Snyder Industries 4,400 Gallon XLPE 30 degree Cone Bottom Tank in White 1.5 s.g.

Why the 222 inch shell and not the 200 inch listings

Four tanks on this sheet hold 4,400 gallons on a 90 inch circle, and the number that separates this one from the other three is height. This tank is listed at 222 inches tall and 1,100 pounds empty. 5200000N42 and 5200000N48 are both listed at 200 inches and 1,700 pounds, and 5200000N46 is listed at 200 inches and 1,400 pounds. The sheet gives those figures and explains none of them, so we print them and let you take the one that fits. What that comparison means on a real site is simple enough to settle with a tape measure. This is the tallest listing in the group and the lightest, so it is the one to take where the building has the height, where the vessel stands outdoors in a frame, or where the process wants the extra head above a pump; the 200 inch listings are the ones to ask about where the roof, the crane hook or the door decides the argument, and they are heavier shells in the same circle. Neither is better in the abstract. Under all four sits the same problem, which is that a cone bottom tank has no flat floor to sit on and this sheet publishes no stand, no legs, no skirt and no support ring. The stand is a separate item, bought and set before the tank arrives, and we will not print a part number the sheet does not carry. Design around the loads rather than around the drawing: 1,100 pounds of empty tank, 36,696 pounds of water and 55,044 pounds at the rating all arrive through that structure into a circle 90 inches across, which is a foundation an engineer signs rather than a slab poured to match a photograph. Above the foundation, 222 inches of slender column wants restraint, wind exposure considered honestly, and a way for a person to reach the top opening that was designed at the same time as the stand rather than added afterwards. Settle the volume before any of that is drawn: run your batch size, your turnover and your refill interval through the tank sizing calculator, and take the freeboard a warming or gassing product needs from the tank sizing guide. On a tank this slender, the last two feet of height are the expensive ones to discover you needed.

Four 4400s, a 4100 and a wider 4600

Ignore the gallons column for a moment and read the last row, because it is the only row that changes the shape of the problem. 8050100C75501 holds 4,600 gallons, more than any of the 4,400s, on a 102 inch circle only 154 inches tall, at 1,200 pounds. That is a wider, much shorter vessel holding more product, and on a site with a roof over it, or a crane with a fixed hook height, or a delivery route with a low bridge on it, that difference decides the purchase on its own. What the wider tank costs is ground: a 102 inch circle plus the structure around it needs a bigger bund, a bigger pad and a wider aisle than a 90 inch one. The 5180000N40 row is the quiet option worth a look. It holds 4,100 gallons on the same 90 inch circle at 197 inches and 1,000 pounds, and where your batch is genuinely 4,000 gallons rather than 4,400, it is the shorter and lighter way to buy the same job. Between the four 4,400s the choice is height against listed weight and nothing else the sheet explains, and the sensible rule is to match whatever a drawing, a spares list or an existing installation already names. If the angle itself is still open, settle that before the part number: a 30 degree cone is the middle of the three common angles, and the cone bottom buyer's guide on angle selection sets 15, 30 and 45 degrees against each other on drainage, height and what happens with a product that packs.

A threaded vented manway, and the discharge the sheet leaves blank

• The vent comes with the manway: the sheet lists an 18 inch threaded vented manway, which means the breathing path arrives with the top fitting rather than being specified separately. That matters most on a cone, because a pump drawing off the lowest point of a 222 inch column pulls hard, and a wall that cannot take air in is a wall that takes the load instead. Keep the vent clear, inspect it on a schedule, and never tape, paint, wrap or blank it to control an odour.
• Access: 18 inches of opening at 222 inches, which is eighteen and a half feet before the stand is counted. Every routine that involves that manway needs a platform, a fixed ladder and a fall protection arrangement designed alongside the structure, and the fill line should come to a coupling at working level instead of asking anyone to carry a hose up there.
• The discharge: this sheet publishes no outlet size, no inlet and no bulkhead. The cone ends in a discharge and the sheet does not dimension it, so no number appears here. Tell us the line size, the valve type and the product, and we will confirm what this part number carries before anything is ordered.
• What hangs below the cone: the valve, any reducer and the first run of pipe are carried on their own steelwork off the stand, never on the tank. At 55,044 pounds of rated contents the static load at the end of a full column is what punishes a hanging valve, and a flexible connector at the first joint keeps pump vibration out of the wall.
• The stand: not on this sheet. No legs, no skirt, no ring and no bolt pattern is published, and none is invented here. It is a separate item, and it is also the thing that adds the most unplanned height to a site survey, so settle it before the tank is ordered.
• Ratings: a specific gravity rating of 1.5, 36,696 pounds of water at 4,400 gallons, 55,044 pounds of max contents and a service limit of 120 F / 48 C. No warranty term appears on this sheet.

Name the product when you order. Gasket, valve and fitting selection on a cone discharge all follow the chemistry, and on a vessel holding this much the expensive part of getting it generic is never the fitting itself. Where the tank stands over ground, a floor or a drain that would have to be recovered after a release, the containment question is separate from the tank question and deserves its own answer: the Captor containment comparison sets the contained polyethylene route against the alternatives on the points that actually decide it.

Bulk blending where the whole batch has to leave the bottom

A cone at this volume is a process vessel rather than a storage drum, and the duties are the ones where the bottom of the tank is where the work happens. Liquid fertiliser and crop input blending at an agricultural retailer, batch make-up and blending in chemical manufacturing, thickened sludge and settled solids at a treatment works, mineral and wash plant slurry handling, fermentation and settling in food and beverage production, and any operation that changes product in the same vessel and cannot afford to leave a heel behind. A flat-bottomed tank of this size leaves a layer at every changeover, and at 4,400 gallons that layer is not a nuisance; it is a disposal ticket and a contamination risk in the next batch. The narrow 90 inch shell adds one more consideration worth knowing before the order: a tall column stratifies more readily than a shallow one, so if your product separates, where you draw from and how you mix matter more here than the vessel does.

Oversize out of Lincoln at 1,100 pounds

This tank is moulded at Lincoln, Nebraska, and the sheet lists Nebraska as the state it ships from, which is a central lane into the plains and the Midwest and a long one to either coast. The freight class reads OVS, an oversize mode rather than a numeric class, under NMFC 156600, and it shipments at 90 inches by 90 inches by 222 inches, which means it travels lying down and is stood up at the site. Price the lane to your ZIP with the freight cost estimator; the listed price is before freight. An oversize move is booked rather than ordered: the route, the permits, the delivery window and the unloading equipment are agreed before the tank leaves the plant, and a site that has not planned how an eighteen foot vessel comes off a trailer is a site that pays for a second visit. Have the machine on site and the stand already set, levelled and anchored when the truck arrives. Eleven hundred pounds is light for the size, and that is the trap rather than the bonus: a tank this large and this light is moved easily by a gust of wind, so keep it restrained from the moment it is upright. Stand it, secure it, then fill it with clean water and hold that 36,696 pound load while somebody reads the manway seal, the cone joint, the stand feet and the foundation in that order. Walk the base again the next morning with the water still in it. On a slender column the thing that moves overnight is almost never the tank. Check the strap tension a week after the first fill; a tank settles a little, and the strap that was tight is loose.
