Snyder Industries 3900 Gallon XLPE Heavy Duty Cone Bottom Tank

Outdoor ground, indoor ceiling, and the structure in between

Where this tank sits changes what you have to solve, and a black shell usually means outdoors. Take the outdoor case first. There is no floor to rest on: a cone bottom vessel has no flat bottom, and this sheet publishes no stand, no legs, no skirt, no support ring and no bolt pattern, so the support is a separate item designed, built and anchored before the tank arrives, and no stand height, rated load or stand material appears on this page. Outdoors, the stand is also the wind and restraint answer, because 180 inches of shell standing empty on a pad is a sail before it is a tank, and the day to deal with that is the day the structure is drawn rather than the day the wind gets up. The pad underneath takes 1,400 pounds of empty tank, a published full water weight of 32,526 pounds and 61,799 pounds at the rating, and it takes all of it through the feet of the stand inside a 90 inch circle rather than across a slab. Designed ground with a bearing area at every foot, level and uniform, is what that needs, and on a dense product it is not a place to save money. Indoors the constraint flips from wind to ceiling. Your finished height is the stand, plus 180 inches of shell, plus clearance above the manway for a person and a fill line, and separately the room under the cone for whatever the discharge feeds. Measure to the lowest fixed obstruction over the spot and work down; if the total does not clear, the honest fix is a shorter shell rather than a shorter stand, because clearance underneath is the whole point of a cone. Work the support out with the stand compatibility matrix, size the volume with the tank sizing calculator, and take the freeboard from the tank sizing guide before the concrete is ordered.

Four listings on one shell, two capacities either side

Two questions run through this table and they are worth separating. The first is how dense your product is. This listing is rated at a specific gravity of 1.9 with 61,799 pounds of max contents, and the 1,100 pound standard listings carry their own lower figures for their own duties. Match the rating to the product and stop there; buying above your duty buys nothing you will ever load. The second is where the tank stands, and that is what the colour column is really about. This one is black, which keeps daylight off the contents, and it is the usual answer for a vessel standing in the open or holding something that does not want light. The natural white listings are the answer where an operator wants to read a level through the wall. Neither is better; they solve different problems and the sheet prices them as separate part numbers. The two outer rows are the size ladder. 5180000N40 holds 4,100 gallons at 197 inches on the same 90 inch circle, buying volume with height rather than floor. 8050000N40 holds 3,600 gallons on a 102 inch circle at 125 inches, buying it with floor rather than height. Where the roof is fixed, that last row is often the only one that fits, and it is worth measuring before the argument starts. If the reason you are choosing a crosslinked shell at all is the chemistry rather than the shape, the XLPE against HDPE comparison is the read that settles it.

Two rows look the same? The difference is the wall; call 866-418-1777 with the liquid and we will say which, or ask for a quote on both.

The discharge this sheet does not dimension

• The outlet field: it reads 1 Manway / Lid on this sheet, 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.
• Under the cone: the valve, any reducer and the first length 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. At 61,799 pounds of rated contents the static head at the low point of a full column is unforgiving of a hanging valve.
• The cone angle: this sheet publishes none and the product name carries none, so this page states none. If the drainage behaviour of a settling product is what decides your purchase, ask us to confirm the geometry against the part number.
• Access on top: an 18 inch threaded vented manway at 180 inches plus the stand, which is well above head height in every installation. A platform or fixed ladder with a fall protection plan belongs in the same drawing as the structure, and the fill should land at a coupling at working level instead of asking anyone to carry a hose up there.
• The vent: it comes 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, inspect it whenever the tank is opened, and never blank it to control a smell.
• Inlet, structural detail, warranty and NMFC: none of the four is published on this sheet and none is claimed here. Ratings are a specific gravity of 1.9, a published full water weight of 32,526 pounds at 3,900 gallons, 61,799 pounds of max contents and 100 F / 37 C.

Two questions are cheaper to settle now than later. How the level is read, because on a vessel this deep a confident wrong number is worse than no number: the level gauge selection guide compares the technologies on their failure modes. And what happens under it after a release, which is a containment question rather than a tank question: the Captor containment comparison sets the contained route against the alternatives before a bund is poured around the wrong thing.

Dense product outdoors, with light kept off the contents

The combination on this listing is specific: a 1.9 rating and a black shell. That points at heavy product standing outside, or heavy product that does not want daylight through the wall. 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 dewatering feed at a treatment works, spent acid and pickling liquor at a metals plant, mineral and wash plant slurry, and process intermediates that carry solids and still have to drain clean at the end of a run. The cone is the reason all of those work at this size: one low point, nothing left standing in a corner, and a changeover that is a rinse rather than an excavation. Two honest cautions belong with the shape rather than the tank. The first is stratification, because 180 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 sometimes is on a natural white tank. Start from the chemistry rather than the shape and check the product in our chemical compatibility reference before a gasket or a valve is chosen.

Class 300 out of Nebraska on a fifteen foot package

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. The freight class reads 300, a numeric class rather than a mode, and the sheet publishes no NMFC number. The package measures 90 inches by 90 inches by 180 inches at 1,400 pounds, which is trailer length rather than payload, and length is what prices this movement. Price your own ZIP with the freight cost estimator; the listed price is before freight. The shell travels lying down and is stood up at your site, and standing a fifteen foot vessel is a planned operation with a machine and a nominated person rather than something improvised when the truck arrives. The sheet publishes no crane, no rigging, no permit and no escort detail, so this page describes no lift; agree the offload equipment and the 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 under the body, never by the manway, and keep the tank restrained the moment it is upright. Prove the whole installation with clean water rather than product: hold the water 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. A photograph of it standing full on day one, filed with the site paperwork, settles every later argument about whether something has moved. Mark the vent and the outlet on the outside of the shell so nobody caps the wrong one in the dark.
