A 1600 gallon cone on an 88 inch circle, 560 lb empty
This is a Norwesco 1600 Gallon Light Blue Heavy Duty Cone Bottom Tank. The sheet gives the shell as 88 by 88 inches on plan and 84 inches tall, with the diameter cell reading 88 inches, which is seven feet four across and seven feet from the base to the rim. Empty weight reads 560 lb and the ship weight cell repeats that same 560 lb. The colour cell reads Light Blue and the material cell reads Polyethylene. The grade line reads 1.9 against a maximum contents weight of 25354 lb; the same 1600 gallons in water at 8.34 lb per gallon comes to 13344 lb. The outlet cell reads a 2 inch PP female NPT bulkhead fitting and access is a 16 inch threaded vented manway. The maximum temperature cell reads 120 F / 48 C, the warranty cell reads a 3 Year Warranty, and the freight class cell reads 400.

40819 and the three rows beside it
| Part | Gallons | Shell, inches | Empty weight |
|---|---|---|---|
| 40819, this record | 1600 | 88 x 88 x 84 | 560 lb |
| N-40817 | 1600 | 88 x 88 x 84 | 239 lb |
| N-43854 | 1500 | 72 x 72 x 112 | 332 lb |
| N-44337 | 1720 | 78 tall |
The second row carries the same 1600 gallons in the same 88 by 88 by 84 shell under a different part number, and its weight cell reads 239 lb where this one reads 560 lb. Both readings are printed here exactly as the sheet has them; nothing on this page works out what stands behind the two figures, because that is not something the sheet says and it is not something we are prepared to invent. If the distinction matters to your order, name the part number and our team will confirm against it. The other two rows change the geometry rather than the volume: 72 inches on plan and 112 tall is a narrower, much taller building, and the bottom row publishes only a height with no plan dimension and no weight, so its cells stay blank here rather than borrowing from a neighbour. For choosing between cone geometries generally, the cone bottom buyer's guide to the 15, 30 and 45 degree options is the place to start, with a dedicated guide at the 1600 gallon size and a companion piece covering the same capacity supplied on a poly stand.

What the plumbing cells say, in full
- Draw point
- A 2 inch PP female NPT bulkhead fitting. Polypropylene body, female thread, through the wall. On a cone bottom the draw point is the whole reason for the shape, so plan the valve and the receiving vessel to the fitting rather than the other way round, and give the first joint its own support within a foot of the shell so the bulkhead carries liquid and not steel.
- Top opening
- A 16 inch threaded vented manway. The inlet cell is a dash, so this opening is the only way in that the sheet describes and filling happens through it.
- Service ceiling
- 120 F / 48 C, a limit on the contents rather than a target.
- Weight cells
- A grade line of 1.9 against 25354 lb of maximum contents, with 13344 lb as the water case.
- Cells left empty
- The structural cell publishes nothing and the cone angle cell is blank, so the angle appears in the product name and nowhere in the data.
The limitation to be straight about is that one bulkhead is the entire published plumbing arrangement: no second boss, no gauge port, no vent line connection and no dedicated fill. Anything beyond that single draw point is an addition you plan for yourself.
The site question for a cone is what holds it up
A cone bottom has no floor to stand on, so the first site decision is not the pad but the structure, and this record does not publish one. No stand, cradle, ring or frame appears in its cells, and there is no load figure, leg count, height or anchor detail anywhere on the sheet to quote you. We will not make one up. What the sheet does give you to work with is the load the support will see, 13344 lb of water plus 560 lb of tank over an 88 inch circle, and the shape it has to accept. Our cone bottom tank stand compatibility matrix is the right document to work through before you order either half of the assembly. Whatever ends up underneath it, the ground under that still has to be flat, level and continuous, because a cone that sits off plumb drains toward one side of the discharge rather than through it, and the residue you were trying to avoid comes straight back. For clearance, plan on the 84 inches of shell plus the height of the support plus standing room at the 16 inch manway, and leave real space beneath the outlet for a valve, a union and whatever is catching what comes out. Size the volume itself with the tank sizing calculator and the tank sizing guide before you commit to the footprint.
Batches that have to come out clean
The argument for a sloping floor is always the same and it is a good one: a flat bottomed tank keeps a heel, and everything that settles or separates ends up sitting in it. A cone puts the entire floor on a slope and gathers it at one point, so the tank drains itself, rinses with less water and gives you back the time somebody would otherwise spend inside it with a hose. That is why cone bottoms end up in mixing and batching duty, in operations that change contents between runs, and wherever the material carries solids that would otherwise build up. At 1600 gallons on a seven foot four circle this record is well into the size where hand-cleaning a flat floor stops being realistic and the geometry starts paying for itself. The trade is the one the previous section describes: you buy the structure separately and you give up floor level access to the discharge. Check any candidate contents against the two cells that govern it, the grade line of 1.9 and the 25354 lb maximum contents figure, before the conversation gets as far as fittings.

Three plants, three states, and the rim check
This record prints three plants, Lancaster in Ohio, Tooele in Utah and Hanford in California, and the ship-from cell names California, Ohio and Utah to match. Three origins spread east, west and mountain usually means a shorter lane than a single-origin item, which matters on a shell that prices on its cube rather than on its 560 lb. Ship mode reads LTL and the freight class cell reads 400. The listed price is before freight; put your ZIP into the freight cost estimator and the system will pick the lane. The receiving check on a cone is different from the one you would do on a flat bottomed tank, and it takes a straightedge: lay it across the 88 inch rim in two directions and confirm the rim is still round and flat, because a cone rides in a cradle that holds it by the rim and an out-of-round rim is exactly the thing that turns into a fight when the tank has to sit down square in its support. Do that on the deck. Once the tank is in the structure and full of product, nobody is going to want to hear about it. Check the strap tension a week after the first fill; a tank settles a little, and the strap that was tight is loose.
