The same six thousand gallon envelope, rated one and a half
Part number SII-5280200N43 is a 6000 gallon cone bottom tank listed at 142 inches long, 142 inches wide and 136 inches tall, diameter 142 inches, at 1100 pounds empty and 1100 pounds shipping. The material field on this record reads Polyethylene and the colour field reads White. The wall carries a specific gravity rating of 1.5, and the sheet gives 75,060 pounds of max contents against 50,040 pounds of water at 8.34 pounds per gallon. The opening on top is an 18 inch threaded vented manway and the lid field reads 18 inches. The service limit is 100 F / 37 C. Plastic and 30 Degree are words in the listing name; the sheet publishes no cone angle field, and this page says the name carries the angle and leaves it there. Freight class reads 500 beside an oversize ship mode, and the tank is moulded at Lincoln, Nebraska. The outlet field and the inlet field are both empty. No warranty term, no NMFC number, no structural detail and no stand is published on this record, and none is claimed on this page.

Bulk holding at six thousand gallons, drawn down to nothing between runs
The duty is what puts a cone under a tank this large. Nobody pays for a sloped bottom on 6000 gallons unless emptying the vessel completely is part of the job, so the buyers are the operations that change product, settle solids, or account for every gallon at the end of a run. Bulk liquid held at a plant and pulled off by pump through a week. Make-up solution prepared in volume for a dosing system. Agricultural and horticultural blends that turn over between applications. Suspensions and slurries where anything heavy has to keep sliding toward one point instead of laying down a bed. Process water and recovery volumes that cycle daily. In all of them the value of the shape shows up at the end of the run rather than during it: on 50,040 pounds of water, whatever a flat floor would leave behind is a real volume that somebody has to pump, dispose of, or explain in the next batch record. The rating is the second half of the duty question and this listing is specific about it. The wall on this record is rated to a specific gravity of 1.5, and the sheet pairs that with 75,060 pounds of max contents. That is the honest ceiling for how dense a liquid the wall is rated to hold, and it is the number to check your product against before anything else on the page. It is also the field that separates this listing from others on the same envelope, so take the rating from the part number you are actually buying rather than from a family photograph. Then the building. The tank is 142 inches across, eleven feet ten inches, and 136 inches tall, eleven feet four inches, before the support is added. It is a wide vessel and it wants an open pad, a tank farm bay, or a high-bay building. It 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 this page prints none. The structure has to carry 1100 pounds of empty tank, 50,040 pounds of water and 75,060 pounds at the rating, landing on a handful of feet inside a 142 inch circle. Get that engineered and installed before the tank arrives, stack the finished height including the clearance above an 18 inch manway, and measure to the lowest fixed obstruction rather than to the roof. Size the volume with the tank sizing calculator and take the freeboard discipline from the tank sizing guide before the support drawing is fixed, because freeboard changes the height and the height changes the structure.
One envelope, several part numbers, and the taller ninety inch pair
| Part | Gallons | Length x width x height | Empty weight |
|---|---|---|---|
| SII-5280200N43 (this tank, white, rated 1.5) | 6000 | 142 x 142 x 136 in | 1100 lb |
| 5280200N40 (same envelope, same listed weight) | 6000 | 142 x 142 x 136 in | 1100 lb |
| 5280200N46 (same envelope, same listed weight) | 6000 | 142 x 142 x 136 in | 1100 lb |
| 5280200N42 (same envelope, heavier listing) | 6000 | 142 x 142 x 136 in | 1250 lb |
| 7040000N40 (less volume, a tall narrow column) | 5500 | 90 x 90 x 241 in | 1500 lb |
| 7180000N40 (more volume, the tallest here) | 6500 | 90 x 90 x 273 in | 2100 lb |
Four part numbers carry 6000 gallons in exactly the same 142 by 142 by 136 inch envelope, and three of them are listed at 1100 pounds while 5280200N42 is listed at 1250. That is the whole of the published difference between them on this record. No wall thickness, no layer count and no construction detail is given behind those weights, so none is described here. What this page does stand behind is its own sheet: material field Polyethylene, colour White, a specific gravity rating of 1.5, max contents 75,060 pounds and a service limit of 100 F / 37 C. If a different rating or a different colour in this envelope is what the specification needs, send us the part number and we will confirm what that record carries in writing before an order goes in; a family table is the wrong place to guess. The two ninety inch rows are a different building altogether and they are worth reading before the footprint is fixed. 7040000N40 holds 5500 gallons on a 90 inch circle at 241 inches, and 7180000N40 holds 6500 gallons on the same circle at 273 inches. Both take roughly half the floor diameter of this tank and pay for it in height, which is the right trade in a bay with vertical room and no spare slab, and the wrong one under a low roof or on a pad with a crane rail over it. Read the three together and the choice is a building question rather than a tank question: this listing is the one that spends floor and saves ceiling, and at 136 inches it is the shortest of the three by several feet.

