7400 Gallon Cone Bottom Tank

What a lighter-rated seven thousand four hundred is bought to hold

Begin with the duty, because the rating on this listing is what shapes it. The wall here is rated to a specific gravity of 1.5, and the sheet pairs that with 92,574 pounds of max contents. That is the honest ceiling on how dense a liquid the wall is rated to hold, and it points the listing squarely at bulk duties where the product is water or close to it rather than at the densest end of the catalogue. Bulk process and service water held at a plant. Rainwater, wash water or recovered water stored before treatment or reuse. Liquid feed, blend and make-up volumes prepared and drawn down through a season. Suspensions and process liquors where the cone is there because solids have to keep moving to a point rather than settling out across a floor. Buffer volume between two stages that run at different rates and must be genuinely empty at the end of a campaign. In every one of them the reason for a cone at 7400 gallons is the same: at 61,716 pounds of water, whatever a flat bottom leaves behind is a real volume that somebody has to pump out, dispose of, or find in the next batch. The envelope is the other half of the specification and the record is sparing with it. It gives a diameter of 142 inches, eleven feet ten inches, and a height of 160 inches, thirteen feet four inches. It publishes no length and no width, so none is quoted here. Those two figures are enough to begin the civil design and not enough to finish it, which is why the support drawing is a conversation rather than a download. The support itself is a separate purchase on every cone listing, including this one. The vessel has no flat floor and 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. What it does publish is the load: 1600 pounds of empty tank, 61,716 pounds of water and 92,574 pounds at the rating, all arriving at the feet of a structure inside a 142 inch circle rather than spreading across a slab. That is an engineered foundation and an engineered frame, complete and signed off before the tank is on site. Stack the finished height too: the structure, plus 160 inches of shell, plus the clearance above an 18 inch manway for a person and a fill line, measured to the lowest fixed thing over the spot rather than to the roof. Size the usable volume with the tank sizing calculator and take the freeboard discipline from the tank sizing guide before the structural drawing is fixed.

The rating that separates this listing from the other three

Four part numbers hold 7400 gallons on this shell, and what actually separates this one from the others is the rating rather than the shape. This record carries a specific gravity rating of 1.5 and 92,574 pounds of max contents, and it is listed at 1600 pounds empty; the two heavy duty listings on this shell carry a higher specific gravity rating and a heavier empty weight on their own records. Each of those pages cites its own figures and this page cites only its own, which is the only honest way to print a family where the records disagree. Choose on the rating your product actually needs, not on the shell they share. The record is also uneven about the family and the table shows it as it reads. SII-5320100N43 is the only row carrying a full envelope, at 142 by 142 by 160 inches and 1600 pounds. SII-5320100N45 and SII-5320100N51 carry a 160 inch height and no other dimension and no weight, and those cells are left blank here rather than filled in from a neighbouring row. Send us any of those part numbers and we will confirm in writing what that record carries before an order is placed. The bottom two rows are about the building rather than the chemistry. 7180000N40 holds 6500 gallons on a 90 inch circle at 273 inches, a narrow column well over twice this tank's height, which saves ground and costs headroom and foundation design. 5340100N40 holds 11500 gallons on this same 142 inch circle at 215 inches and 2850 pounds, buying volume upward on a footprint that does not change. This listing is the shortest of the three on the larger circle, which is the right answer where overhead clearance is the constraint. Where the outlet rather than the shell will decide whether the cone actually empties, especially in a solids-bearing service, the cone outlet sizing article covers the geometry and the drain-time arithmetic properly.

