Snyder Industries 4100 Gallon XLPE Cone Bottom Tank

Buying the rating your product actually needs

The duty here is the ordinary one, which is also the most common one: several thousand gallons of liquid no denser than water, turned over regularly, and emptied completely every time. Process and treated water holding, rinse and wash water between product changes, polymer and coagulant make-up at a treatment works, liquid feed and crop input blending at agricultural retail, buffer volume between two stages of a plant running at different rates. For all of those the cone is what you are paying for and the density rating is not. This sheet rates the wall at 1.5 with 51,291 pounds of max contents against 34,194 pounds of water at 4,100 gallons, which is the wall that matches the job. The heavier listings on the same sheet exist for products that weigh appreciably more per gallon than water, and buying that allowance for water is buying a number nobody will ever load. So do the weight-per-gallon arithmetic on your own product first; it settles this page against its own siblings faster than anything else. The other half of the decision is where the vessel goes. A cone 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 the stand is a separate item ordered on its own lead time and set before the tank arrives. No stand height, rated load or material is stated here because none is published. Plan the finished height as the stand plus 197 inches plus working clearance over the manway, and in a building measure to the lowest fixed thing over the spot rather than to the ridge, because a sprinkler main or a duct run decides this more often than the roof does. Plan the loads as 1,000 pounds of empty tank, 34,194 pounds of water and up to 51,291 pounds of rated contents on a few stand feet inside a 90 inch circle. Fix the volume with the tank sizing calculator, take the freeboard rule from the tank sizing guide, and work the support out against the cone bottom tank stand compatibility matrix.

Two weights and two ratings across four 4100 listings

Read the top four rows as a grid rather than a list. One shell, 4,100 gallons, 90 inch circle, 197 inches tall, and two fields moving across it. Empty weight and rating move together: 1,000 pounds and a 1.5 rating on this listing and on 5180000N46, 1,500 pounds on the two the maker calls heavy duty. Colour moves independently: natural white here and on 5180000N42, black on the other two. That gives you four combinations of the same tank, and the sensible way to buy is to fix the rating from your product's weight per gallon first and the colour from where the tank stands second. This listing is the white one at 1.5, which is the light end of the grid and, for water-like product indoors, the right end. One row in this family is worth a second look for a different reason: 5440000N40 at 3,900 gallons is 1,100 pounds, a hundred pounds heavier than this tank while holding two hundred gallons less, and it stands only 180 inches tall. The sheet explains none of that and neither will we; what it means in practice is that under a low roof the shorter tank is on the table even though it holds less. 5200000N42 goes the other way at 4,400 gallons and 200 inches. The circle never changes across any of them, so the floor plan is fixed and height is the only variable you are really trading.

The outlet field, read literally

• The outlet field on this sheet reads 1 Manway / Lid. That names an opening and not a discharge, and we print the field as written rather than converting it into a pipe size. No outlet dimension, no thread, no bulkhead and no valve is published, so none of them is claimed here. Tell us the line size you need to land, the valve type and the product, and we will confirm what 5180000N40 carries before you order.
• The drain path in practice: the outlet is the lowest point of the vessel and everything at the bottom carries the column above it, up to 51,291 pounds at the rating. Support the valve, any reducer and the first pipe run on steelwork off the stand and never on the tank, and put a flexible connector at the first joint so pump vibration stops there.
• Getting the last of it out: on this shape the liquid keeps running toward one point rather than spreading across a floor, so the end of a batch arrives quickly at the outlet. Keep the suction run short and straight off the cone and size the pump to the line rather than to the tank, or the vessel spends the last minutes of every batch fighting its own plumbing.
• Cone angle: no cone angle field is published on this sheet and the name carries none, so none is stated. Ask us to check the part number if the angle matters to your product.
• Access on top: an 18 inch threaded vented manway, 197 inches up plus the stand, with the vent arriving as part of the manway rather than as a separate line. Keep it clear and never blank, tape or wrap it to control an odour; a tank being pumped out that cannot take air in takes the load in its wall instead.
• Not published on this sheet and therefore not claimed: the inlet, the lid size, any lug or flange count, the warranty term and the NMFC number. Published: a specific gravity of 1.5, 34,194 pounds of water at 4,100 gallons, 51,291 pounds of max contents and a limit of 100 F / 37 C.

Where the tank stands over ground, a floor or a drain that would have to be recovered after a release, containment is a separate question from the tank and deserves a separate answer: the Captor containment comparison sets the contained polyethylene route against the alternatives. And on a 197 inch column a translucent wall gives you a daylight reading and nothing more, so work the instrumentation through the level gauge selection guide for chemical service before the tank is set.

Process water, blends and anything no heavier than water

This is the working tank rather than the special one. Treated and process water that has to leave nothing behind, wash and rinse water between product changes, make-up batches of polymer or coagulant at a water or wastewater works, liquid feed and crop input blending at agricultural retail, holding volume between two stages of a plant that run at different speeds, and food and beverage duty where the vessel is washed down between products. What they share is a liquid no denser than water and a hard requirement to empty completely, which is exactly the pairing this listing is built around: 51,291 pounds of allowed contents over 34,194 pounds of water, and a cone that takes the vessel to empty at the end of every run. The translucent white wall is the second reason to choose this part number over its black twin, and it is a practical one on a tank that is filled and drawn several times a week; being able to see the level from the walkway in daylight is worth more than it sounds. Two limitations, both honest. Daylight passes through the wall, so water-based product standing outside in a translucent tank becomes a seasonal cleaning job, and the black listing on this sheet exists for that reason. And the published service limit is 100 F / 37 C, which is lower than many Snyder vertical sheets carry, so a warm fill belongs in the conversation before the order rather than after it. Give us the liquid, its weight per gallon and its temperature and we will work the wall, the gasket and the fittings from there. Before any of that, look the liquid up in our chemical compatibility database and bring us what it says.

The lightest tank in this family, and the largest ticket it travels on

Lincoln, Nebraska is the moulding plant and the sheet gives Nebraska as the shipping state, so the lane price is mostly a function of distance from the middle of the country. The class reads 300 beside an LTL ship mode and no NMFC number is published. At 1,000 pounds in a 90 by 90 by 197 inch envelope this is the lightest tank on its own sheet and it still takes as much trailer as its heavier siblings, which is the clearest illustration you will get of why hollow moulded goods are quoted on space rather than on weight. Get the lane figure for your ZIP from the freight cost estimator; the listed price is before freight. It ships lying down and is stood up at your end. This sheet publishes no lifting lugs and no tiedown lugs, so plan the lift under the body rather than off any fitting, never off the manway, and agree the method with us before the truck is booked. No crane, rigging, permit or escort detail is published either, so none is described here. Set, level and anchor the stand before delivery, because a cone bottom tank with nowhere to stand is a tank lying in your yard. A light empty shell is easy to move and easy to lose control of: restrain it the moment it is upright, because 197 inches of empty tank catches wind that feels like nothing at ground level. Then fill it with clean water before product, hold the 34,194 pound load, and read the manway seal, the cone joint, the stand feet and the pad edge in that order before anything else happens on that pad. One job belongs before start-up rather than after it, which is getting the tank and its lines marked: our tank label and signage guide for bulk polyethylene storage sets out how that is done properly. Write the fill date on the manway with a paint marker; it answers the first question anyone asks about a tank.
