Snyder Industries 6000 Gallon XLPE Heavy Duty Cone Bottom Tank

Why the black heavy duty listing gets bought for a yard

Put the four 6,000 gallon listings side by side and cross out everything they share, because it is almost everything: one 142 inch circle, one 136 inch height, one 30 degree cone, one 18 inch threaded vented manway, 50,040 pounds of water, a limit of 100 F / 37 C, a freight class of 400 and the same material field. Two columns are left. Weight and rating put this tank and 5280200N42 at 1,250 pounds with a specific gravity rating of 1.9 and 95,076 pounds of max contents, while 5280200N40 and 5280200N46 are 1,100 pounds carrying their own lower rating and their own lower max contents figure on their own sheets. Colour splits each pair: this listing and 5280200N46 are black, the other two are Natural White. So the case for this particular part number is a product denser than water in a vessel that will stand where the sun reaches it, which is the ordinary outdoor bulk chemical position: a pad in a yard, a bunded area beside a loading point, a tank farm. A natural white shell is chosen for a different reason, being able to read a level through the wall, and that is normally an indoor argument. Neither the weight difference nor the colour difference is explained on any of these sheets, and no wall thickness, layer count or construction account is printed, so none is stated here. What is also not printed is a stand: no legs, no skirt, no support ring and no bolt pattern appear, and a cone bottom tank has no flat bottom to stand on, so the structure under it is a separate purchase with its own drawing and lead time. No stand height, rated load or stand material appears on this page for that reason. Take the question to the cone bottom tank stand compatibility matrix and confirm the fit with us against this part number. Underneath, the pad carries 1,250 pounds of empty tank, 50,040 pounds of water and 95,076 pounds at the rating through the feet of a stand rather than spread across a slab, which is why a cone foundation is engineered ground with a designed bearing area at each foot. The wide circle helps: feet further apart carry less each. Size the volume before the structure with the tank sizing calculator and the freeboard with the tank sizing guide.

The quad read by weight, and the two shapes beside it

Two shapes, six part numbers. The four squat rows hold 6,000 gallons on a 142 inch circle at 136 inches and differ only in weight, rating and colour. The two narrow rows hold their volume in height on a 90 inch circle: 5,500 gallons at 241 inches and 1,500 pounds, or 6,500 gallons at 273 inches and 2,100 pounds. For an outdoor installation the choice is not obvious until you think about wind and access, and then it usually is. A squat vessel presents less sail area, stands on feet that are further apart and carries less load at each of them, and everything on top of it is reachable from a shorter ladder. A slender column needs a more carefully drawn foundation, a more serious restraint arrangement and a working-at-height plan for every routine task. What the squat shell costs is ground: nearly twelve feet of circle, plus an aisle wide enough to work all the way round, plus room under the cone for whatever the discharge feeds. In a yard that is usually available and in a plant room it usually is not, which is how most of these decisions actually get made. One more point in favour of the wide shape if your product will not stay mixed: a shallow vessel stratifies less readily than a tall one. The longer version of this argument, written around this capacity, is here: the complete buyer's guide for a cone bottom tank at this capacity. If the resin choice is still open, crosslinked polyethylene against high density polyethylene for chemistry duty says when the crosslinking matters and when it is beside the point.

Access, venting and the drain the sheet does not size

• The vent: part of the 18 inch threaded vented manway on this sheet rather than a separate item. On a tank standing outdoors it sees weather as well as service, so it goes on the inspection round: keep it clear, look at it whenever the tank is opened, and never blank, tape or wrap it, however good the reason sounds at the time.
• The manway: 18 inches, threaded, at 136 inches plus the stand. A platform or fixed ladder with a fall protection plan belongs in the same drawing as the structure, and the fill belongs at a coupling at working level rather than at the top of the shell. The sheet notes ladder lugs and 1 flange line.
• No separate lid size field is published on this sheet, and none is claimed. The manway line is the whole of what it gives for access.
• The outlet: the sheet lists the outlet as 13. That is the field value, printed as written. It is not a pipe size, a thread or a valve and none of those is asserted. Give us the line size you need to land, the valve type and the product, and we will confirm what this part number carries before it ships.
• Below the cone: the valve, any reducer and the first length of pipe go on steelwork off the stand and never on the tank, with a flexible connector at the first joint so pump vibration stays out of the wall. With 95,076 pounds of rated contents above it, that joint carries enough without carrying hardware too.
• Blanks and ratings: no inlet, no warranty term and no NMFC number are published. The ratings given are a specific gravity of 1.9, 50,040 pounds of water at 6,000 gallons, 95,076 pounds of max contents, a 30 degree cone and a limit of 100 F / 37 C.

Because this listing is usually bought for an outdoor position, plan the restraint and the drainage around the pad at the same time as the fittings. A wide vessel standing on a stand in an open yard is exposed on every side, and the fixings that hold it are the ones nobody looks at again until a storm.

Outdoor bulk chemistry with a full drain every changeover

Black shell, a 1.9 rating, 95,076 pounds of max contents and a squat footprint: that combination goes to bulk chemical duty on a pad rather than to anything delicate indoors. Concentrated mineral and salt solutions held between truck drops, heavy liquid fertiliser and crop input blends at an agricultural retailer, spent liquor and pickling solution at a metals plant, thickened sludge and dewatering feed at a treatment works, mineral and wash plant slurry, and process intermediates carrying solids that still have to drain completely between runs. The 30 degree cone is the reason each of those works in a polyethylene vessel: nothing settles into a corner the tank cannot reach, and at 50,040 pounds of water a heel left on a flat floor is a disposal ticket rather than a nuisance. Two cautions belong with the position rather than the part number. The service limit is 100 F / 37 C, which is a real figure for a black tank in an open yard in summer, so think about where the sun sits over the spot before the pad is poured. And an outdoor vessel is read by people who never saw the purchase order, so the labelling and the level instrument deserve the same attention as the pipework. Check your liquid in our chemical compatibility reference before the gasket and valve are chosen, because the chemistry decides those and the tank does not.

A hundred and forty-two inches wide before the gate is measured

The width is the headline on this one and it is worth settling before anything else: 142 inches across, eleven feet ten inches, shipping at 142 inches by 142 inches by 136 inches and weighing 1,250 pounds. That is a package that takes trailer space rather than weight, and the place a wide shipment gets stuck is your gate, your yard or the turn into the compound, never the dock. Measure the route in before the truck is booked. The tank is moulded at Lincoln, Nebraska, with Nebraska given as the origin state, so the central lanes are short and either coast is long. The freight class reads 400, a numeric class rather than a mode, and no NMFC number is published. 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, and none is stated here; agree the offload equipment and the window with us before the booking rather than hoping a machine is free on the day. Set, level and anchor the stand before the trailer arrives, because there is nowhere sensible to park a vessel this wide while a foundation cures. Lift under the body with slings and never by the manway, and get the tank restrained as soon as it is standing. Prove it with clean water before any product: hold the 50,040 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. A photograph of the tank standing full on day one, filed with the site paperwork, settles every later argument about whether anything has moved. Keep one spare gasket for the outlet fitting on the shelf; it is the part that fails on a holiday.
