Norwesco 6500 Gallon Vertical Liquid Storage Tank

Two plants, one oversize class, and 6500 gallons between them

The origin network on this part number is two plants: St. Bonifacius, Minnesota, and Hanford, California, with a ships-from field naming Minnesota and California. That is a deliberate pair rather than a thin one; it puts a plant at each end of the country and leaves the middle to be argued over at quote time. If you are buying east of the Mississippi it is worth asking which plant is serving the order before you build the freight into a budget, because on an oversize load the answer moves the number more than anything else on this page does.

Freight class and ship mode both read OVS and no NMFC code is published beside them. A 119 inch body standing 150 inches is twelve feet six inches of tank on a nearly ten foot circle, which is flatbed freight with a scheduled window and machinery waiting. The practical consequence is the same every time and it is still the thing that goes wrong most: the tank has to travel from the trailer to its final position in one movement, so decide the path, the turning room and the lift before you place the order rather than on the morning of the delivery. Settle the working volume with our tank sizing calculator and check it against your cycle with the tank sizing guide.

Four 6500 gallon rows in one shell, separated by weight and colour words

Four rows share the 119 by 119 by 150 inch envelope and the sheet separates them by weight and by colour word: 1346 lb, 1440 lb here, and two rows at 1506 lb apiece. Two records carrying an identical 1506 lb figure with different colour words is exactly the kind of thing worth checking against the plant before you order, and we print it as found rather than picking one. The interesting outlier is 47620B. It holds 6502 gallons, a hair more than this tank, in a 102 inch body standing 196 inches, at 1700 lb. Same volume, completely different building: sixteen feet four inches of height in exchange for a 102 inch footprint instead of a 119 inch one. This record is the wide-and-lower option at the same capacity, and that is the reason to take it: twelve feet six inches clears a great many roofs that sixteen feet four inches does not. One thing to note for the record: the colour field on this sheet reads blue, while a buyers guide we carry for the same capacity and envelope describes it as natural white. We cite the field on the record and flag the difference rather than quietly choosing.

The access opening, then the outlet, then the temperature ceiling

• Access is a 16 inch threaded vented manway, matched by a lid size field that also reads 16 inches. One opening, agreed by two fields, which is a cleaner specification than several records in this family carry.
• The vent is built into the manway description rather than provided separately, so the lid is a working component: it stays clear, and nothing gets wrapped, taped or stacked over it.
• The outlet is a 3 inch PP female NPT bulkhead fitting with a 2 inch reducer. A 2 inch line connects without an extra part and the 3 inch body is there if the flow requirement grows later.
• There is no inlet field on this sheet. Nothing is described, so nothing is claimed.
• The service ceiling is 120 F / 48 C.
• Specific gravity is 1.9, expanded as a maximum of 15.87 pounds per gallon, with a maximum contents figure of 102999 lb against 54210 lb of water.
• The warranty field reads a 3 year limited term with full replacement, cited to the maker's 2024 liquid storage catalog.

102999 lb is the largest maximum contents figure on any 6500 gallon row in this family and it is the number that ought to drive the conversation with whoever is designing the support. The honest limitation is the usual one for a wide vertical: a 16 inch manway at the centre of a 119 inch top does not give you access to the wall, so plan cleaning and inspection around equipment rather than around reach. As an install specific, the 2 inch reducer on the outlet is a threaded assembly rather than a moulded feature, and it should be checked for tightness after the first fill and after the first cold snap.

102999 lb of maximum contents at a 1.9 figure

This is a tank bought for density as much as for volume. 54210 lb of water against a 102999 lb maximum contents figure describes a shell built for contents well heavier than water, and that is the specification to check your liquid against before anything else on this page. Volume second: 6500 gallons at twelve feet six inches on a nearly ten foot circle is a shape that fits inside a great many industrial bays where a taller tank of the same capacity would not.

Two pieces of reading earn their place here. Concrete pad sizing for above-ground polyethylene tanks is the piece to read first, because a wide footprint carrying a six-figure contents weight is a support problem before it is a storage problem. Fire water reservoir design for rural and remote sites covers the held-volume and cold-weather side if this tank is being bought as reserve rather than as process storage. And our 6500 gallon vertical buyers guide walks the whole size class, including the rows in the table above.

Crated 150 by 119 by 119, and the receiving check that fits this shape

The crate is given as 150 inches long by 119 by 119, which is the tank laid over, and the weight on the bill is 1440 lb, the same as the empty weight. Class and mode read OVS, there is no NMFC code, and the plant is either St. Bonifacius or Hanford.

Because this tank arrives on its side on a flatbed, the check that pays for itself is a rotation check: with the tank still strapped, note where the manway is pointing, and then note it again after the tank has been stood up. A shell that has rotated inside its blocking during transit has been rubbing against something for the whole trip, and the mark it leaves is on the side that was down, which is the side nobody looks at once it is vertical. Get a real freight figure for your ZIP from the freight cost estimator; the listed price is before freight. Fill it with water and leave it standing for a day before you put anything else in it, because a wide tank settles its pad in the first twenty-four hours and you want that to happen with water in it rather than with your product. Keep one spare gasket for the outlet fitting on the shelf; it is the part that fails on a holiday.
