Snyder Industries 3000 Gallon Heavy Duty Cone Bottom Tank

Ten feet of tank, and the room left above the manway

Where this one goes is settled by a tape measure held vertically, and the answer usually comes out better than people expect. The shell is 120 inches, ten feet, which is short for 3,000 gallons, and it is short because the tank is wide: 95 inches across instead of the 90 inch circle the taller listings in this family use. Under all of it goes a stand, because a cone bottom vessel has no flat floor and cannot rest on its own bottom. This sheet publishes no stand, no legs, no skirt, no ring and no bolt pattern, so the support is a separate purchase and no stand height, rated load or stand material appears on this page. Work it through with the stand compatibility matrix, which sets the makers side by side, and ask us to confirm the fit against this part number rather than taking a dimension off a photograph. Then do the arithmetic in the room you actually have. Your finished height is the stand, plus 120 inches of shell, plus the clearance a person needs to open an 18 inch manway and a fill line needs to turn into it. Subtract from the lowest fixed obstruction over the spot, not from the ceiling, and what is left is the stand you can have. Underneath, you also have to leave the cone somewhere to discharge into, and that clearance is the first thing a short building takes away. The pad carries 709 pounds of empty tank, 25,020 pounds of water and 47,538 pounds at the rating, concentrated into stand feet inside a 95 inch circle rather than spread over a slab. Designed bearing area at each foot, level and uniform, is what that needs. The wider circle helps here, because feet further apart carry less each, and it is one of the quiet advantages of a squat shell. Size the volume before the structure with the tank sizing calculator and take the freeboard from the tank sizing guide.

Same gallons, shorter shell: reading this family by height

Cover the gallons column and the table stops being about capacity. Four rows hold 3,000 gallons and they do it in two different shapes: this tank on a 95 inch circle at 120 inches, and three listings on a 90 inch circle at 144 inches. Two feet of height is the whole difference, and in a building with a fixed roof, a crane rail or a mezzanine over the spot, two feet is not a detail. That is the first reason to take this listing over the taller ones. The second is the rating. At a specific gravity rating of 1.9 with 47,538 pounds of max contents, this is the listing for a product denser than water, and the taller 90 inch listings carry their own figures for their own duties. The sheet separates the three 144 inch tanks by empty weight and by the name it prints, 500 pounds on two of them and 670 pounds on the heavy duty one, and it explains none of that; we print what it says. Below and above the capacity sit two more choices. 5100000N40 holds 2,600 gallons at 139 inches, which is the honest option when the real batch is smaller than the round number. 8050000N40 holds 3,600 gallons on a 102 inch circle at 125 inches and 1,090 pounds, wider again and heavier, for the operation with floor to spare. If you are working through this decision properly, both of these are worth the longer read: the complete buyer's guide at this capacity with a shallower cone and the guide to the natural white 30 degree shell.

What the bottom of this tank is, and what the sheet calls it

• The outlet field: it reads 1 Manway / Lid. That is the field value, it names an opening rather than a discharge, and we print it exactly as it reads. No outlet size, no thread, no bulkhead and no valve is published or claimed on this page. Give us the line size, the valve type and the product and we will confirm what this part number carries before it is ordered.
• The cone angle: this sheet publishes none, and the product name does not carry one either. We are not going to read an angle off a photograph or borrow one from a neighbouring listing. If drainage behaviour is what decides your purchase, ask and we will confirm the geometry against the part number.
• Under the cone: the valve, any reducer and the first length of pipe belong on steelwork off the stand and never on the tank, with a flexible connector at the first joint. At 47,538 pounds of rated contents the static head at the low point of a full column is unforgiving of a hanging valve.
• The manway: 18 inches, threaded and vented, sitting at 120 inches plus the stand. That is above head height in any installation, so a platform or a fixed ladder with a fall protection plan belongs in the same drawing as the structure. Bring the fill to a coupling at working level instead of asking anyone to carry a hose up there.
• The vent: it arrives with the manway on this sheet rather than as a separate item. On a tank being drawn down by pump, the air path is the wall's protection. Check it whenever the tank is opened, and never blank or tape it.
• Structural detail and blanks: the sheet notes 2 flange lines and nothing else, and it publishes no inlet, no warranty term and no NMFC number. Ratings are a specific gravity of 1.9, 25,020 pounds of water at 3,000 gallons, 47,538 pounds of max contents and 100 F / 37 C.

Where this vessel sits over ground or a floor that would have to be recovered after a release, the containment design is its own question and worth starting properly: the Captor containment comparison sets the contained route against the alternatives before you pour a bund around the wrong thing.

Heavier than water, and it still has to drain to a point

The 1.9 rating narrows the buyer list to operations holding something denser than water, and the squat shell narrows it again to the ones with a ceiling they cannot argue with. Concentrated mineral and salt solutions in a process building, heavy liquid fertiliser and crop input blends at an agricultural retailer, thickened sludge and dewatering feed at a treatment works, spent liquor and pickling solution in a metals plant, wash plant and mineral slurry duty, and process intermediates that carry solids in suspension and still have to drain completely between batches. The cone is what makes each of those work, because nothing settles into a corner the vessel cannot reach. A wide shell adds one more thing worth knowing: a squat vessel stratifies less readily than a tall slender one, so a product that wants to separate is easier to keep honest in this shape than in the 144 inch tanks listed beside it. That is a real operating advantage and it costs floor area, which is the trade to weigh against your own site plan. Start from the chemistry rather than the shape, and check the product in our chemical compatibility reference before a gasket or a valve is chosen.

Seven hundred and nine pounds, class 300, California moulding

This tank is moulded at Chowchilla, California, and the sheet gives California as the state it ships from, which is the opposite corner of the country from most of the cone bottom tanks in this family. That single fact can decide the purchase for a western buyer and can cost a Midwestern one, so price the lane before the shape argument is settled. The freight class reads 300, a numeric class rather than a mode, and the sheet publishes no NMFC number. It shipments at 95 inches by 95 inches by 120 inches at 709 pounds. Run your own ZIP through the freight cost estimator; the listed price is before freight. The shipment travels lying down and is stood up at your site, and a wide shell wants a clear circle of ground to be turned in rather than a corner. The sheet publishes no crane, no rigging, no permit and no escort detail, so this page states none; agree the offload equipment and the window with us before the truck is booked. Have the stand set, levelled and anchored before the trailer arrives. Sling under the body, never by the manway, and keep the tank restrained from the moment it stands upright. Prove the installation with clean water before any product goes near it: hold the 25,020 pound load, walk the manway seal, the cone joint and the stand feet with a torch, and leave it standing full overnight. Walk the pad again after the first hard rain, because a new load settles the ground under it and the edge of the pad is where that shows first. Keep the shipment paperwork with the site file; the next person to service this tank will not have the box. Chalk the full-water line on the outside after the first fill; it is the level every later reading gets checked against.
