3900 Gallon 30 Degree Plastic Cone Bottom Tank in White

Headroom first, because nothing about the height is adjustable later

Measure the room before you read another line of the specification. This shell is listed at 179.75 inches, a shade under fifteen feet, and that is the tank alone. A cone bottom tank has no flat floor and cannot rest on its own bottom, so a stand goes underneath it, and the stand is tall on purpose because clearance below the discharge is the whole reason the shape exists. This sheet publishes no stand, no legs, no skirt, no support ring and no bolt pattern, so no stand height, load, leg count or material is stated on this page; the support is a separate item. The sum you have to do is still the same one: shell plus stand plus pad, measured against the lowest obstruction over the tank position, which is nearly always a duct, a sprinkler drop, a light fitting or a crane rail rather than the roof steel. Get that wrong and there is no adjustment available afterwards, because a tank cannot be shortened and a building is expensive to raise. Then look down. The loading this structure has to carry is published: 900 pounds of empty tank, 32,526 pounds of water and up to 48,789 pounds of contents at the rating on this sheet, arriving through a few stand feet inside a 90 inch circle rather than spread across the floor. Point loads are what crack a pad specified only for weight, so give the figures to whoever pours it. Keep the pad edge visible, leave working room on every side rather than pushing the tank into a corner, and decide where a spill would run before there is one to think about. The last piece of siting on this particular listing is temperature. It is one of the few rows here that publishes a limit, 100 F / 37 C, and that figure stops being theoretical in a hot fill or on a shell standing in full southern sun, so a shaded position is worth something real. Fix the volume with the tank sizing calculator, take the freeboard from the tank sizing guide, and where the cone angle is the open question, the cone angle selection guide compares the common angles honestly.

Reading the thirty-nine hundred rows by weight rather than by name

Read this table by the weight column and it makes sense quickly. Four rows hold 3,900 gallons on the same 90 inch circle, and the sheet separates them by empty weight: 900 pounds on this listing, 1,100 pounds on two others, 1,400 pounds on the heavy duty row. The sheet explains that spread nowhere, so this page explains it nowhere either. What it does publish per row is the rating, and that is what a buyer should be matching. This one is the 1.5 row with 48,789 pounds of max contents, which covers water, treated water and the broad run of process liquid no heavier than water, and that is the majority of real cone bottom duty. Buying above your own duty buys paperwork rather than capability; buying below it is not a saving at all. Get your liquid's weight per gallon written down before the part number is chosen and this decision takes about a minute. The last two rows change the building rather than the liquid. The 3,600 gallon row sits on a 102 inch circle at 125 inches, wider and a great deal shorter, which is the answer when the ceiling is fixed and the floor is not. The 4,100 gallon row sits on this same 90 inch circle at 197 inches, more volume bought purely with height and no change to the pad drawing. Where the circle holds, a size change is cheap; where the circle moves, the pad, the stand and the bund move with it. If the stand is what you are really deciding, the buyer's guide to a three hundred gallon cone bottom tank with a poly stand works through the support question in the detail it deserves.

The blank drain end, the vented manway, and the warranty beside them

• The drain end: this sheet publishes nothing there. Both the outlet field and the inlet field are empty, so no discharge dimension, thread, bulkhead, drain or valve is claimed on this page. Give us the line size you need to land, the valve type and the product, and we will confirm what this part number carries before it is ordered.
• Supporting what you do fit: everything hung at the low point holds up the column above it, and the sheet allows that column to reach 48,789 pounds. Take the weight of the valve, any reducer and the first pipe run on steelwork off the stand, never on the tank, with a flexible connector at the first joint.
• The manway: 18 inches, threaded and vented, with the lid size field reading 18 inches as well. The vent comes with the manway rather than as a separate specification, and it is the cheapest fitting on the vessel and the one whose failure costs the most. Keep it clear and never blank it.
• Working at the top: the manway sits above 179.75 inches of shell plus the stand. No ladder lugs and no structural attachments are counted on this sheet, so the access arrangement belongs to the structure rather than to the tank, and the fill should land at a coupling at working level.
• The angle: 30 degrees is the maker's name word for this listing and the cone degrees field is empty, so nothing is measured here. Ask us to confirm the geometry against the part number if drainage behaviour is what decides the purchase.
• Published limits: a specific gravity rating of 1.5, 32,526 pounds of water at 3,900 gallons, 48,789 pounds of max contents, a service limit of 100 F / 37 C and a 3 year warranty. That warranty and that limit are on this row and not on every row of the family, which is worth knowing when two part numbers look interchangeable.

A white wall gives an operator only a rough sense of level in daylight, so the level instrument belongs in the same order as the tank rather than in next year's budget.

Everyday process liquid at thirty-nine hundred gallons

This is the ordinary row of the family and the volume is what makes it useful. Thirty-nine hundred gallons takes a full bulk drop without splitting it between vessels, and the cone means the vessel gives all of it back at the end. Process and treated water holding that still has to drain fully, liquid fertiliser and crop input blending at an agricultural retailer, polymer and coagulant make-up at a water or wastewater works, batch preparation and intermediate holding in manufacturing, wash and rinse systems emptied between runs, and buffer volume between two stages that run at different rates. The rating is what makes it the ordinary row: 1.5 with 48,789 pounds of max contents covers water and the general run of process liquid, and if your product is genuinely denser there is a heavier row on this shell carrying its own figures. The service limit is the other thing to hold on to. This listing publishes 100 F / 37 C, and that is a real constraint on a hot wash, on a recovered stream that arrives warm and on a shell in direct sun through a southern summer. Plan the fill temperature rather than discovering it. The honest caution is shape rather than tank: a tall narrow column stratifies more readily than a wide shallow vessel, so if your blend separates, decide the draw point and the mixing arrangement when you decide the tank. Check the liquid in our chemical compatibility reference before the gaskets and valves are chosen, because the chemistry decides the trim and the vessel does not.

Nine hundred pounds, class 400, shipped lying down

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 lane and both coasts are the long one. The freight class reads 400 beside an oversize ship mode, and the sheet publishes no NMFC number. The shipping size is listed at 180 by 90 by 90 inches, which is the tank lying down, at 900 pounds; that is a very large envelope carrying very little weight, and it is the combination that surprises people when the quote lands. Run your own ZIP through the freight cost estimator before you commit; the listed price is before freight. It travels on its side and is stood up at your end, so agree who is doing that and with what before the truck is booked, and make sure there is clear air above the trailer as well as room beside it. 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 in advance. Set, level and anchor the stand before the trailer arrives, because there is nowhere sensible to park a cone bottom tank 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 as soon as it is vertical. Prove the installation with clean water before product: hold the 32,526 pound water load, read the manway seal, the cone joint, the stand feet and the ground around the pad in that order, and leave it standing full overnight. Then photograph the cone from below before any pipe goes on, because a slow weep is far easier to compare against a picture than to describe over a phone. Chalk the full-water line on the outside after the first fill; it is the level every later reading gets checked against.
