4100 Gallon 45 Degree Plastic Cone Bottom Tank

A steeper cone spends height and buys drainage

Where this tank sits is decided by one number more than any other, and it is 198 inches. That is the shell alone, sixteen and a half feet of it, before anything is put underneath. A cone bottom tank has no flat floor and cannot stand on its own bottom, so a stand goes under it, and a steeper cone needs a taller stand to give the same working clearance below the discharge as a shallower one. This sheet publishes no stand, no legs, no skirt, no support ring and no bolt pattern, so no stand height, rated load, leg count or material appears on this page and the support is bought as a separate item on its own drawing. What the sheet does publish is the loading that support has to answer: 1,399 pounds of empty tank, 34,194 pounds when it is full of water, and up to 64,969 pounds of contents at the rating, gathered onto a few feet inside a 90 inch circle instead of spread across a floor. Hand those three figures to whoever specifies the pad, because a slab poured for a weight and not for point loads is the one that cracks. Now do the height sum properly, since this is the listing where it bites. Shell plus stand plus pad, measured against the lowest thing above the tank position, which in most buildings is a duct, a sprinkler drop or a crane rail rather than the roof. A steeper angle is a genuine trade: you get better drainage and you pay for it in floor-to-outlet height, and the payment is not negotiable after the concrete is poured. If the building cannot take it, the answer is a shallower cone or a wider shell, not a shorter stand that leaves no room for the valve. Outdoors, check the ground rather than the roof. Eighteen feet of tank and stand together is a sail as well as a vessel, and the pad, the anchors and the drainage around it all deserve attention before the tank arrives rather than after the first storm. Size the volume with the tank sizing calculator, take the freeboard discipline from the tank sizing guide, and read the cone angle selection guide before you commit to the steeper geometry, because it is the cheapest hour you will spend on this purchase.

The forty-one hundred group and the sizes on either side of it

Everything in this table stands on a 90 inch circle, which is the single most useful fact in it. Move up or down this ladder and the pad drawing, the bund and the aisle do not change; only the height and the gallons do. The top four rows are the 4,100 gallon group, and they are separated on the sheet by empty weight rather than by anything the sheet explains: 1,399 pounds here, 1,000 pounds on two rows, 1,500 pounds on the heavy duty row. What you actually buy against is the rating, and this row publishes 1.9 with 64,969 pounds of max contents, which is the row for product meaningfully heavier than water. If your liquid is no heavier than water, read a lighter row instead rather than running this one part full. The bottom two rows are the ladder. The 3,900 gallon row at 180 inches hands back a foot and a half of height for a few hundred gallons, which is a good trade in a tight building. The 4,400 gallon row at 200 inches costs almost nothing in height and adds useful volume, which is the trade to consider if there is any chance the duty grows. Measure the headroom once and keep the option open in both directions; it is far cheaper to decide this now than to discover it when a second tank is needed. Where the angle rather than the capacity is the open question, the cone angle selection guide sets the common angles against each other properly.

Still deciding between these? Freight to your ZIP often settles it; the wider tanks ship differently. Or call 866-418-1777 and we will walk the table with you.

No outlet on the sheet, and what that means for the valve you hang

• The outlet: this sheet publishes none, and the inlet field is empty as well. No discharge size, thread, bulkhead, drain or valve is stated or claimed here. Tell us the line size you need to land, the valve type and the liquid, and we will confirm what this part number carries before anything is ordered.
• The load under the cone: the sheet allows 64,969 pounds of contents above whatever you fit at the low point, which is the heaviest allowance in this batch. Carry the valve, any reducer and the first pipe run on steelwork off the stand rather than on the tank, with a flexible connector at the first joint so pump vibration stops before the cone.
• The steeper angle at the bottom: 45 degrees is the maker's name word for this listing and the cone degrees field is empty. A steeper wall is the reason people buy this shape for product that hangs about, and it is also the reason the discharge sits higher off the floor. Leave real room underneath for the valve and for a person to work on it.
• The manway: 18 inches, threaded and vented, with the lid size field reading 18 inches. The vent arrives with the manway, and it is what keeps the wall out of trouble while a pump draws the tank down. Keep it clear, check it whenever the tank is opened, and never blank, wrap or tape it.
• Access: the manway is at the top of 198 inches of shell plus the stand, and no ladder lugs or structural attachments are counted on this sheet, so plan the ladder or platform with the structure. The fill line belongs at a coupling at working level rather than in somebody's hands at the top.
• Published limits: a specific gravity rating of 1.9, 34,194 pounds of water at 4,100 gallons and 64,969 pounds of max contents. No max operating temperature and no warranty term is published on this sheet, and neither is claimed here.

Where so little hardware is dimensioned, the fitting schedule is settled in conversation before the order rather than read off a page afterwards.

Dense product that has to clear the bottom every batch

Two things on this sheet point at the same buyer: a 1.9 rating with 64,969 pounds of max contents, and the steeper of the common cone angles. Put together they describe product that is heavier than water and reluctant to move. Concentrated mineral and salt solutions in a process building, liquid fertiliser and crop protection concentrates at an agricultural retailer, treatment chemistry held at working strength, brines, spent liquor and pickling solution in a metals plant, slurries and suspensions that carry solids and still have to leave the vessel clean, and heavy recovered streams held before they are processed or collected. Dense product left in the bottom of a flat floored tank is heavier, more valuable and more of a disposal problem than a light one, which is why the full-drain geometry pays back faster at high specific gravity than at low, and why the steeper angle is worth its height to the people who need it. Two cautions belong here. The sheet publishes no temperature limit, so a hot fill is a conversation rather than an assumption. And a tall column of dense liquid puts real load into everything below it, so the stand, the pad and the anchors are not the place to save money on this listing. Bring us the liquid, its weight per gallon and its temperature at fill, and check it first in our chemical compatibility reference, because the wall, the gasket and the trim get decided in that order.

Fourteen hundred pounds before a drop of liquid goes in

This one is moulded at Lincoln, Nebraska, and Nebraska is the origin state on the sheet, so the plains and the Midwest sit on the short lane and both coasts on the long one. The freight class reads 500 beside an oversize ship mode, and no NMFC number is published. The shipping size is listed at 90 by 198 by 198 inches, which is the tank lying down, at 1,399 pounds; that is the heaviest empty tank in this batch and still a load that prices on space rather than on the scale. Price the lane to your own ZIP with the freight cost estimator; the listed price is before freight. It travels on its side and is stood up at your end, and at this height standing it up wants clear air above the trailer, a wide turning area on the ground and somebody nominated for the job before the truck arrives. The sheet publishes no crane, no rigging, no permit and no escort detail, so none is described here; agree the offload equipment and the window with us before anything is booked. Have the stand set, levelled and anchored first. No lifting lugs are counted on this sheet, so sling under the body rather than off the manway, and keep the shell restrained from the moment it is vertical. Commission with clean water rather than product: hold the 34,194 pound water load, walk the manway seal, the cone joint, the stand feet and the pad edge in that order, and leave it standing full overnight. Because this listing will hold something heavier than water, watch the stand feet again on the first full product fill, since that is the load the structure has never seen before, and write the date of that fill on the site paperwork so every later inspection has something to read against. Write the outlet fitting size and material on the site plan; the replacement is ordered by those two words.
