Snyder Industries 4500 Gallon ASTM XLPE Double Wall Tank

The 4500 against the 5000 above and the 4000 below

Take the family first, because this capacity exists for a reason and the reason is rarely the gallons. Every tank in this group stands on the same 102 by 102 inch square. The 5000 gallon 5630000N40 on this sheet is 216 inches tall at 3600 pounds. This 4500 gallon tank is 197 inches at 3800 pounds. The 4000 gallon 5610000N30 is 178 inches at 3200 pounds. Three capacities, one footprint, and the only thing that really moves is height, in steps of about nineteen inches. So the question is almost never how much floor you have. It is what is above the spot the tank will stand in: a roof truss, a soffit, a sprinkler main, a duct, a crane rail, a door head or the limit of the equipment that has to set the tank down. Measure to the lowest obstruction over the exact position, add the clearance a fill line and a person at the manway need, and the capacity chooses itself out of that group. Where the height is free, take the bigger shell, because the floor and the pad cost the same. Where it is not, the 4500 is the honest middle: five hundred gallons less than the tallest, five hundred more than the shortest, on the same square. The second thing this record decides for you is the rating. At a specific gravity of 1.9 and 71,307 pounds of maximum contents, this is the heavier-liquid record in the 4500 group, and the lighter record beside it is not a substitute for it. Work the turnover and the delivery quantity through the tank sizing calculator before fixing on 4500 gallons, and take the freeboard discipline from the tank sizing guide. Whatever the tank stands on carries 37,530 pounds of plain water on a 102 inch square, flat, level and continuous, with nothing bridging a void at a corner.

Three 4500s, a 4000 and a 5000 on one sheet

Four of these six rows are 4500 gallons on the identical 102 by 102 by 197 inch shell, and the published weights split into two pairs: 3800 pounds on this record and on the sulfuric acid 5620000N30, 3000 pounds on 5620000N40 and on the black 5620000N46. The sheet gives those weights, the colours and the names and nothing else, and this page prints them rather than explaining them. Where an existing installation, a drawing or a purchasing standard already names a part number, order that number and ask us to check the record against the part before it leaves. The two rows that are genuinely different are the ones at the bottom. 5610000N30 is a 4000 gallon sulfuric acid double wall tank at 178 inches and 3200 pounds, which is nineteen inches shorter again on the same square, and 5630000N40 is the 5000 gallon shell at 216 inches and 3600 pounds, nineteen inches taller. Line the three heights up and the ladder is obvious: 178, 197, 216, all on 102 by 102 inches. That is a rare thing in tank buying and it is genuinely useful, because it means a capacity change on this site is a height question and nothing else. The pad you pour, the bund you build and the floor area you give up do not change as you move up and down the ladder. Pick the rung that clears what is above it.

One threaded manway and nothing else published

• The manway and its vent: 18 inches, threaded, vented, at the top of a 197 inch shell. The vent is what lets the vessel breathe as it fills and empties, and it is the first thing to look at on every visit. Keep it clear and never blank it off.
• The opening as the only access: this is the single published opening on the tank, which makes it the fill point, the sample point, the level access and the inspection hatch all at once. Design a safe route to it before the tank is stood up, not after.
• Freeboard under it: 4500 gallons is the nameplate, not the distance to the manway face. Leave the air space for warming, for a gassing product and for the surge when a line starts. The double wall freeboard sizing article is the one to read before the fill procedure is written.
• Outlet: the field reads "1 Manway / Lid". No pipe size, no bulkhead, no flange, no valve. None is claimed on this page. Tell us what has to connect and we will confirm what this part number carries.
• Inlet: no inlet field is published, so nothing is stated about one.
• Structure: this sheet carries no lifting lug count, no ladder lug field and no flange line count, so no handling point, anchor or restraint is described here.
• Limits: 140 F / 60 C, a specific gravity rating of 1.9, and a 3 year warranty term. That is the whole published set.

The band of wall above the liquid line is where the wear that surprises people begins, and a rising and falling level in a 197 inch shell keeps that band busy; the wall thickness at the vapor saturated headspace article is worth an hour before the inspection schedule is written.

Rooms that take 197 inches but not 216

Four and a half thousand gallons in a double wall shell is a building-constrained purchase more often than a volume-constrained one. It turns up in water and wastewater treatment chemical rooms with a fixed soffit, in process plants where a crane rail or a duct run sets the ceiling, in food and beverage utility rooms, in agricultural and horticultural chemical stores, in mining, metals, pulp and paper plants, and in any site that wants the containment bought with the tank rather than poured around it later. This particular record carries the 1.9 rating and 71,307 pounds of maximum contents, so it is the one to take when the liquid is heavier than water; the lighter-rated record on the same shell is a different purchase and not a cheaper version of this one. Name the contents when you order and check them against our chemical compatibility reference first, because the manway gasket and anything that later connects to the tank are chosen on the chemistry, not on the 4500 gallons.

Lincoln to your ZIP at 3800 pounds

It is moulded at Lincoln, Nebraska and the sheet gives Nebraska as the shipping state. The freight class is 250 and no NMFC number is published. Price the lane to your ZIP with the freight cost estimator; the listed price is before freight. Plan the move around the envelope: 102 inches square and 197 inches tall is a tall, light load, and it is the height and the width together that decide the route, not the 3800 pounds. Walk the path from where the truck can stop to where the tank will stand, and measure the gate, the corner, the overhead line and the door head at the tightest point. This sheet publishes no lifting lug count, so agree the lift arrangement with us and with the crane or forklift operator before the day rather than improvising one against the body of the tank, and never lift by the 18 inch manway. Set it plumb on a pad that is flat, level and continuous under the full base, then fill it with clean water, hold the 37,530 pound load, and read the manway threads, the seal and the base seam all the way round while it stands. Drain it, let it dry, and look inside with a light before any product is introduced. Keep a level reading at each corner of the pad from the day of that first fill; it is the only way to prove later whether a slab has moved. Walk the base after the first hard rain; a pad that shifts shows it at the edge first.
