Snyder Industries 16500 Gallon Black Vertical Storage Tank

Out of Lincoln at class 300, and what the 1.5 rating buys instead

Molded at Lincoln, Nebraska and shipped at class 300, this tank rides exactly the same lane as the heavier wall in the same shell, which is the useful thing to know about it: freight is not the difference between them, the rating is. Both are 142 inches across and 257 inches long on the deck, both travel as permitted over-dimensional loads, and both want the same route walk before the order goes in, so choose on the liquid and let the lane fall where it falls. Get the lane priced to your ZIP in the freight cost estimator anyway, early, and treat the listed price as before freight, because at this size the freight is a real fraction of the project. What the 1.5 rating buys you is the right pad for the liquid you actually have: 206,415 pounds of allowed contents where plain water in this shell is 137,610, all of it bearing on a 142 inch circle because a rotationally molded floor carries on its whole floor. Engineer the slab to the concrete pad sizing framework, level and in full contact, inside containment sized to the tank where the liquid is regulated. Twenty-one feet of empty shell on an eleven foot base is a sail, so band it to structure or to slab anchors before the first fill, then check the bands after the first windy week. Black polyethylene passes no light into the liquid and takes the ultraviolet that ages a pale shell outdoors; the cost is that you cannot see the level, so a sender belongs in the install. Run 16,500 gallons against your draw in the tank sizing calculator, and take the reserve and the thermal freeboard from the tank sizing guide.

Same 257 inch shell, lighter rating, 206,415 pounds

Everything in the top four rows drops onto the same pad and takes the same 18 inch manway, so the only question is which wall the liquid needs. Buy this one when the liquid is no heavier than about the density this sheet is rated for: 1.5, or 206,415 pounds of contents, and paying for more wall than that is paying for nothing you will use. The 5380000C34 is the tank in this shell carrying the heavier rating on its own sheet and it is the one to move to if a density survey comes back heavier than expected; the 5380000N40 is the other wall listed in this footprint, rated as its own sheet says; and the 5380000C126 is listed at 3,000 pounds empty against this tank's 5,100 in identical dimensions, which the sheet gives and we print without interpreting. If the height is what the site cannot take, the 3030100C26 lays 15,000 gallons down to 184 inches on a 165 inch base, and if the inventory needs to be bigger the 3030000N49 holds 18,800.

An 18 inch manway 257 inches up

• The height of the opening is the first thing to design around: the listed access is an 18 inch threaded, vented manway at 257 inches, which is a fixed platform with a rail and a gate, or a caged ladder to a landing, and a permanent fill connection landed at the manway so no delivery hose is ever lifted up a twenty-one foot shell. Eighteen inches passes a cleaning wand, a level probe and a vent line together; it passes no person, so there is no interior entry on this tank at all.
• Outlet: the sheet's outlet field reads "26" and there is no pipe size on the sheet. A bare number is not a diameter, so the honest statement is that the sheet lists the outlet as 26 and the draw-off is specified at order, once you name the liquid and the arrangement you need, in writing, before anything is cut.
• Fill and vent: a dip tube to the floor so the incoming stream does not free-fall the full 257 inches and foam against the headspace, the vent run outdoors on anything that fumes, and the vent sized to the delivery pump.
• Service limit: 120 F / 48 C. Warranty: 3 year. Rating: specific gravity 1.5 as the sheet gives it.

Because you cannot see through a black wall, the routine has to replace the eye. Gauge with a sender and a readout at the ground, cross-check it against a stick through the manway on a schedule, and put a light on the band of wall above the liquid line every time the cover is off, because that band is where a tall tank ages first and the liquid-side inspection nobody does would not find it anyway. Keep the manway threaded shut between deliveries so vapour stays in and rain stays out. At the base, whatever is plumbed there sits on its own support off the pad with a flexible connector to hard pipe, because 257 inches of standing liquid is real pressure on a fitting and a rigid run feeds thermal movement and pump vibration into the shell. Label the wall with the one liquid inside.

16,500 gallons of light liquid in the dark

A black wall at this volume goes where the liquid has to stay out of the light and the quantity is a tanker at a time: a municipal plant holding a bulk feed chemical that sunlight degrades, an agricultural retailer with a solution that has to hold its strength through a season outdoors, a food or beverage plant holding process water or a cleaning solution where nothing should grow in it, and a reclaimed water or process water buffer on an open pad in full sun. It is also the tank people buy when they are consolidating: one vessel on one pad with one set of piping is easier to keep honest than four. Water at 8.34 pounds per gallon sits well inside this rating, but a private fire reserve is its own specification in a water-rated vessel, which the fire-water reservoir design guide sets out plainly. Where a reuse system needs a bulk dark holding stage between treatment steps, the industrial water reuse tank topology article shows where a vessel of 16,500 gallons belongs in the train.

A 142 inch load on the deck, and the first fill

Class 300 and 5,100 pounds shipping weight from Lincoln, Nebraska is what the sheet gives, shipping at 142 inches by 142 inches by 257 inches, which is the cube the carrier prices rather than the weight. Unload with a crane or a heavy forklift, straps under the body, never a sling through the manway, and put it on the finished pad inside its containment the first time it is set down. Fill it with water to the manway and hold it there long enough to walk the base twice and look at the pad perimeter and every fitting, then drain and dry it before the working liquid arrives; the water hold is the only inexpensive test this installation gets. Once the tank is standing full and quiet, leave it alone for a day before the plumbing goes on, because a settled tank is a quiet one and a shifted pad shows itself in that first day. Keep the shipping pallet, because a tank this wide is easier to move again on it than off it. Once it is full and holding, leave it alone for a day before the plumbing goes on; a settled tank is a quiet one.
