Snyder Industries 2600 Gallon Black XLPE Heavy Duty Cone Bottom Tank

Outdoor ground, indoor ceiling, and the structure between them

Where this tank stands 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 139 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 570 pounds of empty tank, 21,684 pounds of water and up to 41,200 pounds of rated contents, 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 economise. Indoors the constraint flips from wind to ceiling. The finished height is the stand, plus 139 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 reason you are buying a cone at all. Either way, leave an aisle all the way round while it is still free to do so. Work the support out with the cone bottom tank 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.

The black listing and the white ones on the 2600 shell

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 41,200 pounds of max contents against 21,684 pounds of water in the same 2,600 gallons, which is what lets you fill the vessel with a heavy product instead of with headroom. The 500 pound listings carry their own lower figures for their own duties, and buying above your duty buys paperwork rather than capability. The second question 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 rough level through the wall. Neither is better; they solve different problems, and the pairing on this row, dense product kept dark, is a specific combination rather than a general upgrade. The two outer rows are the size ladder on the same 90 inch circle, which means the pad, the bund and the aisle do not change when you move along it: 5110000N40 at 2,500 gallons and 125 inches hands back over a foot of height, and 5150000N40 at 3,000 gallons and 144 inches costs five inches more. Where the roof is fixed, that comparison is worth making with a tape measure before the argument about capacity 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.

One low point, and a sheet that stops short of sizing it

• 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 5100000N48 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 up to 41,200 pounds of rated contents, the static head at the low point of a full column is unforgiving of a hanging valve.
• Dense product 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 straight, and expect the last of a dense batch to move more slowly than the first through the same line.
• 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 139 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 comes with the manway rather than as a separate item, so keep it clear.
• Inlet, lid size, structural detail, warranty and NMFC: none of the five is published on this sheet and none is claimed. Published: a specific gravity rating of 1.9, 21,684 pounds of water at 2,600 gallons, 41,200 pounds of max contents and 100 F / 37 C.

A black wall gives an operator no view of the level at all, so the instrument carries the whole job here: the level gauge selection guide compares radar, ultrasonic, hydrostatic and magnetostrictive on the ways each one fails rather than the way each one sells. And where the tank stands over ground that would have to be recovered after a release, the Captor containment comparison sets the contained route against the alternatives before a bund is poured around the wrong thing.

Dense product kept out of daylight

The combination on this listing is specific: a 1.9 rating and a black shell at 2,600 gallons. 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 139 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, so instrumentation is not optional here in the way it sometimes is on a natural white tank. The sheet's service limit of 100 F / 37 C is worth holding on to as well, because a black shell in open sun and a warm fill are the two things that press on it. 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 400, Lincoln origin, and the day it stands up

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 400 beside an LTL ship mode, and the sheet publishes no NMFC number. The shipped package measures 90 inches by 90 inches by 139 inches at 570 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 an eleven and a half foot vessel is a planned operation with a machine and a nominated person rather than something improvised when the truck arrives. This sheet publishes no lug count, so plan the lift under the body rather than around a lifting point nobody has confirmed, and never off the manway. No crane, rigging, permit or escort detail is published either, 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, and keep the tank restrained the moment it is upright. Prove the whole installation with clean water rather than product: hold the 21,684 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. A photograph of it standing full on day one, filed with the site paperwork, settles every later argument about whether something has moved. Keep the first delivery's paperwork with the tank; strength and date on day one is the baseline for every batch after.