The drain path, the top opening, and the sizes never published

• The discharge: the lowest point of the vessel is a single spot and 7400 gallons keeps running toward it. That is the entire reason for the shape, and it is the difference between a rinse and a tanker load of residue at the end of a campaign.
• The outlet: the field on this record is empty. No outlet dimension, no thread, no bulkhead and no valve is published, so none is claimed here. At this volume settle it first rather than last: 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.
• The inlet: also blank on this sheet. The fill arrangement is not published and is not described here.
• The cone angle: this record carries no cone angle field and this listing's name carries none either, so this page states none and does not read one across from another listing's name.
• Carrying the pipework: valve, reducer and the first run of pipe belong on their own steelwork off the structure and never on the tank, with a flexible connector at the first joint so pump vibration stays out of the wall. With 92,574 pounds of rated contents standing above it, nothing should hang off the bottom of a full column.
• Access on top: an 18 inch threaded vented manway at 160 inches plus the height of the structure. That is a working-at-height job in every installation, so the platform, the fixed ladder and the fall protection plan belong in the same drawing as the frame, and the fill line belongs at a coupling at working level.
• The vent: it comes with the manway on this sheet rather than as a separate item. On a tank being drawn down by pump the air path is the wall's protection, so keep it clear, look at it whenever the manway is opened, and never blank, tape or wrap it.
• Ratings and blanks: a specific gravity rating of 1.5, 61,716 pounds of water at 7400 gallons and 92,574 pounds of max contents. No service limit, no lid size, no warranty term, no certification entry, no NMFC number and no structural detail appears on this record.

Two links belong with this list rather than in a footer, because both decisions are made before anything is drilled: the top fitting placement article sets out where the fill, the vent, the gauge and the drain should sit relative to one another, and the level gauge selection guide compares the instrument technologies on how they fail rather than on how they are marketed.

Bulk water, process holding and the honest limits on this record

This listing suits the bulk duties at the lighter end of the density range, which covers a great deal of what a large cone actually holds. Process and service water at an industrial plant. Recovered wash water, rainwater or reuse volume held before or after treatment. Liquid feed and blend volumes at an agricultural retail or custom application yard, made up and drawn down through a season. Process liquors and suspensions where the cone is there because solids settle and have to keep moving toward the low point. Buffer and surge volume between two stages of a plant that run at different rates. A large wash or recovery system that cycles enough volume to need one vessel rather than three. In each case the buying decision is really two decisions: how much volume, and how dense the product is. This record answers the second with a specific gravity rating of 1.5 and 92,574 pounds of max contents, and that figure is the right place to start rather than an afterthought. Two honest limits, because the rating is only half the story. A specific gravity rating describes how dense a liquid the wall is rated to hold. It says nothing at all about how your particular product behaves against polyethylene, and no product page should imply otherwise. 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, a seal or a valve is specified, and let the chemistry decide those rather than the tank. The second is temperature: this record publishes no service limit at all, so this page states none. If your product is held warm, or the vessel stands in full sun through a long summer, ask us with the numbers rather than assuming a figure from a neighbouring listing. On the routine at this scale, the discipline is about access and records. Confirm every support foot is bearing before the first fill and again after it. Walk the full circle at every inspection, because on a vessel nearly twelve feet across 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, keep the vent on the same round, and keep a written record of what the tank has held and when.

Sixteen hundred pounds, Lincoln, Nebraska, class three hundred

This tank is moulded at Lincoln, Nebraska, and Nebraska is the shipping state on the record, which makes the central plains the short lane and either coast a planned one. The freight class field reads 300, a numeric class rather than a mode, the ship mode reads LTL, and the sheet publishes no NMFC number. It ships at 1600 pounds in an envelope 142 inches across and 160 inches tall, which is a very large item at a modest weight and the reason a vessel like this is priced on the space it occupies rather than on what it weighs. 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 is the part of the project that goes wrong when it has not been planned. This sheet publishes no crane, no rigging, no permit and no escort detail, so none is stated here; agree the offload equipment, the access route and the delivery window with us before the truck is booked. Have the foundation and the support structure finished, levelled and signed off first, because a vessel this size with nowhere to stand ends up occupying the yard it was meant to stand in. Sling under the body rather than by the manway, and keep it restrained from the moment it is upright; an empty shell thirteen feet four inches tall catches wind long before anyone expects it to. Then prove the installation with clean water rather than with product: hold the 61,716 pound load, read the manway seal, the cone joint, the structure feet and the ground around them in that order, in daylight, and leave it standing full overnight before a single line is connected. Check the label against the part number you ordered before anything is uncrated, because the four listings on this shell are told apart by their numbers and their ratings rather than by their photographs. Keep the delivery paperwork with the tank; the serial number on the shell is what a warranty claim starts from.
