Snyder Industries 5500 Gallon Black XLPE Heavy Duty Cone Bottom Tank

Heavy product, tall column, and the discharge at the bottom of both

The duty that brings people to this part number is dense liquid in volume that still has to drain clean. Concentrated crop inputs, treatment chemistry that weighs half again what water weighs, brines, and blends that a lighter tank would hold only by running it part full. The number that settles it is 87,153 pounds of max contents against 45,870 pounds of water in the same 5,500 gallons, which is the whole reason the 1.9 rating exists: it lets you fill this vessel with your product rather than with headroom. Work out what your liquid weighs per gallon before you compare part numbers, because that one figure moves the decision more than price does. Then think about the column. Two hundred and forty-one inches of tank over a 90 inch circle is a tall, narrow shape, and dense product in a tall column is a concentrated load: 2,000 pounds of empty tank plus up to 87,153 pounds of contents arriving at a handful of stand feet rather than spreading over a slab. That concentration is why a cone foundation is engineered ground with a designed bearing area under every foot, and it is why the structure question gets settled before the tank question. This sheet publishes no stand, no legs, no skirt, no support ring and no bolt pattern, and a cone bottom tank cannot stand on its own bottom, so the stand is a separate item with its own lead time and we print no height, load or material for one. 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. Run the volume and the turnover through the tank sizing calculator, set the freeboard from the tank sizing guide, and work the support out against the cone bottom tank stand compatibility matrix before you commit.

Same shell, two ratings, two colours: reading the 5500 group

Four part numbers, one shell: 5,500 gallons, a 90 inch circle, 241 inches tall, every time. The sheet splits them two ways and no further. The first split is weight, 2,000 pounds on this listing and on 7040000N42, 1,500 pounds on the other two, and the sheet gives that difference as a figure with no explanation attached, so we repeat the figure and add nothing to it. The second split is colour, black on this listing and on 7040000N46, natural white on 7040000N40. Neither split is cosmetic in use. The weight difference travels with the rating, and this page's rating is 1.9 with 87,153 pounds of max contents, so if your product is heavier than water this is the column to read. The colour difference decides what daylight does to your contents: black keeps light out of the liquid, natural white lets an operator see a level through the wall from the walkway. You are choosing both at once here, and this part number is the one that says dense product, kept dark. The last two rows are different shapes rather than different grades: 8050200C75501 puts 5,000 gallons on a 102 inch circle at 166 inches, and 5280200N40 puts 6,000 gallons at just 136 inches by going out to a 142 inch circle. If your ceiling is the constraint, read those two before you read any rating. Where the crosslinked wall itself is the question, our read on XLPE against HDPE for chemistry duty covers it, and the capacity has its own long-form treatment in the 5,500 gallon cone bottom tank buyer's guide.

Working out from the cone outlet on a tank rated 1.9

• The outlet field: it reads 1 Manway / Lid on this sheet. That names an opening, not a discharge, and it is printed here exactly as it reads. No outlet dimension, no thread, no bulkhead and no valve is published, so none is stated. Give us the line size, the valve type and the product, and we will confirm what 7040000N48 carries before it is ordered.
• The drain path and the load above it: everything you hang at the low point of a cone is carrying the weight of the column when the tank is full, and on this listing that column is allowed to reach 87,153 pounds. Support the valve, any reducer and the first length of pipe on their own steelwork off the stand rather than off the tank, and put a flexible connector at the first joint so pump vibration never reaches the shell.
• Pumping dense product: a 1.9 rated liquid does not behave like water at the suction. Size the pump on the actual specific gravity rather than on the gallon figure, keep the run off the cone short, and expect the last of a dense batch to move more slowly than the first through the same line.
• The cone angle: no cone angle field is published on this sheet and the name carries none, so no angle is stated. Ask before ordering if the angle is load-bearing for your product.
• Access on top: an 18 inch threaded vented manway at the top of 241 inches of shell plus the stand. The vent comes with the manway here rather than being specified separately. On a vessel being pumped down that vent is structural, not optional, because a tank that cannot take air in takes the load in the wall instead.
• Inlet, lid size, lug and flange counts, warranty and NMFC: this sheet publishes none of them and none is claimed. The published ratings are a specific gravity of 1.9, 45,870 pounds of water at 5,500 gallons, 87,153 pounds of max contents and a service limit of 100 F / 37 C.

Where the vessel 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: the Captor containment comparison sets the contained polyethylene route against the alternatives, and on a dense 5,500 gallon load that comparison is worth reading before the pad is poured rather than after.

Where the density rating is the reason for the purchase

People do not pay the difference for a 1.9 rated shell because it sounds better. They pay it because their product weighs more than water and they want to fill the tank. Concentrated liquid fertiliser and crop protection blends, treatment chemistry at working strength, brines and process concentrates, and anything a supplier quotes to you by weight rather than by volume: those are the loads that put 87,153 pounds of allowance to work in a vessel that only holds 45,870 pounds of water. The black wall narrows it further. It is the choice for outdoor standing, for product that reacts to light, and for anywhere growth in a translucent tank has been a housekeeping problem before. The cone is the third reason and often the quiet one: a dense product left in the last inches of a flat floor is heavier, more valuable and more of a disposal problem than a light one, so full-drain geometry pays back faster at high specific gravity than it does at low. What this page will not do is name a chemical the sheet does not name. Bring us the liquid, its specific gravity and its temperature at fill, and we will check it against the wall, the gasket and the fitting selection in that order, because the chemistry drives the trim rather than the tank. The one figure to hold on to in that conversation is the service limit: this sheet publishes 100 F / 37 C. Start that check yourself in our chemical compatibility database, which is where the wall, the gasket and the fitting selection get decided.

Two thousand pounds empty, and a twenty foot shell lying on its side

Moulded at Lincoln, Nebraska, and the sheet gives Nebraska as the shipping state, so the Midwest is the short lane and the coasts are the long ones. The freight class reads 300 beside an LTL ship mode, and no NMFC number is published. Two thousand pounds of empty tank in a 90 by 90 by 241 inch envelope is still a light load for the space it takes, which is why a tank like this prices on dimensions rather than on weight. Get the lane figure for your own ZIP from the freight cost estimator; the listed price is before freight. This sheet publishes no crane, no rigging, no permit and no escort detail, so none is described here, and the offload equipment and the delivery window should be agreed with us before the truck is booked rather than on the morning. It arrives lying down. It is stood up at your end, and that is the part of the day people underestimate on a shell twenty feet long. No lifting lugs are listed on this sheet, so plan the lift under the body and never off the manway, and restrain the tank as soon as it is vertical because an empty shell that tall is a sail. Set, level and anchor the stand before delivery, not after. Commission it with clean water rather than with product, take it to the 45,870 pound water load, then walk the manway seal, the cone joint, the stand feet and the pad edge in that order before anything dense goes in. Mark the vent on the outside of the shell while you can still reach 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.
