Snyder Industries 1650 Gallon XLPE Heavy Duty Cone Bottom Tank

The duty: holding a full day's batch without leaving a heel

Sixteen hundred and fifty gallons is the size a plant buys when one batch has to cover a shift or a day rather than an hour. That changes the duty in a way worth being explicit about. At this volume the vessel is usually made up once, drawn down steadily against a process, and emptied before the next make-up, which means the thing that matters most is not how much it holds but how completely it gives it back. Liquid fertiliser and crop input blending at an agricultural retailer working through a season. Polymer, coagulant or lime solution make-up at a water or wastewater works dosing continuously. Batch preparation to a recipe in a manufacturing plant. Wash, rinse and recovery water that cycles through a working day. Buffer volume between two stages that will not run at the same rate. In all of them the residue at the changeover is a real number: 13,761 pounds of water is the full load, and whatever a flat bottomed vessel would leave in the last inches of it becomes somebody's rinse, pump or disposal problem. The sheet answers that with a published 30 degree cone rather than an angle read off a photograph. The shape puts it in a specific kind of building. The circle is 86 inches, a little over seven feet, and the shell stands 94 inches, seven feet ten inches. That is taller than the shorter tanks on the same circle and still nowhere near a column: it buys its extra volume by going up on a footprint that does not change. If you already have a smaller tank on this 86 inch circle, the floor work you did for it still applies, and what you need to re-check is the height. Stack it honestly: the stand, plus 94 inches of shell, plus the clearance above the opening on top for a person and a fill line, measured to the lowest fixed thing over the spot rather than to the roof. Below, leave the cone room to discharge into a pump, a tote, a drum or a drain, because that space is the whole point and it cannot be recovered once the structure is set. The structure is a separate purchase with its own lead time. This vessel has no flat floor, it cannot stand on its own bottom, and this sheet publishes no stand, no legs, no skirt, no support ring and no bolt pattern, so no stand height, load or material is stated here. It does publish the loads the structure carries: 300 pounds of empty tank, 13,761 pounds of water and 26,146 pounds at the rating, concentrated at stand feet inside an 86 inch circle rather than spread across a slab. That is engineered ground with a designed bearing area at each foot. Settle it with the cone bottom tank stand compatibility matrix before a part number is fixed, size the volume with the tank sizing calculator, and take the freeboard discipline from the tank sizing guide.

Four listings at sixteen fifty, plus a sixteen hundred and a two thousand

The top four rows are one shell: identical 1650 gallons, an identical 86 inch circle, an identical 94 inch height and an identical 300 pounds. Inside that group the decision is the colour and the material, and nothing else on the sheet separates them. This is the natural white listing, and 1910000N48 is the black one, which is a siting decision rather than a process one: where the tank sees daylight an opaque wall keeps light out of the contents, and where you want to read the level through the wall the translucent one earns its keep. SII-1910000N45 deserves reading rather than skimming, because Snyder's own name for it reads 30 Degree HDPE in white rather than cross-linked, so it is a different material question on the same dimensions, and we will not describe it as anything its name does not say. The bottom two rows are the genuinely interesting comparison. 8330000N42 holds 1600 gallons, only slightly less, but does it at 95 by 95 by 72 inches and 277 pounds: a wider circle and nearly two feet shorter. If your constraint is the roof, that is the tank, and the fifty gallons you give up is not the point. 5070000N40 goes the other way at 2000 gallons on a 90 by 90 circle at 102 inches and 325 pounds, more volume and more height again. Read the three together and this listing is the one that holds a substantial batch without widening the footprint you already have, which is exactly why it turns up on sites replacing a smaller tank in the same spot. Nothing on this sheet describes a wall thickness, a layer count or a construction difference between any of the listings, so this page describes none. Where the material is the real question, the article on when crosslinking matters for a chemistry duty settles it properly.

