Snyder Industries 6500 Gallon ASTM Black Double Wall Tank

The footprint this tank buys back

The square this vessel stands on is the whole argument for it. A 120 inch plan is ten feet across, and it holds 6,500 gallons because the shell goes up to 199 inches rather than out. Where the alternative on your site is an 8,700 gallon tank on a 142 inch square, this one gives back a foot and a bit in each direction on the ground for very nearly the same height, and inside a crowded containment area or a process hall that is often the difference between a tank that fits and one that does not. Measure the position both ways before you decide: the plan you can spare, and the clear height at that position once a platform and a fill arrangement are allowed above the manway. The pad still has to be serious. Under this shell sit 54,210 pounds of plain water, or 102,999 pounds at the published 1.9 rating, on those hundred square feet, and a smaller footprint means the same load is concentrated harder rather than spread further. It wants a designed, cured slab, flat and continuous and level across the whole 120 inch square, with no rails, no shim under a corner and no old patch taking an edge. Where the tank is going inside an existing containment area, check that the new pad does not interrupt the fall of the floor to its sump. The 1.9 rating is the second half of the argument. At 102,999 pounds of maximum contents this sheet is written for a product appreciably denser than water at the full 6,500 gallons, which is exactly the case where a site wants a compact footprint and a heavy duty in the same vessel. Its service limit reads 120 F / 48 C and its material field reads high density linear polyethylene; both belong to this part number and neither is borrowed from a shellmate. Settle the usable volume before you order with the tank sizing calculator and the freeboard discipline in the tank sizing guide, because on a contained tank the nameplate figure is not what you get to use.

Four 6500s, a 5500 below and an 8700 above

Four part numbers share this 120 by 120 by 199 inch shell and the sheet gives three of them at 5,300 pounds and one at 4,000. This tank is one of the heavier listings, and the reason to order it rather than the lighter row is the rating line: 1.9 here, carrying 102,999 pounds of maximum contents against 54,210 pounds of plain water. The names differ across the four, the material fields differ, and the sheet explains none of that, so this page prints the rows and leaves the interpretation where it belongs, with the chemistry you describe to us. Order the part number your drawing, your spares list or your existing installation already names, or tell us the product and the strength and let us do the matching. The two outside rows are where a real decision lives, and this family scales in two different directions. 5660000N40 holds 5,500 gallons on the identical 120 inch square at 172 inches, so stepping down costs nothing at all on the floor and buys back better than two feet of height, which is the row for a building with a low roof. 1006400N46 goes the other way, holding 8,700 gallons but on a larger 142 inch square at 197 inches, so the extra capacity is bought entirely in floor area. Work out which of the two you are actually short of, ground or headroom, before you look at gallons; on this family that question answers the purchase on its own.

Height or floor the limit? The table has both shapes; freight to your ZIP is quoted on each row, or call 866-418-1777 with the site.

The opening on top and the flange lines below

• The outlet field: it reads "1 Manway / Lid", and the inlet field is empty. That names an opening rather than a pipe size, so no outlet dimension, thread, bulkhead or valve is published here and none is claimed. Give us the product, the line size and the pump arrangement and we will confirm what this part number carries before pipe is bought.
• Flange lines: this sheet lists two, where the 8,700 gallon listings in the same family list one. That is a published structural figure and it is printed as given; no position, height or size is stated for either line, because the sheet gives none.
• The opening: an 18 inch threaded vented manway, the only opening published. It is the fill, inspection and cleaning route together, so the drop pipe and the level arrangement want planning before the tank is set.
• The vent: listed as part of the manway. A tall, slim vessel moves a lot of air for a given flow because the cross-section is small, so keep the path clear, inspect it whenever the manway is opened, and never restrict it.
• Access: the manway is at 199 inches, which is a fixed ladder or platform and a fall protection arrangement designed with the installation, plus a fill connection brought to ground level wherever the delivery allows it.
• Structure: 8 lifting lugs and ladder lugs are listed. Those are the fittings the sheet publishes and this page names no others.
• The space between the walls: no monitoring port, gauge or alarm is published, so that arrangement is specified separately and written into the inspection routine.
• Limits: 120 F / 48 C, a specific gravity rating of 1.9, and a 3 Year Warranty.

Name the product and its strength at order time, because on a tank with two walls the fitting is still the one route out.

Dense chemical storage where ground is short

A compact plan and the 1.9 rating put this tank on sites where a dense product has to be stored in bulk and the floor area is already spoken for: municipal water and wastewater treatment plants with crowded chemical buildings, power generation and cooling water chemistry, mining and mineral processing reagent storage, metal finishing, pulp and paper, and industrial process lines that dose continuously between deliveries. It is also the size that suits a second product on a site that already runs something larger, held at the point it is used rather than piped across the plant. Four references are worth reading first. The usable volume of a contained tank is not its nameplate figure, per the Captor double wall freeboard sizing guide. The wall works hardest at the vapour line rather than under the liquid, which the wall thickness at the vapour saturated headspace guide explains, and it matters on a slim shell where the headspace sits high above the liquid. How the space between two walls gets tested is set out in the cathodic disbondment testing guide for double wall interstitial spaces. And where the duty is private fire water rather than chemical feed, begin with the fire water reservoir design guide for rural and remote sites; no claim about that duty is made here.

Fifty-three hundred pounds on a 199 inch shipment

The sheet lists one plant, Lincoln, Nebraska, and one ship-from state, Nebraska. Freight is LTL at class 250 with no NMFC number, and the load is 120 by 120 by 199 inches at 5,300 pounds. Price your own lane with the freight cost estimator; the listed price is before freight. No crane, rigging, permit or escort detail is published on this sheet and none is claimed on this page. What is worth saying is that a ten foot square load standing over sixteen feet tall is easier to route than the 142 inch shells and still not a pallet truck job: measure the gate, the door and the overhead services, and confirm the offloading equipment has the reach as well as the capacity before the truck is booked. Take it under the base, never by the manway, and keep it upright through the site. Set it plumb on the cured, level surface in its final position, check it in two directions while it is empty, and confirm the whole 120 inch footprint is bearing before a pipe is connected. Fill it with clean water, hold the 54,210 pound load, and read the manway seal, the base line and the pad in good light while it is loaded. Drain it, dry it, open the space between the walls and record the date and the part number on the shell. Then check the base again a week after the first working fill; a pad settles a little, and a tall tank on a small square shows that at the edge first. The vent screen is the cheapest part on the tank and the one that saves it; look at it every time the manway opens.
