Snyder Industries 16500 Gallon Heavy Duty Heavy Duty Vertical Storage Tank

The pad, the cables and 21 feet of standing wall

Site this one before you price it. At 257 inches the top head sits 21 feet 5 inches off the slab, which puts it above most single-story roof lines and into the same conversation as the overhead service drop, the crane reach and the fire department access lane; measure the clearance above the manway, not just to it, because a fill line, a vent and a person with a rail all live in that space. The base is a 142 inch circle, 11 feet 10 inches across, and a rotationally molded floor bears on every part of the slab it touches and nothing else, so a low corner or a hollow under the middle is not a blemish, it is the new bearing point. Engineer the slab to the framework in the concrete pad sizing guide, pour it wider than the tank, level and in full contact, and size it for 261,459 pounds rather than the 137,610 pound water figure if the liquid is denser than water. Then the air. An empty tank of 3,000 pounds with 21 feet of wall is a sail for the whole window between delivery and first fill, and that window is where these tanks get lost, so the ladder lugs and the flange lines the sheet names go to cables or to anchors set in the pad while the tank is still light, tight before the first gallon, checked after the first windy week and again after the first full summer, because polyethylene grows in the sun and the cable that was tight in spring is slack in August. Where the liquid is regulated the tank stands inside a berm sized to it. Run 16,500 gallons against your draw and your delivery interval in the tank sizing calculator before you commit to a vessel this size, and take the reserve and the freeboard a warming liquid needs from the tank sizing guide.

One 142 by 257 inch shell, and the 165 inch tanks beside it

The number that separates this tank from the rest of its own shell is on the sheet in plain sight: 3,000 pounds empty where the C34, the C37-BLACK and the N40 are each listed at 5,100 pounds for the same 16,500 gallons in the same 142 by 257 inch shell. That is the sheet's own record of the difference, and it is the reason to take this one when the receiving equipment, the crane picks and the freight bill all have to come down and the liquid does not need a heavier wall than 1.9 covers. Those three are the black and cross-linked grades in the shell, each rated as its own sheet says, and the two black ones are the buy when light spoils the liquid, because this tank is natural white and passes light. Off the shell the trade is shape against volume: the 3030100C26 lays 15,000 gallons down to 184 inches on a 165 inch base, which is the tank when the roof is the constraint rather than the yard, and the 3030000N49 stands 18,800 gallons at 242 inches on that same wider base for a site that simply needs more in one vessel.

The sheet lists the outlet as 26

• Outlet: the sheet lists the outlet as 26. That is the field as published, it is not a pipe size, and we will not print it as one. Tell us the liquid and the pipe you are tying into at order and the base fitting, gasket and bolting are specified then.
• Access: 18 inch threaded, vented manway on the top head, 257 inches up, which means fixed access with a rail rather than a leaned ladder; fill through a dip tube to the floor so a delivery does not free-fall the height of the tank and aerate the load, and run the vent outdoors on anything that fumes, sized to the delivery pump rather than to the fitting.
• Body: ladder lugs and two flange lines, as the sheet lists them. Service limit 120 F / 48 C.

With the base fitting open on the sheet, run the job backwards from usual: specify the draw-off with the order, design the pipe to what actually lands on the tank, and do not pre-buy a valve. Whatever it turns out to be, 21 feet of liquid standing above it is the most suction head in this catalog and it cuts both ways. A transfer pump set below the outlet runs flooded to the last few inches, which is the upside. The downside is that the same column sits on the fitting, the first joint and the first valve every hour of every day, and with a dense liquid at 261,459 pounds it sits harder than water would, so the connector to hard pipe is flexible, the first valve rides on its own support off the pad, and nothing rigid bolts to a polyethylene wall. A low level float stops the pump before it pulls air. Keep the manway closed between deliveries so vapor stays in and rain stays out, name the one liquid on the wall in letters readable from the gate, and put a light on the band of wall above the liquid line every time the lid comes off, because on a tank this tall that band is the part nobody sees from the ground. Where the site freezes, trace or wrap the valve and the first pipe run; the body takes ice from the top down without harm.

Most of two tanker loads in one vessel

Buyers at 16,500 gallons are buying delivery economics, not storage. A water or wastewater plant that would rather take full loads than partial ones, a co-op that buys a fertilizer solution on a season price and needs somewhere to put it, a mine or a mill on a bulk process liquid, an industrial site consolidating a row of smaller tanks into one vessel with one pad and one set of plumbing. Where site rules put a second wall around a tank this size, the Captor double wall freeboard guide works out what containment costs in usable gallons, which is the figure people forget when they draw the berm. Water sits well inside a wall rated 1.9, but a fire reserve is designed as a system with its own sizing and freeze rules rather than bought as a vessel, and the fire-water reservoir design guide is the honest place to start on that job. Where bulk storage sits between the treatment stages of a reuse train, the industrial water reuse tank topology article places a vessel this size in the sequence and says what has to be true upstream of it.

Lincoln to the pad, a long load at class 300

The 5380000C126 is molded at Lincoln, Nebraska and moves as freight at class 300 as the sheet lists it, shipping at 142 inches by 142 inches by 257 inches. Better than 21 feet on the deck and nearly 12 feet across is a permitted load rather than a freight quote, so the route is as much of the decision as the rate: walk the gate, the turn into the pad and the overhead lines before delivery day, because a load this long does not reverse out of a bad approach. The freight cost estimator prices the lane to your ZIP, and the listed price is before freight. A crane stands 3,000 pounds up with straps under the body and never a hook through the manway, landing on the anchors that were set with the pad, with the cables tight before the crane releases. Water test before product: fill to the manway, hold it, read the base, the pad edge and whatever fitting was specified at order, then drain and dry. On a tank this tall, plan the first fill for a morning with no wind and two people on the ground. Check the strap tension a week after the first fill; a tank settles a little, and the strap that was tight is loose.
