Snyder Industries 1250 Gallon XLPE Heavy Duty Cone Bottom Tank

The duty first: short-cycle batching where the wide circle beats the tall column

Start with the work this tank is bought to do, because the shape only makes sense once the duty is on the table. At 1250 gallons a cone bottom vessel is almost never a storage tank. It is a working tank: something is made up in it, held for a while, drawn off completely, and the same thing happens again tomorrow. Liquid fertiliser and crop input blending at an agricultural retailer. Polymer and coagulant make-up at a water or wastewater works. Batch preparation to a recipe in a manufacturing plant. Wash and rinse systems that have to change product without carrying the last one forward. In every one of those the cone earns its price at the changeover rather than during the run, because the vessel keeps draining toward one low point instead of leaving a ring of product on a flat floor for somebody to shovel, pump or explain. At 10,425 pounds of water a heel is a disposal ticket, not a nuisance. Now the shape, which is what separates this listing from the taller cones beside it. This is a squat tank: 95 inches across and only 70 inches tall, seven feet eleven inches of circle under five feet ten inches of shell. That trade buys volume out of floor area rather than out of ceiling, and there are two reasons a plant chooses it. The first is headroom. Everything a stand adds goes underneath those 70 inches, so a low building, a duct run, a crane rail or a mezzanine over the spot decides the purchase long before the price does. The second is behaviour: a wide, short column holds a blend together better than a tall slender one, so a product that wants to separate between batches gives less trouble in this shell. What holds it up is a separate purchase, and that is the part people under-build. There is no flat floor on this tank. 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 this page prints none. The support is specified, set, levelled and anchored before the tank arrives. What the sheet does give you is the envelope and the loads an engineer will ask for first: 300 pounds of empty tank, 10,425 pounds of water and 19,808 pounds at the rating, all arriving at a handful of stand feet inside a 95 inch circle rather than spreading across a slab the way a flat bottomed tank spreads them. The wide circle helps here, because feet set further apart carry less each. Settle the support properly against the cone bottom tank stand compatibility matrix before a part number is fixed, size the volume honestly with the tank sizing calculator, and take the freeboard discipline from the tank sizing guide, because a product that warms or gasses needs headspace a tape measure will not give you.

Four part numbers on this shell, and two smaller cones on the same sheet

Cover the part numbers and the top four rows are one object: identical gallons, an identical 95 inch circle, an identical 70 inch height and an identical 300 pounds. What separates them is what each of those four records publishes on its own page, and this one publishes a specific gravity rating of 1.9 with 19,808 pounds of max contents. Nothing on this sheet describes a wall thickness, a layer count or a construction difference between the four, so this page describes none, and anybody who tells you otherwise from a catalogue photograph is guessing. If the colour or the rating on one of the other three is what you need, take the part number to us and we will confirm what that record carries in writing before an order is placed. The two lower rows are the real selection question, and they both sit on the narrower 86 inch circle. 1890000N42 holds 1000 gallons at 86 by 86 by 66 inches and 210 pounds: nine inches less circle in each direction and four inches shorter, which is the answer when the footprint is the constraint rather than the roof. 1900000N42 holds 1400 gallons on that same 86 inch circle but stands 80 inches at 245 pounds, so it buys more volume by going up rather than out. Read the three together and this tank is the wide one. It holds more than the 1000 and less than the 1400, and it does it in the shortest shell of the three, which is exactly the trade a low building forces. Where the material question is the one that actually decides the purchase, the article on when crosslinking matters for a chemistry duty settles it better than a product page can.