Thirty degrees, a seven inch manway, and the discharge left unnamed

• The drain: the sheet gives a 30 degree cone, so the fall to the low point is published rather than inferred. On a vessel holding 13,761 pounds of water that fall is the difference between a tank that empties and a tank that has to be washed out.
• The outlet field: it reads 1 Manway / Lid, which names an opening and not a discharge. It is printed here exactly as it reads. No outlet dimension, no thread, no bulkhead and no valve is published, so none is claimed. Tell us the line size, the valve type and the product, and we will confirm what this part number carries before an order is placed.
• Below the cone: valve, any reducer and the first run of pipe go on their own steelwork off the stand rather than on the tank, with a flexible connector at the first joint. Seven feet ten inches of full column puts real static head on that joint and a pump adds vibration to it.
• The opening on top: the manway field reads 7 in and gives nothing else, so no thread, vent arrangement or lid type is stated here. At 94 inches plus the height of the stand that opening is above head height in every installation, so 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.
• Structural detail: 4 tiedown lugs and 1 flange line is everything this record carries. No lifting lug, no ladder lug, no anchor specification and no bolt pattern is published, and none is stated.
• Ratings and blanks: a specific gravity rating of 1.9, 13,761 pounds of water at 1650 gallons, 26,146 pounds of max contents and a service limit of 100 F / 37 C. No inlet, no lid size, no warranty term and no NMFC number appears anywhere on the record.

On a vessel this deep the level instrument is the only honest picture of what is in the top of it, and fitting the wrong one costs more than choosing well did: the level gauge selection guide for chemical service compares radar, ultrasonic, hydrostatic and magnetostrictive on their failure modes rather than their brochures.

Process and blending duty where 13,761 pounds of water is the working load

Think of this size as a day tank rather than a batch tank, and the buying case comes into focus. An agricultural retailer blends a crop input in the morning and draws it down into applicators through the day. A treatment works makes up a dosing solution once a shift and meters it continuously. A manufacturer prepares an intermediate that feeds a line for as long as the line runs. A wash operation fills a recovery tank in the morning and empties it at the end. In each case the vessel is doing two jobs at once, holding enough to avoid a second make-up and emptying cleanly enough that the next product does not inherit the last one. The 30 degree cone on this sheet is what makes the second job possible, and the wide 86 inch circle helps in a way worth knowing: a squat vessel holds a blend together better than a tall slender one, so a product that wants to settle between draws gives less trouble in this shape. Two limits belong here stated plainly rather than buried. The 1.9 rating is a wall rating on this sheet and nothing more: it describes how dense a liquid the wall is rated to hold and says nothing about how your product behaves against polyethylene. Name the liquid, the concentration and the temperature it genuinely sits at through the year when you enquire, check it in our chemical compatibility reference before a gasket or a valve is chosen, and let the chemistry decide those rather than the tank. The service limit reads 100 F / 37 C, which is worth checking against any warm make-up before the order. The other question that is cheaper to settle now than later is what happens under the tank after a release, which is a site question rather than a tank question: the Captor containment comparison is the honest place to start it. Day to day, confirm every stand foot is bearing before the first fill and again after it, walk the full circle of the tank when you inspect, and keep a written record of what went in and when, because on a vessel that changes product the history is worth more than any single inspection.

Three hundred pounds, California and Nebraska on the sheet

This record names two plants, Chowchilla, California and Lincoln, Nebraska, and lists both California and Nebraska as shipping states, which is a genuine advantage on a package this shape: two origins means two lanes, and on a bulky moulded item the origin is most of the freight cost. Ask us which plant is supplying before you plan the lane. The freight class field reads 400, a numeric class rather than a mode, the ship mode reads LTL, and the sheet publishes no NMFC number. It shipments at 86 inches by 86 inches by 94 inches at 300 pounds, a large package at a moderate weight, which is normal on hollow moulded goods that fill trailer space without loading it. Price the lane to your own ZIP with the freight cost estimator; the listed price is before freight. It travels lying down and is stood up at your end, and that standing operation is the part of the day that goes wrong when nobody has planned it. This sheet publishes no crane, no rigging, no permit and no escort detail, so none is stated here; settle the offload equipment and the delivery window with us before the truck is booked. Set, level and anchor the stand first. Sling under the body rather than by the opening on top, and keep the tank restrained from the moment it is upright, because a seven foot circle of empty shell catches wind long before anyone expects it to. Then prove the installation with clean water rather than product: hold the 13,761 pound load, read the cone joint, the four tiedown lugs, the stand feet and the ground around the pad in that order, and leave it standing full overnight. What has moved by morning is almost never the tank, which is exactly why the overnight hold is worth the day it costs. Check the strap tension a week after the first fill; a tank settles a little, and the strap that was tight is loose.
