Snyder Industries 4400 Gallon XLPE Heavy Duty Cone Bottom Tank

The job this one gets bought for: dense batch, full drain, level you can see

Three things have to be true at once before this part number is the right answer, and the sheet supports all three. The product is heavier than water, so the 1.9 rating and 69,722 pounds of max contents are doing real work against a vessel that only holds 36,696 pounds of water. The vessel has to empty completely between batches, so the 30 degree cone earns its cost at the changeover rather than during the run. And somebody needs to see the level without walking up to an instrument, which is what the natural white wall buys you and what the black listing in the same family does not. That combination points at a specific kind of operation: agricultural retail blending concentrates to order, a treatment works making up 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. Size comes next. At 4,400 gallons this is the tank people move up to when 4,100 gallons stopped covering a delivery and down to when the next size up would have stood half full, and half a tank of dense product is a worse buy than the right tank. Then the ground. A cone has no flat floor, 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 separately, set before the tank arrives, and no height, rated load or material for one is stated here. The loads it has to take are 1,700 pounds of empty tank, 36,696 pounds of water and up to 69,722 pounds of rated contents, arriving at a few feet inside a 90 inch circle rather than spreading over a slab. Fix the volume with the tank sizing calculator, take the freeboard discipline from the tank sizing guide, and settle the support against the cone bottom tank stand compatibility matrix before you order either piece.

Four 4400s, a 4100 below and a wider 4600 beside

The first four rows are the same shell four times: 4,400 gallons, a 90 inch circle, 200 inches tall. The sheet separates them by empty weight, 1,700 pounds on this listing and on 5200000N48, 1,400 pounds on 5200000N46 and 5200000N49, and by the names it prints on each. It offers no account of the weight difference, so none is manufactured here; what it does publish for this listing is the 1.9 rating and 69,722 pounds of max contents, and that is the figure to hold your product against. If your liquid is no heavier than water, the 1,400 pound listings are the right column and this one is more tank than the job needs. The row that changes the question is 5180000N40 at 4,100 gallons in 197 inches on the same 90 inch circle: three inches shorter, three hundred gallons smaller, and a genuine alternative when the real batch is smaller than the round number in the specification. 8050100C75501 changes it the other way, holding 4,600 gallons at only 154 inches by opening out to a 102 inch circle, which is the move when the ceiling is fixed and the floor is not. Height against footprint decides more cone purchases than any rating does. Where the crosslinked wall is itself the question rather than the shape, our read on XLPE against HDPE for chemistry duty is the place to start.

Thirty degrees down to the outlet, and what the sheet names there

• The cone: published at 30 degrees on this sheet, the middle of the common angles. That keeps a free-flowing liquid moving toward one point and will hold on to material that packs or consolidates. If your product settles hard, say so when you enquire and let us talk geometry rather than gallons.
• The outlet field: it reads 1 Manway / Lid. That names an opening and not a discharge, and we print the field as it reads instead of turning it 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 5200000N42 carries before it is ordered.
• What hangs at the low point: everything at the bottom of a cone carries the column above it, up to 69,722 pounds on this listing. Support the valve, any reducer and the first pipe run on steelwork off the stand rather than on the tank, and use a flexible connector at the first joint so pump vibration stops there.
• Structure the sheet does dimension: 4 tiedown lugs, 8 lifting lugs, ladder lugs and 3 flange lines. The lifting lugs are the difference between a planned lift and an improvised one on the day, and the tiedown lugs are what the carrier will look for.
• Access on top: an 18 inch threaded vented manway at the top of 200 inches of shell plus the stand. The vent comes with the manway here rather than as a separate specification. Never blank or wrap it to control an odour; a tank being pumped out that cannot take air in takes the load in the wall instead.
• Not published, therefore not claimed: the inlet, the lid size, the warranty term and the NMFC number. Published: a specific gravity of 1.9, 36,696 pounds of water at 4,400 gallons, 69,722 pounds of max contents and a service limit of 100 F / 37 C.

Even with a translucent wall, a 200 inch column outdoors is not read by eye in every light, and dense product makes the reading matter more: the level gauge selection guide for chemical service compares radar, ultrasonic, hydrostatic and magnetostrictive for this exact kind of vessel. Where the tank stands over ground 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.

Concentrates, blends and anything heavier than water

The rating is the reason this listing exists, so the duty follows the rating. It is bought for liquids that weigh more per gallon than water: 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. In every one of those the arithmetic is the same. The vessel holds 36,696 pounds of water at 4,400 gallons and is rated to 69,722 pounds of contents, so a dense product can fill the tank instead of filling half of it. Work out the weight per gallon of what you are storing before you compare part numbers, because that single figure moves this decision further than price does. The natural white wall is the second reason people land here rather than on the black listing at the same weight: an operator can see where the liquid is from the walkway, which matters most on a vessel that is filled and drawn down several times a week. The 30 degree cone is the third, and it pays back fastest on exactly these products, because dense material left behind in a flat bottomed tank is heavier, more valuable and more expensive to dispose of than light material. One honest limitation: the sheet publishes 100 F / 37 C as the service limit, which is lower than many Snyder vertical sheets carry, so a hot fill or a summer pad in the south is a conversation to have before you order rather than after. Look your product up in our chemical compatibility database first, because on a dense liquid the gasket and the fitting material matter as much as the shell does.

Seventeen hundred pounds, eight lifting lugs, one Nebraska plant

This tank is moulded at Lincoln, Nebraska and the sheet gives Nebraska as the shipping state, which makes the Midwest the short lane and either coast the long one. The class reads 300 beside an LTL ship mode and no NMFC number is published. It moves at 90 by 90 by 200 inches and 1,700 pounds, so like every large moulded tank it costs what it costs because of the room it takes rather than the weight it puts on the trailer. Get the lane figure for your own ZIP from the freight cost estimator; the listed price is before freight. It arrives lying down and is stood up at your end, and this is one of the few sheets in the family that helps you with that: it lists 8 lifting lugs and 4 tiedown lugs, so the lift has published attachment points and the carrier has published restraint points. Use them, and never lift off the manway. No crane, rigging, permit or escort detail is published on this sheet, so none is described here; agree the offload equipment and the window with us before the truck is booked. Have the stand set, levelled and anchored first. Then commission with clean water rather than with product: take it to the 36,696 pound water 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 any dense liquid goes near it. The last job before handover is the cheapest one on the list, which is to label the vent from the ground so nobody caps it by mistake in six months. Write the outlet fitting size and material on the site plan; the replacement is ordered by those two words.