The drain the sheet does not size, and the eighteen inch manway above it

• The drain path, which is the whole point of the shape: on a cone the discharge is the lowest point of the vessel and everything hangs off it. The outlet field on this sheet reads 1 Manway / Lid, which names an opening rather than a discharge, and it is printed here exactly as it reads rather than turned into a pipe size. No outlet dimension, no thread, no bulkhead and no valve is published, so none is claimed. Tell us the line size you need to land, the valve type and the product, and we will confirm what this part number carries before anything is ordered.
• Carrying the discharge: whatever is fitted, the valve, any reducer and the first run of pipe belong on their own 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 19,808 pounds of rated contents standing above it, the bottom of a full column is the wrong place for dead weight.
• The cone angle: this record publishes no cone angle field and the product name carries none, so this page states none. If the way your product slides is what decides the purchase, ask and we will confirm the geometry against the part number rather than reading it off a photograph.
• Access on top: an 18 inch threaded vented manway at 70 inches plus the height of the stand, which is above head height in most installations. A platform or fixed ladder with a fall protection plan belongs in the same drawing as the structure, and the fill line belongs at a coupling at working level rather than up a ladder in somebody's hand.
• The vent: it arrives with the manway on this sheet rather than as a separately specified item. On a tank being drawn down by pump the air path is what protects the wall, so keep it clear, look at it every time the manway is opened, and never blank, tape or wrap it to control a smell.
• Ratings and blanks: a specific gravity rating of 1.9, 10,425 pounds of water at 1250 gallons, 19,808 pounds of max contents and a service limit of 100 F / 37 C. No inlet, no lid size, no warranty term, no NMFC number and no structural lug or flange detail is published on this record, and none is stated.

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

Who buys a squat twelve fifty, and what the job looks like

The buyer for this one is usually somebody whose building decided the specification. A greenhouse or nursery range with low eaves and a feed system that has to empty between crops. An agricultural retail yard filling applicator tanks out of a blend that changes through the season. A treatment works making up polymer in a plant room with pipework already at head height. A food, beverage or process plant batching to a recipe and rinsing between products. A wash bay or vehicle wash recovering and re-dosing water. In every case the working day looks the same: fill, hold, draw off, rinse, repeat, with somebody accountable for what is left in the tank at the end of it. That is the argument for 70 inches of shell and 95 inches of circle. The tank goes where a taller one would not, and the batch still leaves by one point. Two cautions belong here and both are about honesty rather than caution for its own sake. The first is that 1.9 is a wall rating on this sheet and nothing more. It says how dense a liquid the wall is rated to hold; it says nothing at all about how your particular product behaves against polyethylene, and we will not pretend otherwise from a product page. Name the liquid, the concentration and the temperature it genuinely sits at through the year when you enquire, look it up in our chemical compatibility reference before a gasket or a valve is chosen, and let the chemistry decide those rather than the tank. The second is containment. What happens under a cone bottom tank after a release is a site question rather than a tank question, and it is cheaper to settle on paper than after an incident: the Captor containment comparison is the honest place to start it. Day to day, the habits that keep a cone honest are dull. Confirm every stand foot is bearing before the first fill and again after it. Walk the full circle of the tank when you inspect it, because eight feet of shell means nobody sees the far side from where they are standing. Read the manway seal and the cone joint in daylight rather than under a torch. And keep a record of what went in the tank and when, because on a vessel that changes product the history is worth more than any single inspection.

Three hundred pounds out of Marked Tree on a class 400 ticket

This tank is moulded at Marked Tree, Arkansas, and Arkansas is the only shipping state on the record, which puts the mid-South on a short lane and both coasts on a planned one. 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 95 inches by 95 inches by 70 inches at 300 pounds, which is a large package at a modest weight, and that combination 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 somebody stands it 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; agree the offload equipment and the delivery window with us before the truck is booked. Have the stand set, levelled and anchored first, because a cone bottom tank with nowhere to stand is a tank lying in your yard in the space you needed. Sling under the body, never by the manway, and keep it restrained from the moment it is upright, because an empty shell nearly eight feet across takes wind at a speed that surprises people. Then prove the installation with clean water rather than with product: hold the 10,425 pound load, read the manway seal, the cone joint, the stand feet and the pad edge in that order, and leave it standing full overnight before anything is connected. Photograph the tank standing full on day one and file the photograph with the paperwork. It settles every later argument about whether something has moved, and it costs nothing on the day. Photograph the outlet fitting from below before the pipe goes on; a slow weep is easier to compare against than to describe.
