Snyder Industries 1650 Gallon Heavy Duty Cone Bottom Tank

The bulk duty that pays for a cone at this size

Start with the duty, because 1650 gallons is a commitment and the shape costs more to install than a flat bottom tank of the same volume. A vessel this size is bought by operations that make a batch, hold it for hours or days, and then move all of it: chemical distributors running a day tank into a loading rack, water and wastewater plants making up coagulant or polymer, agricultural blenders filling nurse tanks, food and beverage sites holding a batch between process steps, and manufacturers who change product often enough that a heel in the bottom is a contamination problem rather than an inconvenience. That last case is the one that pays for the cone. Spread 1650 gallons across an 86 inch flat floor and the residue you cannot reach is measured in tens of gallons; run the same volume down to a point and the vessel empties under its own weight, the solids go where the liquid goes, and a changeover is a rinse rather than an entry. Settling duty is the second argument. Anything that separates, drops out or thickens ends up at the discharge instead of across the whole base, which turns a cleaning job into a draining job. The price is height and support. At 94 inches tall before anything is put underneath it, this tank is already near the ceiling of a lot of buildings once it is on a structure, and the sheet publishes no stand, no legs, no frame, no cradle and no load or height for one. Settle the support before the tank is ordered, not after it lands: a cone bottom tank with nowhere to sit is an object you cannot put down. The general matching problem is worked through in the cone bottom tank stand compatibility article, and we will confirm what Snyder pairs with this part number when you ask. Measure to the lowest obstruction over the pad rather than to the ceiling, then check the volume is the right volume with the tank sizing calculator and take the headspace from the tank sizing guide before you commit to the footprint.

Four sixteen-fifties and the sizes either side

Four listings hold 1650 gallons in the same 86 inch circle at the same 94 inches and the same 300 pounds. This one is the black listing in high density linear polyethylene; the others are listed as cross-linked, and SII-1910000N45 is the white one. Where a site already runs one of them, buy the listing that matches the paperwork it already has, because on dimensions alone there is nothing to choose between them. The interesting comparison is sideways rather than up. 8330000N42 holds 1600 gallons, fifty less, in a 95 inch circle at 72 inches tall and 277 pounds: nearly the same volume, nine inches more diameter and almost two feet less height. If your constraint is a roof, a mezzanine or a door frame, that is the one to look at, and if your constraint is floor area, this one is. 5070000N40 goes the other way at 2000 gallons on a 90 inch circle, 102 inches tall and 325 pounds, which buys a third more volume for eight inches more height. Decide in this order: the height you can actually accommodate once the tank is on its support, then the footprint, then the gallons. Buying a cone on capacity first is how sites end up cutting a hole in a ceiling or discovering the fill point is out of reach.

Draining a thirty degree cone through the point

• The discharge path: the cone degrees field reads 30, and everything in the vessel arrives at the point under gravity. That is the drain path this shape gives you and it is the reason to buy it. What the sheet does not give is the fitting at the bottom: the outlet field reads 1 Manway / Lid and no bulkhead, valve, thread or size is published, so none is stated here.
• The opening above: 7 inches, as listed. That is the fill, sample and inspection point, and at 94 inches of tank it is a ladder or platform job, so plan access to it before the tank is standing.
• Inlet: none published on this sheet. Fill through the top opening unless we confirm otherwise with the maker for your part number.
• Service limit: 100 F / 37 C, as the sheet gives it. That ceiling is on the contents, and a black tank standing outdoors on a still day gets warmer than the liquid that went into it.
• The wall: cited at a specific gravity rating of 1.9, holding 13761 pounds of water at full and 26146 pounds of max contents. Weigh your own product against those figures and ask us where it sits near the line.
• Structural: four tie-down lugs and one flange line are what the sheet records. No anchor specification, no strap size and no wind or seismic detail is published, so none is claimed. Where the install needs restraint engineered, ask before ordering.

Name the liquid, its temperature and its concentration when you order. At 1650 gallons the sizing is the straightforward part and the fittings, the support and the access are where installs run late.

Where a sixteen-fifty sits in a process

A tank this size is rarely the only vessel on the site; it is the one in the middle, taking a delivery or a batch and feeding something smaller downstream. That position dictates the rest of the installation. Level indication becomes a requirement rather than a nicety, because nobody is opening a top hatch at this height to look, and a black wall tells you nothing from outside; the options and their failure modes are compared in the tank level gauge selection guide. Labelling becomes a requirement too, because a vessel holding this much of anything is the one an inspector walks to first, and getting hazard marking, pictograms and pipe marking to agree across several standards takes more thought than a printed sign; that reconciliation is worked through in the tank label and signage article. And containment becomes the question that decides the pad, because catching the contents of a vessel this size is a civil job rather than a tray; the arithmetic and the alternatives are set out in the Captor containment comparison. Check the product against our chemical compatibility reference before you commit the shell, and tell us the concentration and the service temperature, because those two move an answer more often than the chemical name does.

Three hundred pounds, class 400, two plants

This tank is listed against two plants, Chowchilla, California and Lincoln, Nebraska, with California and Nebraska as the shipping states, which puts the west coast and the middle of the country on short lanes. Freight is class 400 on an LTL ship mode, on a tank listed at 300 pounds empty and 300 pounds to ship. Three hundred pounds is light for the size, and that is exactly the trap: this is a bulky movement rather than a heavy one, so the cost and the risk are in the dimensions, not the scale ticket. An 86 inch circle standing 94 inches tall needs a machine to take it off the truck, a route to the pad that is wide enough, and somebody who knows where it is going before the driver arrives. Price the lane to your ZIP with the freight cost estimator; the listed price is before freight. Inspect the cone, the point and the top opening while the tank is still on the ground and reachable, because once it is up on its support the underside is the part you will never look at closely again. Write the fill date on the manway with a paint marker; it answers the first question anyone asks about a tank.
