Snyder Industries 2000 Gallon 30 Degree XLPE Cone Bottom Tank in White 1.9 sg

The stand, the pad and the height this cone needs under it

A cone bottom tank does not stand on its own bottom, and that single fact drives the whole installation. This vessel is held up by a structure that carries it around its shoulder or its skirt, with the cone and whatever hangs off it in clear air underneath. The sheet publishes no stand, no legs and no support ring, so nothing here describes what it sits in; that structure is a separate specification, settled before the tank is ordered rather than improvised after it arrives. What the sheet does give you is the envelope that structure has to serve. At 90 inches across and 102 inches tall, the tank alone stands eight and a half feet, and the stand adds its own height beneath that. Measure to the lowest obstruction in the building, not to the ceiling, and then add the stand, because the beam, the sprinkler main, the light fitting and the door header are what actually decide whether this tank goes where you want it. The other dimension that matters is the clear space below the cone. You need room for a valve, for a hose or a pipe run, and for a person to get under there with a spanner, and that room is bought at the top of the tank in ceiling height. Then there is the load. Empty the tank is 400 pounds, which is nothing; the sheet gives 16,680 pounds full of water and 31,692 pounds at the rating, and unlike a flat-bottomed vertical, none of that weight is spread across a floor. It arrives through a small number of stand feet as concentrated point loads, which is a different foundation problem and an engineered one. The concrete pad sizing guide for above-ground polyethylene tanks is the honest starting point and it also says where its own framework stops and a structural engineer starts. Confirm 2,000 gallons is your real working volume in the tank sizing calculator before the structure is designed around it, and take the freeboard for a warming, gassing or foaming product from the tank sizing guide. Where the vessel stands over a floor, a yard or a drain that would have to be recovered after a release, the Captor containment comparison argues the containment question properly rather than assuming it away.

Four two-thousands, a sixteen-fifty and a twenty-five hundred

Four of these six hold 2,000 gallons in the identical 90 by 90 by 102 inch shell, and the only published difference between them is the empty weight: two are listed at 325 pounds and two, including this one, at 400. The sheet says nothing about why, so neither will we, and guessing at what a part number implies about a wall is exactly how the wrong tank gets bought. Where a drawing, a spares list or an existing installation already names one of those numbers, order that number and ask us to confirm the figures against the part before it ships. The rows worth studying are the last two, because they show what the shape decision costs. 1910000N42 holds 1,650 gallons on an 86 inch plan 94 inches tall at 300 pounds: a slightly narrower plan and a lower shell for a few hundred gallons less, which is the tank to look at when a door, a bay or a low header is the binding constraint and the volume is negotiable. 5110000N40 keeps this tank's exact 90 inch plan, stretches to 125 inches tall and holds 2,500 gallons at 375 pounds. That is 500 more gallons on ground you have already committed and a stand you have already designed, bought entirely in height. That is the cleanest way to read this family. If the ceiling is generous, buy the height, because the footprint and the foundation are the expensive parts of a cone installation and they do not change. If the ceiling is the problem, step down the plan rather than trying to squeeze the taller shell in.

A discharge the sheet does not size, and the manway above it

• The discharge: the cone ends in a discharge and this sheet publishes no outlet size, no inlet and no bulkhead, so no number appears here. It is the first thing to settle when you enquire, because the line size sets the drain time, and the drain time is what decides whether a batch changeover takes minutes or most of an hour. Tell us the product, the line size, the valve type and the pump, and we will confirm what this part number carries before anything is ordered.
• The valve and the pipe under it: whatever hangs below the cone is carried on its own steelwork off the stand, never on the tank. With 31,692 pounds of max contents above it, the static head at the bottom of a full vessel is not where you want to discover that a valve was hanging on a moulded fitting.
• Angle and drain behaviour: the name gives 30 degrees and the sheet gives no cone angle field. Thirty degrees is the middle of the common range: it moves free-flowing liquid well and holds on to material that packs or bridges. If your product settles hard, that argues for a steeper cone rather than a bigger tank, and the cone bottom buyer's guide on angle selection sets the angles against each other on the terms that actually decide it.
• Access: an 18 inch threaded vented manway at the top of a 102 inch tank standing on a stand. That is a platform, a fixed ladder and a fall protection arrangement designed alongside the structure, not added the week after commissioning.
• The vent: the manway is listed as vented, and that vent path is what protects the wall while a pump draws the column down or a delivery pushes air out. Keep it clear, inspect it whenever the manway is opened, and never blank it to control an odour.
• Limits: 140 F / 60 C, a specific gravity rating of 1.9, and no warranty term on this sheet. The temperature limit is the highest in its batch and it is the reason this tank turns up on duties the others cannot take.

Name the product when you order. On a cone discharge the gasket, the valve body and the first joint all follow the chemistry, and on a vessel holding this much the cost of getting that generic is never the price of the fitting.

Blending, settling and load-out that has to leave nothing behind

Two thousand gallons over a cone is bought by operations that empty the vessel on purpose and then put something else in it: liquid fertiliser and crop input blending at an ag retailer, mixing and batching on a chemical process line, polymer and thickened sludge duty at a treatment works, mineral and slurry handling at a wash plant, fermentation and settling in food and beverage production, and drilling or completion fluid holding where a load-out has to leave the tank clean. A flat floor at this volume leaves a layer behind at every changeover, and that layer is not a housekeeping complaint, it is a disposal ticket and a contamination risk in the next batch. The cone removes it. The 140 F / 60 C service limit on this particular sheet widens the field further, because a warm wash, a heated make-up or a product that arrives hot is exactly where a lower-rated vessel gets ruled out. If your duty runs warm, say so when you enquire and say how warm, because the limit is the tank's and the excursions are yours.

Oversize out of Lincoln at four hundred pounds

This tank is moulded at Lincoln, Nebraska, and the sheet lists Nebraska as the state it ships from, which puts the plains and the Midwest on a short lane and everywhere else on a planned one. The freight class reads OVS, an oversize mode rather than a numeric class, under NMFC 156600, and the tank measures 90 by 90 by 102 inches. Price the lane to your ZIP with the freight cost estimator; the listed price is before freight. An oversize move is booked rather than simply ordered: the route, the delivery window and the unloading equipment are agreed before the tank leaves the plant. At 400 pounds the weight is not the problem, the shape is, so have a machine with the reach to take a seven and a half foot body off a trailer and set it on a stand that is already built, levelled and anchored. Lift it by the body and never by the manway. Once it is set and restrained, fill it with clean water and hold that 16,680 pound load long enough to read the manway seal, the discharge joint, the stand feet and the foundation, in that order and in that priority. Walk the stand again the next morning with the water still in it, because a structure that is going to settle does it in the first day. Only after that water comes out and the vessel is dry does the working product go in. Write the fill date on the manway with a paint marker; it answers the first question anyone asks about a tank.
