Snyder Industries 3000 Gallon XLPE Heavy Duty Cone Bottom Tank

Nebraska origin and a twelve foot shell on its side

Take the logistics first, because on a tank this shape they are half the project. It is moulded at Lincoln, Nebraska, with Nebraska given as the origin state on the sheet, so the plains and the Midwest are the short lane and the coasts are the long ones. What travels is 90 inches by 90 inches by 144 inches at 670 pounds, twelve feet of shell lying on its side, and the freight class reads 400, a numeric class rather than a mode, with no NMFC number published. That is a large, light load priced on the deck it occupies rather than on its weight, so run the lane through the freight cost estimator before the specification is locked; the listed price is before freight. The receiving end then has two jobs. One is standing it up, and the sheet helps by listing 8 lifting lugs and 4 tiedown lugs on the shell, so the lift can be planned around published points rather than around a sling position somebody guesses at the kerb. The other is what it stands on, which this sheet does not publish at all: no stand, no legs, no skirt, no support ring and no bolt pattern appears, and a cone bottom tank has no flat bottom, so the support is a separate item and no stand height, rated load or stand material is stated on this page. Settle it with the stand compatibility matrix and ask us to confirm the fit against this part number. The finished height is the stand plus 144 inches plus clearance above the manway, measured down from the lowest fixed thing over the spot, and the pad below carries 670 pounds of empty tank, 25,020 pounds of water and 47,538 pounds at the rating through stand feet inside a 90 inch circle. On a black shell standing outdoors, add restraint and wind exposure to the same calculation. Size the volume before the structure with the tank sizing calculator and take the freeboard from the tank sizing guide.

Four rows, one shell, two ratings

Four rows, one shell, and only two things separating them: the empty weight the sheet prints and the name it gives each listing. It is 670 pounds on the two heavy duty listings and 500 pounds on the two standard ones, with no account of the difference on the sheet and none invented on this page. The decision that matters is the rating, and this listing carries the higher one: a specific gravity rating of 1.9 with 47,538 pounds of max contents, which is the figure for a product noticeably heavier than water. If yours is not heavier than water, the 500 pound listings are the more honest buy rather than the less careful one. Colour is the second split and it decides where the tank lives rather than what it holds. This one is black, so daylight stays off the contents, which suits a vessel standing in the open for years or a product that does not like light; the natural white listings let an operator read a level through the wall instead. The last two rows are the size ladder on the same 90 inch circle, or nearly: 5100000N40 holds 2,600 gallons at 139 inches, giving back five inches of height for a batch that is barely smaller, and 8050000N40 holds 3,600 gallons on a 102 inch circle at 125 inches, trading floor for height in the other direction. Because the circle stays the same on the first five rows, you can move up and down that ladder without redrawing the pad, the bund or the aisle. If the 3,000 gallon decision is the live one, the complete buyer's guide for a 3000 gallon cone with a shallower angle is the long read, and the XLPE against HDPE comparison is the one to read if the shell material is the real question.

The manway on top and the lugs that get it there

• The opening on top: an 18 inch threaded vented manway at 144 inches plus the height of the stand. It is the only opening this sheet gives a size to, so the fill route is designed around it. Bring the line to a coupling at working level instead of asking anyone to carry a hose to the top of a twelve foot tank.
• Getting to it: the sheet lists ladder lugs on the shell, so the access can be drawn against the tank rather than improvised around it, and a platform or fixed ladder with a fall protection plan belongs in the same drawing as the structure.
• The vent: supplied with the manway on this sheet rather than as a separate item. On a tank being pumped down the air path is what protects the wall, so keep it clear and never blank it to control a smell.
• The outlet field: it reads 1 Manway / Lid, which names an opening and not a discharge. We print the field exactly as it reads and assert nothing further: no outlet dimension, no thread, no bulkhead and no valve. Tell us the line size, the valve type and the product, and we will confirm what this part number carries before anything is ordered.
• The cone: published at 30 degrees, a sensible middle angle for a free-flowing liquid and less generous with a product that packs. Below it, carry the valve, any reducer and the first run of pipe on steelwork off the stand, never on the tank, with a flexible connector at the first joint; 47,538 pounds of rated contents above a hanging valve is a problem waiting for a quiet weekend.
• What else the sheet counts, and what it leaves blank: 4 tiedown lugs, 8 lifting lugs and 2 flange lines are listed; no inlet, no warranty term and no NMFC number is published. Ratings are a specific gravity of 1.9, 25,020 pounds of water at 3,000 gallons, 47,538 pounds of max contents and 100 F / 37 C.

Where the tank stands over ground or a floor 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 route against the alternatives before a bund is poured around the wrong thing.

Dense product stored outdoors in a black shell

The pairing on this listing is specific: the 1.9 rating and a black wall. That points at heavy product standing outside, or heavy product that keeps better with daylight kept off it. Concentrated mineral and salt solutions in a tank farm, heavy liquid fertiliser and crop input blends at an agricultural retailer holding a season's volume outdoors, thickened sludge and settled solids at a treatment works, spent acid and pickling liquor at a metals plant, mineral and wash plant slurry, and batch make-up in chemical manufacturing where the vessel changes product and cannot leave a heel behind. The 30 degree cone is what makes the changeover quick: one low point, nothing standing in a corner, and a rinse rather than a recovery job at the end of a run. Two honest cautions go with the shape rather than the tank. The first is stratification, because 144 inches of liquid on a 90 inch circle separates more readily than a wide shallow vessel does, so the draw point and the mixing arrangement want planning together. The second is that a black wall gives you no view of the level at all, so the instrument is not optional here in the way it can be on a natural white tank. Settle the chemistry first in our chemical compatibility reference, because the gasket and valve answer comes from the product and not from the vessel.

Six hundred and seventy pounds, class 400, and the stand first

The freight class reads 400, a numeric class rather than a mode, no NMFC number is published, and the package is 90 inches by 90 inches by 144 inches at 670 pounds out of Lincoln, Nebraska. Price the lane to your ZIP with the freight cost estimator; the listed price is before freight. The sheet publishes no crane, no rigging, no permit and no escort detail, so none is described here; agree the offload equipment and the delivery window with us before the truck is booked. Have the stand set, levelled and anchored before the trailer turns up, because there is nowhere sensible to park a cone bottom tank while a foundation cures. Lift by the 8 lifting lugs the sheet lists, never by the manway, and keep the tank restrained the moment it is upright, since twelve feet of empty shell takes wind faster than anyone expects. Then prove the installation with clean water rather than product: hold the 25,020 pound load, walk the manway seal, the cone joint, the stand feet and the pad edge with a torch, and leave it standing full overnight before anything is connected. Check the anchor bolts and the strap tension again a week later, because ground settles under a new load and the fixing that was tight on day one is the one that is loose on day eight. Put the tank's part number on the maintenance log the day it lands; five years on, nobody remembers which shell it is.
