Snyder Industries 3600 Gallon 15 Degree XLPE Cone Bottom Tank in White

The stand carries the cone and the pad carries the stand

Nothing about siting a cone bottom tank resembles siting a flat-bottom one, so take the ground first. A 15 degree cone means the bottom of the vessel is a shallow funnel, and a funnel cannot rest on a slab; the tank is carried on a stand, and the stand carries every pound into a small number of bearing points rather than spreading it over a 102 inch circle. That changes the civil work completely. The load is 30,024 pounds of water when full and 57,046 pounds at the sheet's own rating, all of it arriving through the stand's feet, so the slab is engineered for point loads and the anchors are set before the tank is stood up, not improvised after. This sheet publishes no stand height, no leg count, no foot pattern and no anchor size, so this page invents none; tell us the room and we will get the drawing for this part number rather than describe a frame we have not been given. What the shape buys is a floor that empties itself. Product that settles in a flat-bottom tank sits there until somebody goes in after it; in a cone it slides toward one low point and leaves through it, which is why batching, blending and any duty with solids in suspension ends up on a cone bottom. Height is the price. At 135 inches the tank alone is eleven feet three inches before the stand under it is counted, so the building, the door and the overhead services have to be confirmed against the real total before the order, and the manway at the top of it needs fixed access with a rail rather than a ladder somebody carries in. Confirm the volume is the right one for the batch you actually run in the tank sizing calculator, take the freeboard from the tank sizing guide, and read the cone bottom buyers guide, which compares the 15 degree cone against steeper ones on exactly the ground that decides this purchase: how well the product moves and how much height the angle costs you.

One 135 inch shell against the 125 inch ones

Four parts on this sheet hold 3600 gallons on the same 102 inch base and they are not listed alike. This one is given as 135 inches tall and 300 pounds empty; the other three are given as 125 inches and 1090 pounds. Both figures come from the same sheet, we print what it says, and we will confirm the shipping and empty weights for the exact part number on your order before it moves, because a ten inch difference in height and that difference in weight are worth settling in writing rather than on a web page. What the table does decide cleanly is footprint against height. The two 90 inch base parts buy their gallons upward: the 3000 gallon 5150000N40 stands 144 inches for 3000 gallons, and the 3900 gallon 5440000N40 stands 180 inches, fifteen feet, which is a serious building. If your constraint is the roof, the 102 inch base parts are the family to shop in; if it is floor space, the 90 inch base is a foot narrower and costs you height. Choose the colour by exposure rather than by preference: the black part number is the one people take where daylight on the contents is the problem, and this one is white. Whichever you take, the cone angle is chosen on how your product behaves, and that argument sits in the buyers guide rather than in a price list.

Everything leaves through the bottom of the cone

• The valve at the low point: the whole vessel drains through one fitting at the tip of the cone, and this sheet publishes no outlet size, so we print none and confirm it against the drawing for your part number before it ships. What matters more than the size is what hangs off it: a full-bore valve at the cone, then a union or a flange immediately downstream so the valve can be changed without touching the tank fitting.
• Support the pipework, not the tank: everything below the cone rides on its own stands off the floor, with a flexible connector at the first joint. A cone bottom tank on a stand moves as it fills and as the temperature swings, and a rigid line clamped to a wall takes that movement into the fitting at the one point you cannot afford to lose.
• Discharge rate and solids: a 15 degree cone is the shallow end of the range, so free-draining liquids leave it cleanly while heavier settled material needs the valve opened fully rather than cracked, and needs the line below it kept short and straight. If your product cakes rather than settles, the steeper cones in the buyers guide are the honest answer.
• Access on top: an 18 inch threaded vented manway, 135 inches up. Fixed access with a rail, a fill that goes down inside rather than falling onto the surface, and a vent kept clear at all times; a blocked vent with a pump drawing is how a polyethylene wall gets pulled in.
• What the sheet publishes: a specific gravity rating of 1.9, a 120 F / 48 C limit and a 3 Year Warranty. No inlet size and no fitting schedule, so none is asserted.

The discipline that keeps a cone bottom tank useful is emptying it properly. Close the batch out through the valve, flush the cone, and let it drain rather than leaving a heel in the bottom to go hard between runs, because the one place solids are difficult to reach on this shape is the tip of the funnel where the valve lives. Keep a spare gasket for the discharge on the shelf rather than on a purchase order. And run a level device you can read from the floor, because at eleven feet three inches of shell nobody should be climbing to answer a question a gauge answers.

Batching, settling and a genuine drain-down

Cone bottom tanks are bought for duties where the tank has to empty completely and predictably: batching and blending in a chemical or agricultural mixing plant, holding a suspension that settles between runs, wastewater and sludge handling, clarifier and thickener feed, food and beverage process holding, a fertilizer or crop protection blend that has to leave the tank the way it went in, and any duty where the vessel is washed out between products. Three thousand six hundred gallons is a working batch rather than a bulk store, which is the size this shape usually gets specified at. Run the numbers before you commit to the cone angle and the height together in the tank sizing calculator; a tank that empties well but does not fit the building is not a solution.

An oversize load out of Arkansas, with a three year warranty behind it

The SII-8050000N42 is molded at Marked Tree, Arkansas and the sheet gives the freight class as OVS under NMFC 156600, which is an oversize move rather than an ordinary one. At 102 inches across and 135 inches tall it is a permitted load with a route rather than a rate off a table, so walk the approach before the truck is booked: the gate, the turn, the overhead lines, the place the trailer can stop, and the machine that will be there to take it off. The freight cost estimator prices the lane to your ZIP, and the listed price is before freight. Unload with slings under the body and a machine that can stand it up, never a hook through the manway, and stand it straight onto its finished, anchored stand rather than parking it on the yard to be moved again. Then water-test it before the product goes in: fill, hold, and read the cone fitting, the manway seal and every foot of the stand while there is only water to lose. This sheet publishes a 3 Year Warranty, so keep the part number, the delivery paperwork and the date of that first fill together in one file where somebody can find them. Photograph the outlet fitting from below before the pipe goes on; a slow weep is easier to compare against than to describe.
