2000 Gallon 30 Degree HDPE Cone Bottom Tank in White

The heavier of the two 2,000 gallon rows, and what it buys

Start with the family, because at 2,000 gallons on a 90 inch circle there is more than one row and only two figures separate them. This listing is the 1.9 row. It carries 31,692 pounds of max contents against 16,680 pounds of water in the same 2,000 gallons, and it is listed at 400 pounds empty rather than the 325 pounds the lighter listings carry. That is the whole of the published difference, and it is the difference you buy. Work out what your liquid weighs per gallon before you compare part numbers, because that one figure decides this purchase faster than price does. If the product is no heavier than water, the 1.9 rating is wall you will never load and a lighter row is the honest buy; if the product is genuinely dense, this is the row that lets you fill the tank with product instead of with headroom. Nothing else about the two is explained on the sheet, so nothing else is explained here. The colour field reads White, which means daylight reaches the contents and an operator can read the level roughly by eye from the floor, without a ladder and without opening anything. That is worth a great deal on a tank that gets used twenty times a day and it is worth nothing at all on product that has to be kept dark. Underneath all of it sits the structure, and the structure is where cone bottom purchases go wrong. This tank has no flat floor and cannot stand on its own bottom. 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, its own price and its own lead time, and this page states no stand height, no rated load and no stand material for that reason. What the sheet does hand the structure is the load: 400 pounds of empty tank, 16,680 pounds of water and up to 31,692 pounds at the rating, all of it arriving through a handful of stand feet inside a 90 inch circle rather than spreading across a slab. Fix the volume before any concrete is poured with the tank sizing calculator, take the freeboard discipline from the tank sizing guide, and settle the support drawing before the part number is fixed.

One ninety inch circle, four rows, and a sixteen fifty underneath

Read the top four rows as one shell listed four times at 2,000 gallons on a 90 inch circle, separated by empty weight and by the name the sheet prints on each: 400 pounds here and on one other row, 325 pounds on the two lighter ones. The height is spelled two ways in this table and that is not a typing error. The dimension field on this listing gives 101.75 inches; the sibling rows give 102 inches. Both are printed where they belong and neither is rounded away, because a doorway measurement is not the place for a tidy number. The two rows underneath the group are where a real decision lives. The 1,650 gallon listing sits on an 86 inch circle at 94 inches, narrower and shorter in both directions, and it is the right answer when the batch you actually run is smaller than the round number somebody wrote into the specification. The 2,500 gallon listing sits on this same 90 inch circle at 125 inches, so it buys 500 more gallons out of height alone with no change to the footprint, the pad or the aisle. That last point is worth pausing on before the civils are drawn. Where the circle stays the same, stepping up a size later is a drawing change; where the circle changes, as it does on the 1,650, the pad, the bund and the support all change with it. Decide the circle first and the gallons second. If the angle itself is the open question rather than the size, our cone angle selection guide sets the shallow, middle and steep options against the way real product behaves on the way down.

The vent comes with the eighteen inch manway

• The vent, first, because it is the fitting whose failure costs the most: it arrives as part of the 18 inch threaded vented manway on this sheet rather than as a separately specified item. That air path is what protects the wall while a pump draws the tank down, since a shell that cannot take air in takes the load in its own wall instead. Keep it clear, look at it every time the tank is opened, and never blank, wrap or tape it to control an odour.
• The manway itself: 18 inches, threaded, sitting at the top of 101.75 inches of shell plus the height of whatever stand carries it. The lid size field on this sheet also reads 18 inches. Plan the access with the structure rather than off the shell, and land the fill at a coupling at working level instead of asking anyone to carry a hose to the top.
• The outlet: this sheet publishes no outlet field and no inlet field at all, so no discharge size, no thread, no bulkhead and no valve is stated or implied 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.
• The cone: 30 Degree is the maker's name word on this listing and the sheet carries no cone angle field, so the geometry is confirmed against the part number rather than read off a photograph. What is certain is the load path. Everything hung at the low point holds up the column above it, and the sheet allows that column to reach 31,692 pounds, so carry the valve, any reducer and the first run of pipe on steelwork off the stand rather than on the tank, with a flexible connector at the first joint.
• What the sheet does not dimension: no lug count, no flange count, no tiedown detail, no inlet, no warranty term and no NMFC number. None of them is claimed. What is published is the rating of 1.9, 16,680 pounds of water at 2,000 gallons and 31,692 pounds of max contents.
• Temperature: this sheet publishes no service temperature limit, so none is stated. Tell us the fill temperature along with the product and we will confirm it against the part number.

A white wall gives you a rough level by eye in daylight and nothing you would meter from, so if the process needs a number rather than an impression, specify the level instrument with the tank rather than after it.

Dense blends that have to leave the tank clean

Nobody pays for a 1.9 rated shell because it reads better on paper. They pay for it because the product weighs more than water and they intend to fill the tank. Concentrated mineral and salt solutions in a process building, liquid fertiliser and crop input concentrate at an agricultural retailer, treatment chemistry held at working strength, brines and spent liquor in a metals shop, and process intermediates carrying solids in suspension that still have to drain clean at the end of a run. The 31,692 pound allowance against 16,680 pounds of water is what makes those loads ordinary here rather than marginal. The cone is the second half of the argument and it is the half that pays back fastest at high specific gravity, because dense product left standing in the last inches of a flat floor is heavier, more valuable and more of a disposal problem than a light one. At 2,000 gallons a residual layer is a ticket and a contamination risk in the next batch, not a nuisance. One honest caution belongs to the shape rather than to the tank: better than eight feet of liquid on a 90 inch circle stratifies more readily than a wide shallow vessel does, so if your blend wants to separate, plan the draw point and the mixing arrangement at the same time as the tank rather than a season later. Name the liquid when you enquire and start the check yourself in our chemical compatibility reference, because the gasket and trim selection follows the chemistry and not the vessel.

Which liquids, at what concentration, with which fitting

Each entry pairs a rated liquid with its concentration limit and the fitting and gasket to order alongside the tank. The full rating sits on the linked page and in the chemical compatibility database before ordering.

Four hundred pounds on an oversize ticket out of Lincoln

This tank is moulded at Lincoln, Nebraska, and the sheet gives Nebraska as the state it ships from, which puts the plains and the Midwest on the short lane and both coasts on the long one. The freight class reads 500 beside an OVS ship mode, and no NMFC number is published. The package measures 90 inches by 90 inches by 101.75 inches at 400 pounds, which is a very large envelope carrying very little weight, and that combination is what surprises people when the quote lands: the trailer is paid for by the space, not by the scale ticket. Price the lane to your own ZIP with the freight cost estimator before you commit; the listed price is before freight. It travels lying down and is stood up at your end, so nominate the machine and the person for that job before the truck is booked rather than solving it at the tailgate. The sheet publishes no crane, no rigging, no permit and no escort detail, so none is described here; agree the offload equipment and the delivery window with us in advance. Have the support set, levelled and anchored first, because there is nowhere sensible to park a cone bottom tank while concrete cures. This sheet counts no lifting lugs, so do not assume any: sling under the body, never off the manway, and restrain the shell the moment it is upright. Commission with clean water rather than product, hold the 16,680 pound water load, then read the manway seal, the cone joint, the stand feet and the pad edge in that order and leave it standing full overnight. Because this row will hold something heavier than water, watch the stand feet again on the first full product fill; that is the load the structure has never seen. Chalk the full-water line on the outside while the tape is still out. A strap that is checked once a season is a strap that holds; put it on the same calendar as the gutters.
