Snyder Industries 3600 Gallon Black XLPE Cone Bottom Tank

Where a wide cone lands when the ceiling is the constraint

Ten feet and a few inches of shell is the reason to look at this listing before the taller ones. At 125 inches it is the short way to hold 3,600 gallons, and in a building with a fixed roof, a duct run, a crane rail or a mezzanine over the spot, short is the only specification that matters. What holds it up is a separate purchase entirely, and it is the part that catches people out. A cone bottom vessel has no flat bottom, so it cannot sit on a floor, and this sheet publishes no stand, no legs, no skirt, no support ring and no bolt pattern. The support is bought separately, set, levelled and anchored before the tank arrives, and no stand height, rated load or stand material appears on this page because none appears on the record. Settle it with the cone bottom tank stand compatibility matrix before a part number is fixed, and ask us to confirm the fit rather than assuming one from a picture. Then add the measurements in the order the building forces on you. Stand height, plus 125 inches of shell, plus clearance above the manway for a person and a fill line, and separately the room the cone needs to discharge into below. If that total does not clear the lowest fixed obstruction over the spot, the honest fix is a different shell rather than a shorter stand, because the clearance underneath is what a cone is for and it is the first thing a low building takes away. On the ground, the pad carries 1,090 pounds of empty tank, 30,024 pounds of water and 45,036 pounds at the rating, all arriving through stand feet inside a 102 inch circle rather than spread across a slab. That is designed ground with a designed bearing area at each foot. The wide circle is a help rather than a nuisance, since feet set further apart carry less each, and it is the quiet advantage of a squat shell. Give yourself an aisle all the way round while you are still drawing it, because the day somebody changes a gasket under the cone is the day that aisle repays the floor area it cost. Size the volume honestly before any of this is committed with the tank sizing calculator, and take the freeboard discipline from the tank sizing guide, since a product that warms or gasses needs headspace a tape measure will not give you.

One hundred and two inches across, four times over

Cover the part numbers and the top four rows are indistinguishable: identical gallons, identical 102 inch circle, identical 125 inch height, identical 1,090 pounds. What separates them is what each sheet publishes about the wall, and on this page that is a specific gravity rating of 1.5 with 45,036 pounds of max contents. The heavy duty listing on the same shell, 8050000N48, carries its own higher rating on its own page, and the only difference the two records publish is that rating and the contents figure that follows from it. Neither sheet describes a wall thickness, a layer count or any construction difference, so neither page invents one. Read the decision that way and it becomes simple. Water, treated water, and the large family of process liquids no heavier than water are what this rating covers, and that is most of what a cone bottom tank actually holds. Paying for a heavier rating you will never load is money spent on paperwork rather than on the installation. The two lower rows are the shape question rather than the rating question. 5150000N40 holds 3,000 gallons on a 90 inch circle at 144 inches, so it gives back a foot of floor in each direction and takes a foot and a half of ceiling for it. 5440000N40 holds 3,900 gallons on that same narrow circle at 180 inches and 1,100 pounds, fifteen feet of column, which is a different building entirely. This tank is the one that buys volume out of floor rather than out of height, and when the roof is the constraint that is the only trade available. Where the material question is the real one, the article on when crosslinking matters for a chemistry duty settles it better than a product page can.

An eighteen inch vented manway and an outlet field left empty

• The manway: 18 inches, threaded and vented, sitting at 125 inches plus the height of the stand. That is above head height in every installation, so a platform or fixed ladder with a fall protection plan belongs in the same drawing as the structure. Bring the fill to a coupling at working level rather than asking anyone to carry a hose up there.
• The vent: it arrives with the manway on this sheet rather than as a separately specified item. On a tank being drawn down by pump the air path is the wall's protection, so keep it clear, inspect it whenever the tank is opened, and never blank, tape or paint it.
• The outlet: this record has no outlet field at all, so no discharge size, thread, bulkhead or valve is published and none is claimed. 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.
• Below the cone: valve, any reducer and the first run of pipe go on their own steelwork off the stand, never on the tank, with a flexible connector at the first joint so pump vibration stays out of the wall. Ten feet of full column puts real static head on that joint.
• The cone angle: no angle field appears on this sheet and the product name carries none, so none is stated here. Ask and we will confirm the geometry against the part number rather than inferring it from a photograph.
• Ratings and blanks: a specific gravity rating of 1.5, 30,024 pounds of water at 3,600 gallons, 45,036 pounds of max contents, a service limit of 100 F / 37 C and a 3 Year Warranty on the warranty field. No inlet, no structural lug detail and no NMFC number is published.

Two questions are cheaper to settle now than later. What happens under the tank after a release is a containment question rather than a tank question, and the Captor containment comparison is the honest place to start it. How the vessel is marked matters because an inspector reads the outside of a bulk tank and never the purchase order, and the tank label and signage guide reconciles the different marking schemes on one vessel.

Process liquids no heavier than water, emptied between runs

This is the ordinary workhorse of the pair: a 1.5 rated cone in a shell short enough to go indoors under most roofs. Process and treated water holding that still has to drain fully. Polymer and coagulant make-up at a water or wastewater works. Liquid fertiliser and crop input blending at an agricultural retailer. Batch preparation and intermediate holding in manufacturing. Food and beverage duty where the vessel is rinsed between products. Wash and rinse water systems emptied between runs, and buffer volume between two stages running at different rates. In all of them the cone earns its keep at the changeover rather than during the run, and that is the part a flat bottomed tank cannot match: the vessel keeps draining toward one low point instead of leaving a ring of product on a floor to be shovelled, pumped or explained. The squat shape helps a second way, because a wide shallow vessel holds a blend together better than a tall narrow column does, so a product that wants to settle gives less trouble in this shell than in the 90 inch tanks listed beside it. At 3,600 gallons the residue argument stops being theoretical: whatever is left behind at a product change is a volume somebody has to account for. Check whatever you are holding in our chemical compatibility reference before the fittings are specified rather than after the first fill. On a vessel this size the level instrument is also worth choosing rather than inheriting, and the level gauge selection guide works through the technologies on their failure modes.

• Polyaluminum Chloride
• Potassium Carbonate
• Potassium Hydroxide
• Propylene Glycol (PP or 316SS fittings), or

Three year warranty, Arkansas origin, a shipment the height of the tank

Marked Tree, Arkansas is where this tank is moulded, and Arkansas is the origin state on the sheet, so the mid-South is the short lane and either coast is a long one. The freight class reads 300, a numeric class rather than a mode, the ship mode reads LTL, and the sheet publishes no NMFC number. The shipping size is listed at 102 inches by 102 inches by 125 inches at 1,090 pounds, which is the tank's own listed size: a large package at a moderate weight, and that is the shape freight pricing likes least. Price your own ZIP with the freight cost estimator; the listed price is before freight. It travels lying down and is stood up at your end, so nominate the machine and the person for that operation rather than improvising on the day. This sheet publishes no crane, no rigging, no permit and no escort detail, and none is stated here; settle the offload equipment and the delivery window with us before the truck is booked. Set, level and anchor the stand first. Sling under the body, never by the manway or the top of the cone, and keep the tank restrained from the moment it is upright, because an empty shell eight and a half feet across moves in wind long before anyone expects it to. Then fill it with clean water, hold the 30,024 pound load, and read the manway seal, the cone joint, the stand feet and the ground around the pad in daylight. Leave it standing full overnight and look again in the morning; what has moved overnight is almost never the tank. Photograph the tank standing full on day one and file it with the paperwork, because it settles every later argument about whether something has shifted. Photograph the outlet fitting from below before the pipe goes on; a slow weep is easier to compare against than to describe.
