Snyder Industries 3900 Gallon XLPE Cone Bottom Tank

Ceiling, stand and the pad that takes it all at once

Three measurements decide whether this tank goes where you want it, and the order matters. The first is headroom. The shell is 180 inches before anything is underneath it, fifteen feet, and the manway needs working clearance above that again. The second is the stand, which is not on this sheet at all: no stand, no legs, no skirt, no support ring and no bolt pattern is published, so the support is a separate purchase and no stand height, rated load or stand material is stated on this page. A cone bottom tank cannot stand on its own bottom, so this is not an accessory, it is half the installation, and it is specified, built and set before the tank arrives rather than after. Settle it with the cone bottom tank stand compatibility matrix and confirm the fit with us against this part number before the order goes in. The third measurement is the floor, and it catches out anyone who expects a cone to spread its weight. It does not. The pad takes 1,100 pounds of empty tank, a published full water weight of 32,526 pounds and 48,789 pounds at the rating through the feet of a stand, concentrated inside a 90 inch circle instead of spread across a slab, which is exactly why a cone foundation is designed ground with a bearing area at each foot rather than a slab poured to suit the drawing. Two things get forgotten at this height. One is the clearance under the cone, which is what a cone is for and the first thing a short building takes away. The other is the aisle: at seven and a half feet across and fifteen feet tall, nobody reaches the far side or the top from one position, and the day a gasket is changed under the cone is the day the aisle pays for itself. Size the volume before any of this is drawn with the tank sizing calculator and take the freeboard from the tank sizing guide, because a product that warms or gasses needs headspace a tape measure will not give you.

Reading the 3900 family by weight and by rating

Cover the gallons column and the top four rows stop being four tanks. They are one 90 by 90 by 180 inch shell listed four ways, and the sheet separates them by empty weight and by the name printed on each: 1,100 pounds on this listing and on the black standard listing, 1,400 pounds on the two heavy duty ones. The sheet explains none of that and this page prints the figures instead of theorising about them. The decision you can actually make is the rating. This listing is rated at a specific gravity of 1.5 with 48,789 pounds of max contents, which covers water, treated water and the large family of process liquids no heavier than water, and that is most of what a cone bottom tank really holds. If your product is genuinely denser than that, take the rating that matches it and do not ask the wall to do the arguing. Colour is the other choice inside the quad and it is about where the tank stands rather than what it holds: natural white lets an operator read a level through the wall in daylight, and the black listings keep light off the contents. The last two rows change the shape of the problem. 5180000N40 holds 4,100 gallons at 197 inches on the same 90 inch circle, which is more volume for no extra floor if the building has the height. 8050000N40 holds 3,600 gallons on a 102 inch circle at 125 inches, which is the low-roof answer and costs floor area instead. Because the circle only changes on the last row, you can move up and down this ladder without redrawing the pad, the bund or the aisle, and that is worth exploiting when the building is the constraint.

Start at the drain: what this sheet sizes and what it leaves open

• The outlet field: it reads 1 Manway / Lid. That is the field value, it names an opening rather than a discharge, and we print it exactly as it reads. No outlet size, no thread, no bulkhead and no valve is published or claimed on this page. Give us the line size, the valve type and the product and we will confirm what this part number carries before it 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 length of pipe on steelwork off the stand, never on the tank, and put a flexible connector at the first joint. With 48,789 pounds of rated contents above it, a hanging valve on fifteen feet of column is a problem waiting for a quiet weekend.
• The cone angle: none is published on this sheet and none appears in the product name, so none is stated here. If the way your product drains is the deciding factor, ask us to confirm the geometry against the part number rather than inferring it from a picture.
• Access on top: an 18 inch threaded vented manway at 180 inches plus the stand. Platform, fixed ladder and a fall protection plan belong in the same drawing as the structure, and the fill line belongs at a coupling at working level.
• Filling: no inlet is published on this sheet, so the fill route is designed rather than assumed. Land the line into the manway and size the air path to the faster of your fill rate and your draw rate, not to whichever one you thought of first.
• Ratings and blanks: a specific gravity rating of 1.5, a published full water weight of 32,526 pounds at 3,900 gallons, 48,789 pounds of max contents and a limit of 100 F / 37 C. No structural lug detail, no warranty term and no NMFC number appears on this sheet.

A bulk vessel is read by people who did not order it, so settle the marking at the same time as the fittings: the tank label and signage guide reconciles the different marking schemes on one tank. On a column this deep the level instrument is the other thing cheaper to get right first than to retrofit, and the level gauge selection guide works through the technologies honestly. Where the tank stands over ground or a floor that would have to be recovered after a release, the Captor containment comparison is the place to start the containment question, because it sometimes changes the layout rather than adding to it.

Process and blend duty no denser than water

This is the ordinary workhorse of the quad, and the volume is what makes it interesting: 3,900 gallons is enough to take a full bulk drop without splitting it between vessels. Process and treated water holding that still has to drain fully, liquid fertiliser and crop input blending at an agricultural retailer, polymer and coagulant make-up at a water or wastewater works, batch preparation and intermediate holding in manufacturing, food and beverage duty where the vessel 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 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 pumped, shovelled or explained. Natural white adds one practical thing on this listing, which is that an operator can see roughly where the level sits through the wall in daylight without climbing anything, and on a fifteen foot tank not climbing is worth something. The honest limitation is stratification: a tall slender column separates more readily than a wide shallow one, so plan the draw point and the mixing arrangement together. Check your liquid in our chemical compatibility reference before the fittings are chosen, because the product decides the gasket and the valve, not the vessel.

Eleven hundred pounds on a fifteen foot shipment

Lincoln, Nebraska is where this one is moulded, and the sheet gives Nebraska as the origin state, so the central lanes are short and either coast is long. The freight class reads 300, a numeric class rather than a mode, and no NMFC number is published. The package is 90 inches by 90 inches by 180 inches at 1,100 pounds: a large, light load that takes trailer length rather than payload, which is exactly the shape that surprises people when the freight quote arrives. Run your own ZIP through the freight cost estimator before you commit to the shape; the listed price is before freight. It travels lying down and somebody stands it up at your end, so nominate the machine and the person for that job in advance rather than solving it on the tailgate. The sheet publishes no crane, no rigging, no permit and no escort detail, and this page states none; agree the offload arrangement and the 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 stands upright. Then prove the installation with clean water before product goes near it: hold the water load, walk the manway seal, the cone joint, the stand feet and the ground around the pad with a torch, and leave it standing full overnight. Check the anchor bolts and the strap tension again a week later, because ground settles a little under a new load and the fixing that was tight on day one is the one that is loose on day eight. Note the pad height and the outlet height on the site plan while the tape is out; the next pipe run will need both.
