3000 Gallon 30 Degree HDPE Cone Bottom Tank in White

The heavy row of the three thousand family, against the lighter listings

The family is one 3,000 gallon shell, 90 inches across and 144 inches tall, listed several ways, and the sheet separates the rows by empty weight and by the rating that goes with it. This is the 670 pound row at a specific gravity rating of 1.9. It allows 47,538 pounds of contents where the same 3,000 gallons of water weighs 25,020 pounds at 8.34 pounds per gallon, and that is the largest allowance on any tank in this group. It is also the only reason to choose this row. If your product is water, treated water or anything at or under the weight of water, the 500 pound listings on this same shell hold the same 3,000 gallons and the difference stays in your pocket; the sheet offers no other distinction between them and this page will not invent one. If your product is genuinely dense, this row is what lets the vessel be filled as the volume it is rather than to a line somebody has to remember. Work out the weight per gallon first; it decides this page. The colour field reads White, which puts a rough level in an operator's eye from the floor in daylight and lets light reach the contents, so on anything that should be kept dark the darker listings are the better answer. Then the part that carries all of it. A cone bottom tank 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 support is a separate item with its own drawing and its own lead time, and no stand height, rated load or material is stated here. On this listing it has more to answer than anywhere else in the family: 670 pounds of empty tank, 25,020 pounds of water and up to 47,538 pounds at the rating, landing on a few feet inside a 90 inch circle with 144 inches of shell standing above them. That is twelve feet of tank before the stand is added, so the roof line, the door and the route in all want measuring before a part number is fixed rather than after. Size the volume with the tank sizing calculator, take the freeboard from the tank sizing guide, and leave real clearance under the cone for whatever the discharge has to feed.

Three listings at three thousand gallons, a smaller one below and a wider one above

The top four rows are one shell listed four times at 3,000 gallons, 90 inches across and 144 inches tall, at 670 pounds on two rows and 500 pounds on the other two. The shape never moves; the weight and the rating do. The last two rows are the ones to study, because they move in different directions. The 2,600 gallon listing stands at 139 inches on the same 90 inch circle, so stepping down to it buys almost no headroom back and gives up real volume, which makes it the wrong saving in most buildings. The 3,600 gallon listing is the genuinely different tank in this table: 102 inches across and only 125 inches tall, at 1,090 pounds. It is wider and considerably shorter, which is the trade a low roof forces, and it weighs far more than anything else here, so the lift, the ground and the freight all change with it. Read the table as two questions rather than one. First, is your building height-limited or floor-limited, because that picks the circle. Second, what does your liquid weigh per gallon, because that picks the row. Get those the right way round and the part number falls out of the two answers. For the long read on a cone bottom tank at this capacity, our complete buyer's guide to a three thousand gallon cone bottom tank with a shallower bottom walks the whole selection rather than one part number, and the cone angle selection guide is the one to read if the bottom angle rather than the volume is still open.

One eighteen inch opening at the top of a very tall column

• The vent comes with the lid on this sheet: an 18 inch threaded vented manway, with the lid size field also reading 18 inches, and no separately specified vent. On a dense liquid being pumped out of a tall shell that air path is doing real structural work, so keep it clear, look at it every time the tank is opened, and never blank, wrap or tape it.
• Getting to it is the planning job on this tank: the lid sits at the top of 144 inches of shell plus whatever stand carries it, and this sheet counts no ladder lugs and no structural attachments at all. The ladder or platform belongs to the structure, and the fill line belongs at a coupling at working level rather than in anyone's hands at the top.
• The outlet: this sheet publishes no outlet field and no inlet field, so no discharge size, thread, bulkhead or valve is stated or implied. 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.
• Under the cone: 30 Degree is the maker's name word and the sheet carries no cone angle field, so nothing measured is claimed. What is certain is the load. Everything hung at the low point holds up the column above it, and here the sheet allows that column to reach 47,538 pounds, so carry the valve, any reducer and the first run of pipe on steelwork off the stand and never on the tank, with a flexible connector at the first joint.
• Not on this sheet: a service temperature limit, a warranty term, an NMFC number, a lug count, a flange count and any stand detail. Nothing is claimed for them. Published: a rating of 1.9, 25,020 pounds of water at 3,000 gallons and 47,538 pounds of max contents.
• Level: a translucent wall gives a rough reading by eye in daylight and nothing you would meter from. On the largest and heaviest fill in this family, specify the level instrument with the tank rather than after it.

Because no service temperature figure is published on this sheet, treat a warm or heated fill as a question for us rather than an assumption to carry into the installation.

Bulk holding where the product weighs more than water

Three thousand gallons at a 1.9 rating is bought by operations that take dense product in bulk and want the vessel used as the volume it is. Concentrated mineral and salt solutions in a process building, brines and spent liquor in a metals plant, treatment chemistry held at working strength, liquid fertiliser and crop input concentrate at an agricultural retailer taking full loads in season, and heavy process intermediates that sit between two stages running at different rates. Against 25,020 pounds of water in the same 3,000 gallons, the 47,538 pound allowance is what turns those loads from marginal into routine. The cone is the second argument and at this weight it is the stronger one, because dense product left standing in the last inches of a flat floor is heavier, usually worth more and considerably harder to dispose of than a light one; the vessel giving all of itself back at the changeover is worth more per gallon of residue avoided as the product gets heavier. The third consideration is the ground, and on this listing it is not a footnote. The heaviest rated fill in this family lands on a small number of stand feet inside a 90 inch circle, so the pad, the support and the anchors deserve exactly as much attention as the tank, and the first full product fill wants watching from the start. Two honest limits: no service temperature figure is published on this sheet, and twelve feet of dense liquid on a narrow circle stratifies more readily than a wide shallow vessel would, so plan the draw point and any mixing with the tank. Check the product in our chemical compatibility reference and send us its specific gravity with the enquiry.

Six hundred and seventy pounds and a twelve foot package

Lincoln, Nebraska is where this one is moulded and Nebraska is the origin state on the sheet, so the plains and the Midwest are the short lanes and both coasts are the long ones. The freight class reads 500 beside an OVS ship mode and no NMFC number is published. The package measures 90 inches by 90 inches by 144 inches at 670 pounds, which is twelve feet of envelope around a very light load, and it is the length rather than the weight that writes the ticket. Price your own lane with the freight cost estimator before the order goes in; the listed price is before freight. It travels lying down and is stood up at your end, and at twelve feet that upending is the longest in this group: agree the machine, the ground and the person for it in advance rather than working it out at the tailgate. The sheet publishes no crane, no rigging, no permit and no escort detail, and none is described here; settle the offload equipment and the delivery window with us before the truck is booked. Have the support set, levelled and anchored first, because a tank with no flat bottom has nowhere to wait while concrete cures. No lifting lugs are counted on this sheet, so sling under the body rather than off the manway, and restrain the shell the moment it is upright. Commission with clean water rather than product: hold the 25,020 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. Measure the height to the lid and to the discharge with the tank standing and write both on the site plan, because on a twelve foot shell every later job is quoted off those two numbers and nobody will want to climb up for them twice. Photograph the outlet fitting from below before the pipe goes on; a slow weep is easier to compare against than to describe.
