Snyder Industries 6500 Gallon 30 Degree Plastic Cone Bottom Tank

Twenty-two feet of tank and the structure it stands in

A cone bottom tank does not stand on its own bottom, and at this height that fact governs everything. The cone is the whole point of the design, because the contents leave through the lowest point under their own weight instead of being pumped off a flat floor, but a cone has to be held up. This sheet publishes no stand, no legs, no skirt and no support ring, so nothing here tells you what it sits in. That is a question to settle before the tank is ordered, not after it is on the ground: the cone bottom tank stand compatibility matrix is where that gets worked through across makers, and we will confirm what fits this part number when you ask. What the sheet does give you is the envelope the structure has to live inside. Ninety inches across is a narrow circle for the volume, which is good news for floor space and bad news for stability: 273 inches of height on a 90 inch base is a slender column, and it belongs against a wall, inside a structure, or on a foundation and restraint arrangement designed by somebody who has seen the wind loading at your site. Indoors it needs the ceiling height, the crane access and the door opening to get it upright, and none of those are afterthoughts at twenty-three feet. The load is the other half. Empty it is 2,100 pounds, the sheet gives 54,210 pounds full of water and 81,315 pounds at the rating, and that whole load arrives through the stand into a footprint the size of a small table. The pad or the foundation under it is an engineered element, not a slab you pour to match the drawing. Confirm the volume against your real batch and turnover in the tank sizing calculator before the structure is designed around it, and take the freeboard a warming or gassing product needs from the tank sizing guide, because on a tank this slender the last two feet of height are the expensive ones to add later.

Three sixty-five hundreds at ninety inches, and two wider tanks beside them

Four of these six are the same 90 inch by 273 inch shell holding the same 6,500 gallons, listed at 2,100, 2,100, 2,800 and 2,100 pounds. The sheet gives those weights and explains nothing about them, so we print what it says: this tank is one of the lighter listings in that group and it is the one rated at a specific gravity of 1.5. Where a heavier product is going in, 7180000N42 is the 2,800 pound listing in the same envelope and it is the one to ask us about, because the extra seven hundred pounds of wall is the only difference the sheet shows. The last two rows are a different proposition entirely and they are the rows most buyers should read first. 5280200N40 holds 6,000 gallons, almost as much as this tank, in a 142 inch plan only 136 inches tall, at 1,100 pounds. SII-5320100N43 holds 7,400 gallons on the same 142 inch plan at 160 inches tall and 1,600 pounds. Both are roughly half the height of this tank and both weigh less. The trade is floor: 142 inches across is more than fifty inches wider than this shell in every direction, which is a different building. Buy this 90 inch cone when the floor is the constraint and the roof is not, when the tank can be tied into a structure, and when a tall narrow column fits the process better than a squat one. Buy wide when the ceiling, the crane or the wind exposure is what limits you.

The cone discharge, and what the sheet does not give

• The discharge: this sheet publishes no outlet size and no bulkhead. The cone ends in a discharge and the sheet does not dimension it, so we print no number. Tell us the line size, the valve type and what you are moving, and we will confirm what this part number carries before anything is ordered.
• The valve underneath: whatever goes on a cone discharge is carried on its own support, never on the tank. At this volume the valve, the reducer and the first length of line want their own steelwork off the stand, so that nothing hanging below the cone is loading a polyethylene wall.
• Draining and dead volume: a 30 degree cone is a shallow cone, and shallow cones move free-flowing liquid well and hold onto anything that packs. If your product settles hard or drains slowly, that is the argument for a steeper angle, and the cone bottom buyer's guide on cone angle selection compares the angles on the terms that decide it.
• Access: an 18 inch threaded vented manway on top, which at 273 inches means a platform, a ladder and a fall arrest arrangement rather than a step. Plan how a person reaches that manway at the same time as you plan the stand, because it is the only published opening on the tank.
• The vent: the manway is listed as vented, and on a vessel this tall the vent path is what protects the wall while a pump is drawing off the bottom. Keep it clear, inspect it on a schedule, and never blank it to stop a smell.
• Limits: 120 F / 48 C, a specific gravity rating of 1.5, and a 3 Year Warranty. That is the extent of what this sheet publishes.

Name the product when you order. Fitting material, gasket and valve selection on a cone discharge all follow the chemistry, and on a tank holding this much the cost of getting it generic is not the fitting. Where the vessel is standing over a floor, a yard or a drain that would have to be recovered, the Captor containment comparison argues the containment question properly rather than assuming it away.

Bulk batching where the solids have to leave the bottom

Six and a half thousand gallons over a cone is a process vessel, not a storage drum. The duties are the ones where the bottom of the tank is where the work happens: mixing and batching in a chemical plant, thickening and sludge holding at a treatment works, fermentation and settling in food and beverage production, mineral and slurry handling at a wash plant, liquid fertiliser and crop input blending at an ag retailer, and any process where the vessel has to be emptied completely between products. A flat-bottomed tank of this volume leaves a layer behind at every changeover, and at 6,500 gallons that layer is not a nuisance, it is a cost with a disposal ticket attached. The narrow 90 inch shell adds one more thing worth knowing: a tall column of liquid stratifies more readily than a shallow one, so if your product separates, the draw-off point and the mixing arrangement matter more here than the tank does.

Resin compatibility, line by line

Below are the liquids this resin is rated for, the concentration each rating holds to, and the fitting and gasket to specify. Check the exact concentration and temperature you run against the chemical page or the chemical compatibility database before ordering.

• Acetic Acid (60%) - PP/PVC fittings, EPDM gaskets
• Aluminum Sulfate (50%) - PVC fittings, EPDM gaskets
• Calcium Chloride (40%) - PVC fittings, EPDM gaskets
• DEF (32.5%) - 316SS fittings (not PVC), EPDM gaskets
• Ferrous Sulfate (20%) - PVC fittings, EPDM gaskets
• Magnesium Chloride (30%) - PVC fittings, EPDM gaskets
• Sodium Carbonate (30%) - PVC fittings, EPDM gaskets
• Urea Solution (50%) - PP/PVC fittings, EPDM gaskets

Oversize out of Lincoln at 2,100 pounds

This tank is moulded at Lincoln, Nebraska, and the sheet lists Nebraska as the state it ships from. Price the lane to your ZIP with the freight cost estimator; the listed price is before freight. An oversize move is booked, not ordered: the route, the escort requirement, the delivery window and the unloading equipment all get agreed before the tank leaves the plant, and a site that has not thought about how a twenty-three foot vessel comes off a trailer is a site that will pay for a second visit. Have the crane or the extendable-reach machine on site and the stand ready before the truck arrives. Set it, restrain it, and only then fill it with clean water and hold that 54,210 pound load long enough to read the manway seal, the discharge joint and, more importantly, the foundation and the stand. The one instruction that matters most on a tank this tall is to walk the base with the water still in it and look at the level again the next morning. Walk the base after the first hard rain; a pad that shifts shows it at the edge first.
