

Where a vessel this size stands over ground, a floor or a drain that would have to be recovered after a release, the containment question is a separate question from the tank question and deserves its own answer before a bund is poured around the wrong thing: the Captor containment comparison sets the contained polyethylene route against the alternatives.

Bulk holding where the vessel has to come back empty

At 11,500 gallons this is bulk storage rather than batch storage, and the cone is what keeps it honest. Liquid fertiliser and crop input holding at an agricultural retailer taking full truck drops, polymer and coagulant bulk supply at a water or wastewater works, process and treated water holding that still has to drain fully, blending and intermediate storage in manufacturing, and buffer volume between two stages that run at different rates. On a flat bottomed tank of this size, every product change leaves a layer on the floor that somebody has to pump, shovel or explain, and at 95,910 pounds of water even a thin heel is a disposal ticket and a contamination risk in the next load. This vessel drains toward one point at 30 degrees instead. One honest caution belongs to the shape rather than the tank: seventeen feet eleven inches of column on a 142 inch circle will stratify if the product wants to, so the draw point and the mixing arrangement deserve to be planned together rather than one after the other. Name the liquid when you enquire and check it first in our chemical compatibility reference, because the gasket and the fitting selection follow the chemistry and not the vessel.

Two thousand eight hundred and fifty pounds, class three hundred, Lincoln

This tank is moulded at Lincoln, Nebraska, and the sheet gives Nebraska as the state it ships from, so the plains and the Midwest are the short lane and either coast is the long one. The freight class reads 300, a numeric class rather than a mode, and the sheet publishes no NMFC number. It shipments at 142 inches by 142 inches by 215 inches at 2,850 pounds, which is a very large package that does not weigh much for its size, and that combination is what surprises people when the quote arrives. Price the lane to your own ZIP with the freight cost estimator; the listed price is before freight. Be honest about the width before the truck is booked, because eleven feet ten inches across is the dimension that governs the gate, the yard and the turning circle, and it strands a trailer at the entrance rather than at the dock. The sheet publishes no crane, no rigging, no permit and no escort detail, so none is stated here; agree the offload equipment and the window with us in advance instead of assuming a machine will be free on the day. Have the stand set, levelled and anchored before the trailer arrives, because there is nowhere sensible to park a cone bottom tank this size while a foundation is finished. It travels lying down and is stood up at your end. Lift under the body with slings, never by the manway, and keep it restrained from the moment it is upright, because a shell this tall takes wind at a speed nobody expects from an empty tank. Then prove the whole installation with clean water rather than product: hold the 95,910 pound load, read the manway seal, the cone joint, the stand feet and the pad edge in that order, and leave it standing full overnight. Walk the pad again after the first hard rain. Ground that was uniform when it was dry rarely stays that way under a load this concentrated, and the edge of the pad is where it shows first. Save the pallet; a tank that ever has to move again is easier to move on it.
