Norwesco 3135 Gallon Horizontal Leg Tank in Black

Who fills 3135 gallons at 12.52 pounds a gallon

Start with the duty, because on a tank this size the duty is what picks the part number. The buyer for this record is someone moving or holding a liquid that is heavier than water and wants the number in writing before the first fill. The sheet gives it: a 1.5 rating, stated as a maximum of 12.52 pounds per gallon, and a maximum contents weight of 39219 lb across the full 3135 gallons. Water is the easy case at 26146 lb. Anything denser than water lives in the space between those two figures, and if your liquid sits above 12.52 pounds per gallon this is the wrong row on the sheet, not a tank to fill part way and hope.

The second thing that duty decides is the shape you are buying. A horizontal leg tank keeps its volume low and long instead of tall, which is why the body runs 150 inches down one axis and only 88 across. That matters when the liquid has to be pumped rather than poured, because the whole contents sit close to the height a pump wants to see, and it matters for a site where a tall body is out of the question. The ground under it decides the rest of the install: the moulded legs put the load down on a handful of small bearing areas rather than spreading it like a flat floor, so give the full 150 by 88 inches continuous, level, load-bearing support under every leg, not under most of them. Check it with a straightedge in two directions before anything is unstrapped. To turn a duty cycle into gallons before you get here, the tank sizing calculator does the arithmetic and the tank sizing guide walks through choosing a body shape once the number is settled.

Four 3135 gallon records, and the one you are on

Four rows in this table hold 3135 gallons and three of them are 1107 lb or 957 lb, so weight is where this family separates rather than volume. This record is the lightest of the four at 952 lb, and it is also the one whose height field reads 88 inches where the other three read 80. We print that as the sheet has it and do not reconcile it for you; if the exact standing height decides your building, ask us and we will get the figure confirmed in writing before you order. The two outliers are worth knowing about as well. 45362 gives up 3135 gallons for 2650 in a body only 122 inches long, which is the row for a site that runs out of length rather than money, and N-44597 buys 3250 gallons in a body of almost the same length at 152 inches. Neither is a substitute for this row; they are the neighbours on either side of it.

Pulling from a 3 inch bulkhead with a 2 inch reducer

• The draw-off is the reason this sheet reads the way it does. The outlet field is a 3 inch polypropylene female NPT bulkhead fitting fitted with a 2 inch reducer and a siphon tube, so the tank arrives set up to be pumped out rather than gravity-drained into a pail.
• Size the suction side to the reducer, not to the bulkhead. A pump hung on a 2 inch route wants 2 inch line, a 2 inch valve and the shortest, straightest run you can give it; putting a bigger pump on the other end of a smaller pipe only starves it.
• A siphon tube draws from inside the tank rather than off the shell wall, which is what lets a horizontal body be emptied further than its outlet height alone would suggest. Nothing on this record states a residual volume, so do not plan a process around the tank going completely dry.
• A bulkhead fitting is a sealed penetration through the wall. Hand-tight first, no wrench force levered against the shell, and every length of pipe downstream carried by its own support rather than by the fitting.
• Access overhead is a 16 inch threaded vented manway, and the lid size field agrees at 16 inches. It is vented on purpose: a tank that cannot breathe as a pump pulls it down is a tank that deforms, so that path never gets plugged.
• The service ceiling is 120 F / 48 C. It is a ceiling, not an operating target, and it is the only thermal figure on the sheet.

The honest limitation on this record is the inlet: there is no inlet field at all. Filling is through that 16 inch manway unless you specify something else, and on a body 88 inches tall that means planning the fill route and the safe access to it as part of the job rather than as an afterthought. The install specific worth carrying away is the valve: fit it close to the tank and put a union immediately downstream of it, so the line can be broken later without draining 3135 gallons to do it.

Where a 150 inch black leg tank earns its keep

What goes in a tank at this rating is usually something with a density worth checking and a blending habit worth understanding, which is why two pieces of our own writing belong beside this page rather than inside it. The first is the field study on stratification and thermal layering in blend tanks, which covers how a dense liquid separates in storage and how operators catch it before it leaves the yard. The second is our explainer on Norwesco applicator and leg tanks and the scope those tanks are sold under, which is the reading for anyone weighing a leg tank against a mounted alternative. Neither article is a statement about this part number; this page stays with what the sheet gives, which is 3135 gallons, 952 lb empty, a 1.5 rating, a 3 inch bulkhead with a 2 inch reducer and a siphon tube, a 16 inch vented manway and a 120 F / 48 C ceiling. Take the duty and the density to those two pages, then come back to the numbers here.

Six plants on the sheet, two states on the shipping line

The plant list on this record names St. Bonifacius, Minnesota; Lancaster, Ohio; Griffin, Georgia; Shawnee, Oklahoma; Tooele, Utah; and Fairfield, Texas. The ship-from field, separately, names only Minnesota and Ohio. Six plants and two states is a wide origin spread with a narrower shipping note beside it, and the practical effect is that the lane your tank actually moves on is confirmed at order time rather than read off a page. Freight class and ship mode both read OVS, which is the oversize ticket: 150 inches of length and 88 inches of width is not a tail-lift delivery, so have the machine and the people ready at the appointment rather than after it. Get a real number for your ZIP from the freight cost estimator before you budget; the listed price is before freight. Because this record's crated figures differ from its dimension fields, the receiving check here is a tape measure check: measure the crate as it sits on the trailer, write the figures on the delivery paperwork, and note any disagreement before you sign it. Write the fill date on the manway with a paint marker; it answers the first question anyone asks about a tank.
