Snyder Industries 5600 Gallon ASTM XLPE Black Heavy Duty Vertical Storage Tank

Eleven feet ten inches of circle, and 88,738 pounds on it

This is the shape you buy when the roof is low and the yard is wide, and the site trade is exact: almost nothing to strap, and a great deal of pad. A shell 102 inches tall keeps its centre of gravity below a person's shoulder and gives the wind very little to push against, and a manway at that height is reached from a short platform or a sturdy step rather than from a caged ladder. In exchange, the floor is an eleven foot ten inch circle and every pound lands on it, because a rotationally molded floor bears on its whole floor and nothing else: 46,704 pounds with plain water in it, and 88,738 pounds if the liquid works the 1.9 rating this sheet gives. A wide tank on a slab with one low corner puts its weight on that corner, so this pad in particular is engineered to the concrete pad sizing guide, poured level and cured, in full contact under the whole floor, inside a berm sized to the tank where the liquid is regulated. Strap it anyway while it is empty, because a black shell expands and contracts in the sun every day and 1,350 pounds of empty tank will still move in a gust. The black wall is what keeps daylight out of the liquid and takes the ultraviolet that ages a pale one, and it also means you read the level with an instrument rather than with your eyes. Check 5,600 gallons against the feed rate and the delivery interval in the tank sizing calculator, and take the reserve and the thermal freeboard from the tank sizing guide. Whether crosslinking is the right resin call for the chemistry is worked through in the crosslinked against high density polyethylene article.

Four walls in the 5250000 mold

Four walls come out of this one 142 by 102 inch mold at the same volume, listed separately and each rated as its own sheet says, and the case for this one is density in a low building. The 1.9 figure on this sheet and the 1,350 pounds of wall behind it are what a brine or a concentrate needs; the 5250000N46 is the lighter wall in the identical shell at 1,150 pounds and is the honest buy for ordinary chemistry, and the 5250000N42 and 5250000N40 are the other two walls in the same mold. Step out of the shell and the shape changes rather than the volume: the 7000000N40 stands 5,500 gallons up at 132 inches on a 120 inch base, which is the tank for a narrow floor and a roof that can take eleven feet, and the 7000000C34 holds 6,000 gallons in that same taller shape. Nothing here is a compromise on capacity; they are four footprints and you pick the one your building already has.

Outlet given as 10 on the sheet

• Outlet, first, because it is read wrong most often: the sheet lists the outlet as 10. That is the field as published and it is not a pipe size, and no bottom fitting diameter, material, thread or gasket appears anywhere on this sheet. We print it as it stands. Name the liquid and the draw-off arrangement you want at order and we confirm what this shell takes, in what material, with what gasket, before a hole is cut.
• Top opening: an 18 inch threaded, vented manway at the top of a 102 inch shell, which is the one genuinely easy access point in this slice, but it still wants a proper platform and a lid that goes back on threaded rather than laid over the hole.
• Fill and vent: a dip tube to the floor, a vent piped outdoors on anything that fumes, and the vent sized to the delivery pump, because a wide tank takes a fast fill and the headspace has to breathe as fast.
• Handling and hardware as listed: ladder lugs and one flange line.
• Service limit: 140 F / 60 C. Warranty: 3 year. Rating: specific gravity 1.9 as the sheet gives it.

A low tank gives you less suction head than a tall one, and that changes the pump work rather than the tank work: mount the transfer pump below the base connection so gravity keeps it flooded, keep the suction run short and straight, and fit a low-level float so the pump stops before it draws air rather than after it has. The first valve still rides on its own support off the pad with a flexible element between the tank and the hard pipe, and nothing rigid bolts to the shell. Because the manway on this shape is easy to reach, it is the one people open too often; keep it shut between deliveries so vapour stays in and rain stays out, and read the band of wall above the liquid line with a light at every opening, for the reasons the vapour-saturated headspace wall article lays out.

Low chemical buildings and windy yards

A dense liquid under a low roof is the duty this molding owns: a brine or a concentrate at a plant whose chemical building was never built tall, a heavy process solution in a shed, a fertilizer solution on an exposed pad where a tall tank would need engineered anchors and this one barely needs bands. Where a site rule or an insurer wants the liquid inside a second wall, the double wall freeboard sizing guide works out how much usable volume a contained vessel really returns, which is never the figure on the label. Water at 8.34 pounds per gallon sits far inside this rating, but a private fire reserve is a separate specification in a water-rated vessel, and the fire-water reservoir design guide explains why the two do not substitute for each other.

Philippi, West Virginia, class 300

Freight is class 300 out of Philippi, West Virginia at 1,350 pounds shipping weight as the sheet lists it. The thing to plan for here is width, not weight: at 142 inches across, this tank rides as an over-width load that a carrier handles accordingly, and the delivery site needs room for the truck to turn and for a forklift with long forks or a small crane to take it off the side. Price the lane with the freight cost estimator before the requisition is cut, and the listed price is before freight. Lift with straps under the body, never a sling through the manway, and set it on a cured pad in one move rather than dragging it into position. Then fill it with water to the manway, hold it, walk the full circumference of the base and the pad edge, and drain and dry it before the working liquid arrives. Save the pallet: a tank this wide that ever has to move again is far easier to move on it. Chalk the full-water line on the outside after the first fill; it is the level every later reading gets checked against.
