Snyder Industries 3000 Gallon Cone Bottom Tank

The stand goes under 144 inches, and the pad goes under the stand

Start at the ground, because on a cone bottom tank the ground is the part that gets under-built. This vessel has no flat floor. It cannot stand on its own bottom, it never could, and this sheet publishes no stand, no legs, no skirt, no support ring and no bolt pattern. The stand is a separate item with its own lead time, specified and set before the tank arrives, and we will not print a height, a rated load or a material for one the sheet does not carry. What the sheet does give you is the envelope the structure lives inside and the loads it has to carry, which is exactly what an engineer asks for first. The shell is 144 inches tall, twelve feet, and every inch of stand goes underneath that, so your finished height is the stand plus 144 inches plus working clearance above the manway. In a plant room, measure to the lowest fixed thing over the spot rather than to the ridge: a sprinkler main, a crane rail, a duct run or a light fitting decides this, and it is almost never the thing people measure first. Then look down at the loads. They are 500 pounds of empty tank, 25,020 pounds of water and 37,530 pounds at the rating, and on a cone they arrive at a handful of stand feet rather than spreading across a slab the way a flat bottomed tank spreads them. That concentration inside a 90 inch circle is the whole reason a cone foundation is engineered ground with a designed bearing area at each foot. Leave clearance under the cone as well, because the discharge has to reach a pump, a tote or a drum, and the height you lose there is height you cannot buy back later. Settle the volume before any of it is drawn: run your batch size and refill interval through the tank sizing calculator, take the freeboard discipline from the tank sizing guide, and work the support out properly with the cone bottom tank stand compatibility matrix before a part number is fixed.

One ninety inch circle, four weights, and a wider 3600

Four of these rows are one shell. Same gallons, same 90 inch circle, same 144 inch height, and the sheet separates them by empty weight and by the name it prints on each: 500 pounds on this listing and on the two XLPE listings, 670 pounds on the heavy duty one. No account of that difference appears on the sheet and none is invented here. What you can act on is the rating, and on this listing the rating is 1.5 with 37,530 pounds of max contents. If your product is no denser than water, that is the number you need, and paying for a heavier rating you will never load is money spent on paperwork. The bottom two rows change the problem rather than the price. 5100000N40 is a step down to 2,600 gallons on the same circle at 139 inches, which is the honest buy when the real batch is smaller than the round number in the specification. 8050000N40 goes the other way and holds 3,600 gallons on a 102 inch circle at only 125 inches, so it buys more volume out of less height by taking more floor. That is the trade that decides most cone purchases: ceiling against ground. Two longer reads cover the rest of it properly, one on this capacity in a shallower cone and one on the 30 degree shell in natural white: the buyer's guide for a shallower cone at this capacity and the buyer's guide for the natural white 30 degree shell.

The outlet field reads as an opening, not a discharge

• The outlet field: it reads 1 Manway / Lid on this sheet. That names an opening and not a discharge, and we print it exactly as it reads rather than turning it into a pipe size. No outlet dimension, no thread, no bulkhead and no valve is published or claimed here. Tell us the line size you need to land, the valve type and the product, and we will confirm what this part number carries before anything is ordered.
• The drain path in practice: on a cone the discharge is the low point of the whole vessel and everything hangs off it. Carry the valve, any reducer and the first run of pipe on their own steelwork off the stand, never on the tank, and put a flexible connector at the first joint so pump vibration stays out of the wall. With 37,530 pounds of rated contents above it, the bottom of a full column is the wrong place for dead weight.
• The cone: published at 30 degrees, the middle of the common angles. That keeps a free-flowing liquid moving toward one point and will hold onto material that packs or consolidates. If your product settles hard, say so when you enquire and let us talk about geometry rather than capacity.
• Access on top: an 18 inch threaded vented manway at 144 inches plus the stand. The vent arrives with the manway on this sheet rather than being specified separately, which matters on a vessel being pumped out, because a wall that cannot take air in takes the load instead. Keep it clear and never blank, tape or wrap it to control an odour.
• What the sheet does dimension at the shell: 4 tiedown lugs, 8 lifting lugs, ladder lugs and 2 flange lines. The lifting lugs are the difference between a planned lift and an improvised one on the day.
• Inlet, warranty and NMFC: none of the three is published, and none is claimed. Ratings are a specific gravity of 1.5, 25,020 pounds of water at 3,000 gallons, 37,530 pounds of max contents and a limit of 100 F / 37 C.

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.

Blending and batch duty where the tank has to empty clean

A 1.5 rated cone at 3,000 gallons is bought by operations that need the vessel emptied properly rather than merely emptied. Liquid fertiliser and crop input blending at an agricultural retailer, polymer and coagulant make-up at a water or wastewater works, batch preparation in manufacturing, process and treated water holding that still has to drain fully, food and beverage duty where the tank is washed between products, and buffer volume between two stages that run at different rates. The cone earns its keep at the changeover rather than during the run, which is why people who have only used flat bottomed tanks underestimate it: the vessel keeps draining toward one low point instead of leaving a ring of product on a floor. At 3,000 gallons that residue is a disposal ticket and a contamination risk in the next batch, not a nuisance. One honest caution belongs to the shape rather than the tank: a twelve foot column on a 90 inch circle stratifies more readily than a wide shallow vessel, so if your product separates, the draw point and the mixing arrangement matter more here than the specification does. Name the liquid when you enquire and check it in our chemical compatibility reference first, because the gasket and fitting selection follows the chemistry and not the tank.

Five hundred pounds, class 400, out of Lincoln

This tank is moulded at Lincoln, Nebraska, and the sheet gives Nebraska as the state it ships from, which puts the plains and the Midwest on the short lane and both coasts on the long one. The freight class reads 400, a numeric class rather than a mode, and the sheet publishes no NMFC number. It shipments at 90 inches by 90 inches by 144 inches at 500 pounds, which is a light tank on a large ticket, and that combination is normal on hollow moulded goods that fill a trailer without weighing much. Price the lane to your ZIP with the freight cost estimator; the listed price is before freight. It travels lying down and is stood up at your end, and that standing operation is the part of the day that goes wrong when nobody has planned it. The sheet publishes no crane, no rigging, no permit and no escort detail, so none is stated here; agree the offload equipment and the window with us before the truck is booked. Have the stand set, levelled and anchored first, because a cone bottom tank with nowhere to stand is a tank lying in your yard taking up the space you needed. Lift under the body or by the lifting lugs the sheet lists, never by the manway, and keep it restrained the moment it is upright, because twelve feet of empty shell takes wind at a speed that surprises people. Then prove the installation with clean water rather than product: hold the 25,020 pound load, read the manway seal, the cone joint, the stand feet and the pad edge in that order, and leave it standing full overnight. Mark the vent on the outside of the shell before anyone climbs it, because the fitting that gets capped by mistake is always the one nobody labelled. Leave room to walk all the way around it; the side of the tank nobody can see is the side that leaks.
