2000 Gallon 30 Degree Plastic Cone Bottom Tank in White

Why the lighter rating is the honest buy for water weight product

The family question comes first, because the sheet lists several part numbers on one 2,000 gallon shell and separates them by two figures only: the empty weight and the specific gravity rating. This listing is the 325 pound row at 1.5, with 25,020 pounds of max contents against 16,680 pounds of water in the same 2,000 gallons. That covers water, treated water, rinse water, and the broad run of process liquid no heavier than water, which is most real cone bottom duty. There is a heavier listing on the same shell at 400 pounds for genuinely dense product, and the sheet explains the weight difference no further than the figure itself, so neither does this page. Buying above your own duty buys nothing you can use; buying below it is not a saving at all. Get your liquid's weight per gallon in front of you and the row chooses itself. The colour field reads White, and on a working tank that translucent wall is the small daily convenience that earns its keep: an operator standing on the floor can see roughly where the level sits in daylight without a ladder, without an instrument and without opening the lid. What it costs you is light control, which matters outdoors on water-based product that will grow something in a translucent shell and matters not at all in a dark plant room. That is the whole of the published difference between the rows, and nothing further is invented for it. Then the structure, which is the part that gets under-built on a cone. This tank has no flat floor and cannot rest on its own bottom, and the sheet publishes no stand, no legs, no skirt, no support ring and no bolt pattern, so the support is a separate item and no stand height, rated load or material is stated here. It has to carry 325 pounds of empty tank, 16,680 pounds of water and up to 25,020 pounds at the rating through a few feet inside a 90 inch circle rather than across a slab, with 101.75 inches of shell standing above it. Leave clearance under the cone for whatever the discharge feeds, because clearance below is what a cone is for and it is the first thing a tight building takes away. Size the volume with the tank sizing calculator and take the freeboard from the tank sizing guide before either the tank or the support is ordered.

Four listings at two thousand gallons, a smaller circle and a taller shell

Cover the part numbers and the top four rows stop being four tanks. They are one 2,000 gallon shell on a 90 inch circle, listed several ways and separated by the weight and the name printed on each. Three rows sit at 325 pounds and one at 400 pounds; that is what the sheet gives and this page adds nothing to it. The bottom two rows are the size ladder and they behave differently from one another. The 1,650 gallon listing is on an 86 inch circle at 94 inches, so it is smaller in plan and in height at once, and it is the row to read when the real batch is smaller than the specification says. The 2,500 gallon listing is on this same 90 inch circle at 125 inches, which buys 500 more gallons out of headroom alone. Because the circle does not change across those two, the pad, the bund and the aisle can be drawn once and the capacity decided later; that is worth knowing before concrete is specified rather than after it has cured. Measure the headroom now even if today's duty is settled, because the option to grow is free while the drawing is still open. For the long read on a taller cone bottom tank in this colour, our complete buyer's guide to the natural white cone bottom tank a size class up walks the whole selection rather than one part number, and most of what it says about supports, access and drainage applies straight down the ladder.

An eighteen inch threaded vented manway and a published service limit

• The vent and the lid arrive together: the sheet gives an 18 inch threaded vented manway, with the vent part of it rather than a separate line item, and the lid size field also reads 18 inches. On a vessel being pumped down that air path is doing a structural job while looking like a convenience, so keep it clear, inspect it whenever the tank is open, and never blank or tape it.
• Getting to it: the manway sits at the top of 101.75 inches of shell plus whatever stand carries the tank. This sheet counts no ladder lugs and no structural attachments at all, so the access arrangement belongs to the structure and not to the shell, and the fill line belongs at a coupling at working level.
• The service limit: 100 F / 37 C is published on this sheet, which is a real number rather than a formality. A hot rinse, a heated make-up line or summer sun on a full vessel is exactly where it stops being theoretical, so give us the fill temperature along with the product.
• The outlet: this sheet publishes no outlet field and no inlet field, so no discharge size, thread, bulkhead or valve is stated anywhere on this page. Give us the line size you need to land, the valve type and the product and we will confirm what this part number carries before it ships.
• Below the cone: 30 Degree is the maker's name word and this sheet carries no cone angle field, so no measured angle is claimed. What does not change is the load path. Everything at the low point holds up the column above it, up to 25,020 pounds at the rating, so support the valve, any reducer and the first pipe run on steelwork off the stand rather than on the tank, with a flexible connector at the first joint so pump vibration stops there.
• Not published on this sheet: a warranty term, an NMFC number, a lug count, a flange count and any stand detail. None is claimed. Published: a rating of 1.5, 16,680 pounds of water at 2,000 gallons, 25,020 pounds of max contents and a limit of 100 F / 37 C.

Mark the vent and the fill on the outside of the shell once it is standing, because the one job nobody should be doing by torchlight is working out which opening is which.

Make-up and rinse duty where the vessel turns over daily

Two thousand gallons with a full-drain bottom belongs to operations that empty the same vessel on a schedule rather than filling it once a season. Polymer and coagulant make-up at a water or wastewater works, liquid fertiliser and crop input blending at an agricultural retailer, batch preparation and intermediate holding in manufacturing, wash and rinse systems that are emptied between runs, recovered process water waiting on a decision, and day tank duty feeding a pump at a steady rate off a useful reserve. What ties them together is the changeover rather than the run, and the changeover is where the shape earns its price: the vessel keeps draining toward one point instead of leaving a ring of product on a floor to be pumped, shovelled or explained. The 1.5 rating matches that work honestly, since almost everything on that list is at or below the weight of water and 25,020 pounds of max contents against 16,680 pounds of water leaves real margin without paying for wall you cannot load. The white shell adds the daily convenience of a rough level by eye, which on a make-up tank being checked between batches is used far more often than any instrument. The honest limits are worth stating plainly: the published service limit is 100 F / 37 C, daylight reaches the contents through a translucent wall, and a tall narrow column stratifies more readily than a wide shallow one. Check the liquid in our chemical compatibility reference before the gaskets and valves are chosen, because the chemistry decides the trim and the vessel does not.

Three hundred and twenty-five pounds, class five hundred, Nebraska origin

Lincoln, Nebraska is where this one is moulded, and the sheet gives Nebraska as the state it ships from, so the Midwest and the plains are the short lane and both coasts are the long one. The freight class reads 500 beside an OVS ship mode, and the sheet publishes no NMFC number. The package measures 90 inches by 90 inches by 101.75 inches at 325 pounds, which is a large envelope around a light load, and on goods like this the lane can matter as much as the tank. Run your own ZIP through the freight cost estimator before you commit; the listed price is before freight. It arrives lying down and is stood up at your end, and a 90 inch circle needs a wider clear turning area on the ground than people allow for, so clear it before the truck is booked. The sheet publishes no crane, no rigging, no permit and no escort detail, and none is described here; settle the offload equipment and the window with us in advance rather than assuming a forklift will cover it. Have the support set, levelled and anchored before delivery, because a cone bottom tank with nowhere to stand is a tank lying in the yard occupying the space you needed for something else. No lifting lugs are counted on this sheet, so sling under the body and never off the manway, and keep the shell restrained from the moment it is vertical. Prove the installation with clean water rather than product: hold the 16,680 pound water load, read the manway seal, the cone joint, the stand feet and the ground at the pad edge in that order, and leave it standing full overnight. Then check the anchor bolts again a week later, because new ground settles under a new load and the fixing that was tight on day one is the one that is loose on day eight. Walk the base after the first hard rain; a pad that shifts shows it at the edge first.
