Snyder Industries 2000 Gallon XLPE Heavy Duty Cone Bottom Tank

What the 400 pound row carries that the 325 pound rows do not

This shell is listed four times and three of those listings weigh 325 pounds. This one weighs 400 pounds, and the sheet gives exactly one thing alongside that weight which changes what the tank can do: the specific gravity rating of 1.9, with 31,692 pounds of max contents where the lighter rows carry their own lower figure. The sheet offers no account of the weight difference itself, and this page invents none, so read the difference as the published allowance and nothing more. What that allowance buys is the right to fill this vessel with a product heavier than water instead of running a lighter tank part full, and that is a real operational difference rather than a specification flourish: a 2,000 gallon tank you can only fill part way is a smaller tank with a full sized footprint. Work out what your liquid weighs per gallon before you compare rows; if it is no heavier than water, one of the 325 pound listings is the honest buy and the difference stays with you. The colour field reads Black on this listing, which is the second half of the choice. A black wall keeps daylight out of the contents, which suits outdoor standing and product that reacts to light, and it costs you any view of the level through the wall, so the instrument stops being optional. Then the structure, which on a cone is never an accessory. There is no flat bottom here, the tank cannot stand on its own floor, and this sheet publishes no stand, no legs, no skirt, no support ring and no bolt pattern, so no stand height, rated load or material is stated on this page. What the support has to answer is on the sheet: 400 pounds of empty tank, 16,680 pounds of water and up to 31,692 pounds at the rating, arriving through a handful of stand feet inside a 90 inch circle rather than spread across a slab. Size the volume with the tank sizing calculator, take the freeboard from the tank sizing guide, and work the support out with the cone bottom tank stand compatibility matrix before a part number is fixed.

One 102 inch shell, four rows, two ratings

Two axes run through this table and keeping them separate is the whole skill of buying from it. The first axis is the rating, and it only has two values here: this row at 1.9 with 31,692 pounds of max contents, and the three 325 pound rows with their own lower figures for their own duties. Density decides that axis and nothing else should. The second axis is the colour field, which decides whether daylight reaches the contents and whether an operator can read a level through the wall. This row is the black one, so light stays out and the level gets read by instrument. The two axes are independent, which is why one shell needs four part numbers, and it is also why ordering from the gallon figure alone will eventually put the wrong tank on your pad. The bottom two rows are the size ladder rather than the grade ladder. 1910000N42 steps down to 1,650 gallons on an 86 inch circle at 94 inches, smaller in every direction and a genuine option when the real batch is smaller than the round number. 5110000N40 steps up to 2,500 gallons at 125 inches on this same 90 inch circle, buying volume out of height alone with no change to the pad. Where the crosslinked wall itself is the question rather than the shape or the rating, our read on XLPE against HDPE for chemistry duty sets out where crosslinking changes the answer and where it does not.

Vent, manway and the lugs the sheet counts

• The vent: it comes with the 18 inch threaded vented manway on this sheet rather than being specified separately, and on a tank being pumped down it is doing structural work. A vessel that cannot take air in takes the load in its wall instead. Keep the path clear, inspect it whenever the tank is opened, and never blank or wrap it to control a smell.
• The manway: 18 inches, threaded, at the top of 102 inches of shell plus the stand, with ladder lugs counted on the shell so the access can be drawn against the tank. Land the fill at a coupling at working level rather than asking anyone to take a hose up to the lid.
• The outlet field: it reads 1 Manway / Lid on this sheet. That names an opening and not a discharge, and this page prints the field as it reads and nothing more. No outlet dimension, no thread, no bulkhead and no valve is published or claimed. 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 and what hangs below it: published at 30 degrees, with the valve, any reducer and the first run of pipe carried on steelwork off the stand and never on the tank, plus a flexible connector at the first joint. Dense product is the point of this listing, so remember the suction behaves differently from water: size the pump on the actual specific gravity, and expect the last of a heavy batch to move more slowly than the first through the same line.
• What else the sheet dimensions: 4 tiedown lugs, 8 lifting lugs and 1 flange line. Plan the lift around the lifting lugs rather than around a sling position chosen at the kerb.
• Inlet, lid size, warranty and NMFC: none of the four is published and none is claimed. Published: a specific gravity rating of 1.9, 16,680 pounds of water at 2,000 gallons, 31,692 pounds of max contents and a service limit of 100 F / 37 C.

The black wall gives no view of the contents at all, so instrumentation is a specification item here: the level gauge selection guide for chemical service compares radar, ultrasonic, hydrostatic and magnetostrictive on the ways each fails rather than the way each sells. Where the tank stands over ground or a floor that would have to be recovered after a release, the Captor containment comparison answers containment separately from the tank.

Dense concentrate held in the dark

The pairing on this listing is specific and so are the buyers: a 1.9 rating and a black wall means heavy product that also wants to be kept out of the light, usually outdoors. Concentrated mineral and salt solutions in a process building or a tank farm, heavy liquid fertiliser and crop input concentrates at an agricultural retailer, treatment chemistry at working strength, brines, spent liquor and pickling solution at a metals plant, mineral and wash plant slurry, and process intermediates carrying solids in suspension that still have to drain clean between runs. The 31,692 pound allowance against 16,680 pounds of water is what makes those loads ordinary here rather than marginal, and the 30 degree cone is what stops the heaviest fraction becoming next week's problem: dense product left in the last inches of a flat floor is heavier, more valuable and more expensive to dispose of than a light one, so full-drain geometry pays back faster at high specific gravity than at low. Two honest cautions belong with the choice. The service limit on this sheet is 100 F / 37 C, and a hot fill or a black shell standing in strong sun is exactly where that figure stops being theoretical. And a tall column on a modest circle stratifies more readily than a wide shallow vessel, so plan the draw point and the mixing arrangement together if your product separates. Bring us the liquid, its specific gravity and its temperature at fill, and start the check in our chemical compatibility reference.

Four hundred pounds, a 102 inch package, class 400

This tank is moulded at Lincoln, Nebraska, and Nebraska is the origin state on the sheet, which puts the Midwest and the plains on the short lane and both coasts on the long one. The freight class reads 400, a numeric class beside an LTL ship mode, and the sheet publishes no NMFC number. The package measures 90 inches by 90 inches by 102 inches at 400 pounds, a large envelope carrying very little weight, and that is the shape that surprises people when the freight quote lands. Price the lane to your own ZIP with the freight cost estimator; the listed price is before freight. It arrives lying down and is stood up at your site, so agree who is doing that and with what before the truck is booked. The sheet publishes no crane, no rigging, no permit and no escort detail, and none is described here; settle the offload equipment and the delivery window with us in advance. Have the stand set, levelled and anchored first, because there is nowhere sensible to park a cone bottom tank while concrete cures. Lift by the 8 lifting lugs the sheet counts rather than by the manway, and restrain the shell as soon as it is vertical. Commission with clean water before product: hold the 16,680 pound water load, read the manway seal, the cone joint, the stand feet and the ground around the pad in that order, and leave it standing full overnight. Because this one will hold something heavier than water, do the water test properly first and then watch the stand feet again on the first full product fill, since that is the load the structure has never seen before. Keep a note of the date of that first fill with the site paperwork; every later inspection reads better against it. Walk the base after the first hard rain; a pad that shifts shows it at the edge first.
