Snyder Industries 4100 Gallon XLPE Heavy Duty Cone Bottom Tank

The duty: dense batching where somebody has to see the level

Two requirements bring buyers to this exact part number, and they are worth separating. The first is weight per gallon. A 1.9 rating with 64,969 pounds of max contents in a vessel that holds 34,194 pounds of water means a liquid substantially heavier than water can fill the tank rather than half of it, and that is the difference between one vessel and two. The second is visibility. The natural white wall is translucent, so an operator on the walkway can see roughly where the liquid is without walking to an instrument, and on a tank that is filled and drawn down several times a week that saves a trip every time. Put them together and the buyer is usually a plant running concentrates on a schedule: agricultural retail making up crop inputs to order, a treatment works holding chemistry at working strength, a manufacturer batching to a recipe and washing down between products, a recovery system holding dense process liquid before it is drawn off. At 4,100 gallons this is the size people choose when 3,900 gallons stopped covering a delivery and 4,400 gallons would have meant a taller tank than the building allows; 197 inches is a real constraint in a lot of plant rooms. Then deal with the support, because a cone has no flat floor and cannot stand on its own bottom. This sheet publishes no stand, no legs, no skirt, no support ring and no bolt pattern, so the stand is a separate item with its own lead time, set and levelled before the tank arrives, and no height, rated load or material for one is stated here. The loads the structure has to take are 1,500 pounds of empty tank, 34,194 pounds of water and up to 64,969 pounds of rated contents, concentrated on a few stand feet inside a 90 inch circle rather than spread across a slab. Size the volume with the tank sizing calculator, take the freeboard discipline from the tank sizing guide, and settle the structure against the cone bottom tank stand compatibility matrix before you commit to either piece.

The 4100 quad, a 3900 under it and a 4400 over it

The first four rows are one shell, four times over: 4,100 gallons, a 90 inch circle, 197 inches tall. The sheet splits them on exactly two fields and no others. Weight and rating travel together, 1,500 pounds on this listing and on 5180000N48, 1,000 pounds on 5180000N40 and 5180000N46, and this page carries the 1.9 rating with 64,969 pounds of max contents. Colour is the other split, natural white here and on 5180000N40, black on the other two. So the quad is really a two-by-two: pick the rating your product needs, then pick whether you want daylight kept out of the tank or a level you can see through the wall. This listing is the white one at the higher rating, which is the combination for dense product that gets watched. No account of the weight difference between the pairs appears on the sheet, so none is offered here beyond the published figures. The last two rows are the sizes either side on the same circle: 5440000N40 at 3,900 gallons in 180 inches, seventeen inches shorter and worth a look when headroom is tight, and 5200000N42 at 4,400 gallons in 200 inches, which is the step up when a delivery no longer fits. The circle does not change across any of those, so the floor plan stays the same and only the height moves. Where the crosslinked wall itself is the question rather than the size, our read on XLPE against HDPE for chemistry duty sets out where crosslinking earns its place.

Everything hangs off the low point: the fittings this sheet names

• The discharge first, because on a cone it is the lowest point of the vessel and the whole design leans on it. The outlet field on this sheet reads 1 Manway / Lid. That names an opening and not a discharge, and it is printed here exactly as it reads instead of being converted into a pipe size. No outlet dimension, thread, bulkhead or valve is published, so none is stated. Give us the line size, the valve type and the product and we will confirm what 5180000N42 carries before anything is ordered.
• Carrying the weight: with up to 64,969 pounds of rated contents standing above it, nothing at the low point should hang from the tank. Support the valve, any reducer and the first run of pipe on steelwork off the stand, and use a flexible connector at the first joint so pump vibration never reaches the wall.
• Pumping a dense liquid: a 1.9 rated product does not behave like water at the suction. Size the pump on the actual weight per gallon rather than on the gallon figure, keep the run off the cone short and straight, and expect the last of a dense batch to move more slowly than the first through the same line.
• Cone angle: this sheet publishes no cone angle field and the product name carries none, so no angle is stated here. If the angle is decisive for your product, ask us to check the part number rather than reading it off a photograph.
• Access on top: an 18 inch threaded vented manway at the top of 197 inches of shell plus the stand. The vent arrives with the manway rather than as a separate item. Keep it clear at all times, because a vessel being pumped down that cannot take air in takes the load in its own wall instead.
• Absent from this sheet, and therefore absent from this page: the inlet, the lid size, any lug or flange count, the warranty term and the NMFC number. Present: a specific gravity of 1.9, 34,194 pounds of water at 4,100 gallons, 64,969 pounds of max contents and a limit of 100 F / 37 C.

The translucent wall gives you a rough level in good light and nothing at all at night or in a dark plant room, so instrumentation is still a specification item on a 197 inch column: the level gauge selection guide for chemical service compares the four common technologies on exactly this duty. Where the tank stands over ground, a floor or a drain that would have to be recovered after a release, the Captor containment comparison answers the containment question separately from the tank question.

Concentrate handling and make-up at a working plant

Density is what this listing sells, so the duty follows the density. Concentrated crop inputs and fertiliser blends at an agricultural retailer, treatment chemistry held at working strength at a water or wastewater works, brines, dense process concentrates in manufacturing, and recovered liquid waiting on a decision about where it goes next. The arithmetic is the same in all of them: 4,100 gallons is 34,194 pounds of water, and the sheet allows 64,969 pounds of contents, so the extra allowance is what lets a heavy liquid fill the tank instead of half filling it. Work out what your product weighs per gallon before you compare part numbers, because that single figure moves this decision further than price does. The white wall is the second reason people land here rather than on the black listing at the same weight, and it earns its place on a vessel that is filled and drawn down often, where a glance from the walkway replaces a walk to a gauge. The cone is the third and the quiet one: dense material left in the bottom of a flat tank is heavier, more valuable and more expensive to dispose of than light material, so full-drain geometry pays back faster at high specific gravity than at low. Two honest limitations. Sunlight passes through a translucent wall, which is a housekeeping problem in water-based product standing outdoors, and the black listing exists for exactly that reason. And the published service limit is 100 F / 37 C, lower than many Snyder vertical sheets carry, so a warm fill or an exposed pad deserves a conversation before you order. Our chemical compatibility database is the first place to take that question, product by product.

Fifteen hundred pounds, 197 inches, class 300

This tank is moulded at Lincoln, Nebraska and the sheet gives Nebraska as the shipping state, so lane cost falls out of how far you sit from the middle of the country. The class reads 300 beside an LTL ship mode and no NMFC number is published. It moves at 90 by 90 by 197 inches and 1,500 pounds, a light load filling a lot of trailer, which is why a tank like this is quoted on the room it takes rather than on the scale ticket. Put your ZIP into the freight cost estimator for the lane figure; the listed price is before freight. It arrives 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 lifting lugs and no tiedown lugs, so assume none: lift under the body, never off the manway, and agree the method with us in advance. No crane, rigging, permit or escort detail is published either, so none is described here; settle the offload equipment and the delivery window before the truck is booked. The stand goes in first, set, levelled and anchored, because a cone bottom tank with nothing to stand on is a tank lying in your yard taking the space you needed. Commission with clean water rather than with product, take it to the 34,194 pound water load, then read the manway seal, the cone joint, the stand feet and the pad edge in that order and leave it standing full overnight. A translucent wall is a gift during that test: run it in daylight and you will see a level change that a gauge might round away. A photo of the tank on its pad, full, on day one is worth keeping; it is the baseline every later inspection is compared against.
