Snyder Industries 11500 Gallon 30 Degree HDPE Cone Bottom Tank in White

An oversize load out of Lincoln, and what that lane costs you

Start with the truck, because on a tank this size the truck decides the project. The sheet lists the freight as OVS, which is a mode and not a numeric class, out of Lincoln, Nebraska, with Nebraska given as the shipping state. Shipped it is 215 inches long by 142 inches wide by 142 inches high. One hundred and forty-two inches of width is wider than a standard trailer bed, and that single number is what turns a delivery into a permitted oversize move with a route, a schedule and a set of rules about when it can travel. None of that is a problem; all of it is a lead time. The sites that get this wrong are the ones that order the tank and then discover the yard gate, the last hundred yards of track, the overhead line or the turn into the compound will not take a load 142 inches wide. Walk that route before the order with a tape and a photograph of every pinch point, and price the lane to your ZIP with the freight cost estimator so the number is on the table from the start; the listed price is before freight. The second thing the lane forces you to settle early is the unload. Three thousand six hundred pounds empty is a crane or a large forklift with the reach to take a 214.5 inch tall vessel off a trailer and set it down under control, and that machine has to be booked for the delivery window rather than found on the day. Then there is what it stands on, and here the sheet is silent in a way that matters: it publishes no stand. A 30 degree cone bottom has no flat base to sit on, so the vessel is carried in a stand or a structure, and that structure is a separate engineered purchase sized to the loaded weight, not an afterthought. Tell us the duty and we will take the stand question properly rather than guess a part. The foundation under the stand is the next question, and on a poured pad rather than an engineered footing the tank sizing calculator and the tank sizing guide will get your volume and freeboard right while the civil work gets sized by somebody looking at the actual loads.

Five 11,500 gallon listings and the 13,000 above them

Four listings in this table hold 11,500 gallons on the same 142 inch diameter, at 3,600, 3,600, 2,850 and 2,850 pounds. The sheet gives those weights and explains nothing about them, so we print what it says and leave the reasoning alone. What is worth saying out loud is the practical consequence: if your site already runs one of these, order the part number you already have, so the manway, the gasket and the stand you own carry straight across. This tank is one of the two heaviest listings in that group. The genuinely different rows are the last two. SII-5320100N43 holds 7,400 gallons on the identical 142 inch diameter at 160 inches tall and 1,600 pounds, which is the tank to buy when the building, the bund or the crane reach caps your height: same floor circle, considerably less to lift, considerably less liquid. 7490100N49 goes the other way at 13,000 gallons, again on 142 inches of diameter, standing 238 inches and weighing 3,250 pounds. That is the cleanest comparison in the whole table, because all three tanks take exactly the same circle of ground and the only thing you are actually buying with the extra volume is height. Decide against the ceiling, the crane, the stand and the bund, in that order, and the choice between them usually makes itself. Where a process wants two vessels rather than one large one, say so early; two 7,400s and one 13,000 are very different projects on the civil side.

An 18 inch vented manway, and the fittings the sheet leaves out

• The fill opening: an 18 inch threaded vented manway at the top, which is the only opening this sheet publishes. Eighteen inches is a proper working access, taking a fill line, a dip, a lance and an arm, and on a vessel 214.5 inches tall it is reached from a platform or a ladder cage rather than from the ground. Plan the access with the stand, not after it.
• The vent in that manway: the manway is listed as vented, and on a tank this size the vent path is the single most important thing to keep clear. A large vessel being filled or drawn down moves a great deal of air, and a blocked vent is the mechanism behind most polyethylene tank failures that look mysterious afterwards.
• The outlet: this sheet publishes no outlet and no inlet, so no size, no position and no bulkhead is stated here. On a cone bottom the discharge arrangement is designed with the stand, the valve and the pump together, so tell us the duty and the fluid and we will specify it against the tank rather than print a fitting the sheet does not carry.
• The stand: no stand, no stand height and no cone dimension beyond the 30 degrees in the name appears on this sheet. A stand for an 11,500 gallon cone is an engineered item bought for the loaded weight, and we will not attach a part number to it here.
• Support for everything downstream: the valve, the pump, the meter and the pipework stand on their own steel. A polyethylene wall carries liquid, not hardware, and at this scale that rule is not negotiable.
• Limits and term: 120 F / 48 C, a specific gravity rating of 1.9, and a 3 Year Warranty. That is the whole of what this sheet publishes as limits, and this page claims nothing beyond it.

Name the fluid when you order, because at 182,229 pounds of rated contents the gasket, the valve body and the fitting material are not details. Where the vessel is going to hold a regulated product and somebody has asked what a contained arrangement is actually worth against the steel alternative, the contained polyethylene versus steel comparison argues it on the terms that decide it rather than on a slogan.

Settled solids, batch chemistry and a bottom that empties

Nobody buys a cone bottom for the storage. They buy it for the discharge. At 11,500 gallons the duties are process rather than warehouse: batch chemistry at a plant that mixes and then draws the whole batch off, agricultural liquid fertiliser and crop protection blending where settled product has to be recovered rather than stirred forever, mining and mineral processing where solids report to the bottom, food and beverage processing where a vessel must empty completely between products, municipal and industrial treatment where sludge or polymer is thickened and drawn off, and any duty where a flat-bottomed tank means a person with a hose at the end of every campaign. The reason to get the angle right is the same in all of them: the slope is what decides whether your specific material actually reports to the outlet or sits on the wall. That is a material question, not a marketing one, and the cone bottom angle selection guide works through the shallow, medium and steep options against what is being stored. Read it before you commit the civil work, because the stand and the foundation are sized around the tank you choose and neither is cheap to change afterwards.

Three thousand six hundred pounds on an oversize trailer

This tank is moulded at Lincoln, Nebraska, which puts the plains, the upper Midwest and the corn belt on a short lane and everywhere else on a planned one. Get the lane priced to your ZIP with the freight cost estimator before anything else is committed, and remember the listed price is before freight. At 3,600 pounds empty the unload is a crane or a heavy forklift with genuine reach, rigged under the body and never around the cone or through the manway. Have the stand set, levelled and signed off before the tank arrives, because there is nowhere sensible to put an 11,500 gallon cone on the ground while you finish the steelwork. Once it is seated, fill it with clean water in stages and walk the stand, the seat and the discharge joints at each stage rather than only at the top. A vessel this size tells you everything it is going to tell you during the first water fill, and water is the cheapest liquid you will ever put in it. Keep the first delivery's paperwork with the tank; strength and date on day one is the baseline for every batch after.