Where the liquid leaves, and the outlet field that is simply blank
- The discharge: on this shape the lowest point of the vessel is a single spot and the contents keep running to it, which is why a cone is specified for anything that settles or has to be emptied between batches rather than drawn down and topped up.
- The blank field: the outlet entry on this record is empty. No outlet dimension, no thread, no bulkhead and no valve is published, so none is stated. Send us the line size you need to land, the valve type and the product, and we will confirm what this part number carries before an order is placed.
- The angle: the listing name reads 30 Degree. The sheet itself carries no cone angle field, and that is exactly how this page puts it. Ask before ordering if the slide of your product is what the purchase turns on.
- Supporting the pipework: valve, reducer and the first run of pipe go on their own steelwork off the support structure rather than on the tank, with a flexible connector at the first joint. Eleven feet four inches of full column puts real static head on that joint and a pump adds vibration to it.
- The opening on top: an 18 inch threaded vented manway, with the lid field also reading 18 inches. At 136 inches plus the support it is above head height everywhere, so plan the platform, the ladder and the fall protection in the same drawing as the structure, and bring the fill to a coupling at working level.
- The vent: supplied with the manway on this sheet rather than specified separately. On a tank being pumped down the air path is the wall's protection. Keep it clear, check it whenever the tank is opened, and never blank or tape it to control a smell.
- Ratings and blanks: a specific gravity rating of 1.5, 50,040 pounds of water at 6000 gallons, 75,060 pounds of max contents and a service limit of 100 F / 37 C. No inlet, no warranty term, no NMFC number and no structural detail appears on this record.
Plan the top of a tank this size before it is standing rather than after the first fill. Everything wants to go through the one opening, and the argument about where the fill, the vent and the level instrument live is much cheaper on paper.
The jobs that fill a tank this size, and the limits printed on it
Six thousand gallons is a plant volume rather than a yard volume. It turns up where a truck delivery has to land in one vessel, where a dosing or blending system draws continuously and cannot be allowed to run dry, and where a process holds product between two stages that run at different rates. Treatment works and municipal plants. Agricultural retail and custom application yards. Manufacturing and process buildings batching to a recipe. Mining, aggregate and industrial sites holding process water. Wash and recovery systems that cycle a large volume every day. In every one of them the reason for the cone is the same: what goes in has to come back out, and the accounting at the end of the run has to be honest. Two limits are printed on this record and both deserve to be read before an order. The service limit is 100 F / 37 C, which is a real constraint on a process that runs warm or on an outdoor tank in full sun, and it is the number to check your duty against rather than a figure taken from a similar listing. The specific gravity rating is 1.5, which describes how dense a liquid the wall is rated to hold and describes nothing else. It is not a statement about how your product behaves against polyethylene, and we will not present it as one. Name the liquid, the concentration and the year-round temperature when you enquire, look it up in our chemical compatibility reference before the gaskets, seals and valve are specified, and let the chemistry decide those. Beyond that the routine on a tank this size is about discipline rather than equipment. Confirm every support foot is bearing before the first fill and again after it. Walk the full circle at every inspection instead of reading the side you happen to park beside. Read the manway seal and the cone joint in daylight. Keep the vent on the same inspection round as the seal. And keep a written record of what the vessel has held, because on a tank that changes product the history answers questions that no single inspection can.

Eleven hundred pounds, class five hundred, Nebraska
Lincoln, Nebraska is the plant on this record and Nebraska is the shipping state, so the central plains are the short lane and either coast is a planned one. The freight class field reads 500, a numeric class rather than a mode, the ship mode reads oversize, and no NMFC number is published. The package is 142 inches by 142 inches by 136 inches at 1100 pounds: a very large shipment at a light weight, which is the normal shape of a hollow moulded vessel and the reason the class sits where it does. Price your own ZIP with the freight cost estimator; the listed price is before freight. It travels lying down and it is stood up at your end, so nominate the machine and the person for that operation before the truck is booked rather than working it out on the tail lift. This sheet publishes no crane, no rigging, no permit and no escort detail, so none is stated here; settle the offload equipment and the delivery window with us in advance. Set, level and anchor the support first. Sling under the body rather than by the manway, keep the tank restrained from the moment it is upright, and treat an empty vessel nearly twelve feet across as a sail, because that is how it behaves in a yard breeze. Fill with clean water before product, hold the 50,040 pound load, and read the manway seal, the cone joint, the support feet and the ground around the pad in that order, in daylight. Leave it standing full overnight and look again in the morning, because what moves overnight is almost never the tank. Check the label against the part number you ordered before anything is uncrated; the listings in this envelope are told apart by their numbers rather than by their photographs. Write the fill date on the manway with a paint marker; it answers the first question anyone asks about a tank.
