Snyder Industries 6600 Gallon ASTM Black Heavy Duty Vertical Storage Tank

Chowchilla, California, class 300, and a mid-height shell rated for density

The plant on this sheet is Chowchilla, California, so the shortest lane belongs to a Central Valley or West Coast buyer and an eastern site is paying for miles under a 6,600 gallon shell at class 300; either way the load is 2,100 pounds measuring 120 by 158 inches, a permitted piece that wants the route into the yard walked before the delivery is booked. The shell itself is the middle option in the family, and that is deliberately useful: 158 inches clears a chemical building that a taller tank misses while still standing on a 120 inch circle, so it needs ten feet of pad and not twelve. That pad, though, answers to the rating rather than to the gallonage. Water alone puts 55,044 pounds on the circle, this sheet rates the wall to 104,584 pounds of contents, and a molded floor bears across the whole slab rather than on a ring, following a low corner instead of spanning it: engineered, level, in full contact under the entire base, per the concrete pad sizing guide, with the pounds per square foot worked out for the liquid you actually intend to store and a berm sized to the tank wherever that liquid is regulated. Thirteen feet of empty shell on a ten foot base still catches wind, so the bands go to anchors set in the concrete before the first fill and get re-tensioned after the first hot spell and again in the fall. Run 6,600 gallons against your dosing rate and delivery interval in the tank sizing calculator, and take the reserve and the thermal freeboard from the tank sizing guide.

The 6,600 shell in three grades, plus a neighbour that states its own rating

The 5300400 shell splits into two weights, this tank and the N42 at 2,100 pounds and the N40 and N46 at 1,900, and the case for this row is straightforward: it is the 1.9 rated wall on a shell that needs only a ten foot circle, which is the specification a plant reaches for when the liquid is dense and the yard cannot give up twelve feet of floor. The N40 and N46 are rated as their own sheets say and are the lighter tanks to set for a liquid near water weight. The two neighbours are worth reading carefully. The 7140000N33 holds 6,500 gallons at 153 inches and 1,450 pounds, and it is the only tank on this sheet that states a rating in its own name, 1.35 SG, which is a genuine middle step between a water-weight wall and this one; if your liquid sits in that band it is the honest comparison to make. The 7140000C26 takes 6,900 gallons on the same 153 inch height at 1,300 pounds. Buy this tank when density is the requirement, the building clears 158 inches, and the pad is poured for the contents figure rather than for water.

Thirteen feet two inches to the manway, and a lid that needs a platform

• Access: an 18 inch threaded, vented manway at the top of 158 inches of shell. What reaches it is a fixed ladder off the ladder lugs the sheet lists, a platform with a rail and a tie-off point; on a dense liquid nobody should be working up there without both.
• Outlet: the sheet gives the outlet as one manway and lid, with no bottom fitting diameter, material, thread or gasket, so the draw-off is specified at order. Nothing is drilled at the plant, which means the fitting goes where your pump wants it instead of where a catalog put it.
• Handling: eight lifting lugs are listed for setting the tank, with ladder lugs and two flange lines.
• Service limit: 120 F / 48 C. Warranty: 3 year.

With the lid 158 inches up, the tank sits in the awkward middle: too tall for a step and not so tall that anyone plans the access properly, which is how a fixed ladder ends up being added a year later. Put it in at the start, and design the rest of the installation so the ladder is rarely needed: level off a sender read at grade, sample point piped down to waist height, vent screen visible from the pad. Because the draw-off is not drilled at the plant, place it low and place the pump lower; then the last inches leave the tank instead of becoming a heel, and the pump holds its prime through the working range. On a 1.9 duty the base connection carries the most load on the whole installation, so a flexible connector goes between the bulkhead and hard pipe and the first valve stands on its own support off the pad rather than hanging on the fitting. Fill down a dip tube to the floor so a dense liquid does not free-fall into the headspace, size the vent for the delivery pump, fit a low-level float, keep the lid latched between fills, and name the one liquid on the wall. Where the site freezes, protect the valve and the first pipe run; the shell takes ice from the top down.

Dense dosing chemistry in a mid-height chemical building

At 6,600 gallons with a 1.9 rating, this is a dosing and bulk-holding tank for something heavier than water, sized for a plant that takes full deliveries but does not have room for the largest shells: a municipal water or wastewater system holding a dense coagulant, a plating or finishing shop with acid or caustic feeding a line, a fertilizer distributor breaking bulk, an oilfield or mining yard with brine, and a manufacturer keeping a heavy feedstock beside the machine that draws on it. The black wall passes no light to the liquid and runs warmer than a white one in the sun, so a liquid that must stay cool wants the shade side of the building. A fire reserve is sized by its own discipline and belongs in a water-duty vessel, which the fire-water reservoir design guide sets out, and not in a wall bought for density. Where a plant banks rinse water, rainwater or condensate between treatment stages, the industrial water reuse tank topology article shows where a vessel this size belongs in the train.

The California lane, eight lifting lugs, and one water test

Freight is class 300 as the sheet lists it, out of Chowchilla, California, with 2,100 pounds measuring 120 by 158 inches riding as a permitted piece. The freight cost estimator prices that lane to your ZIP, and the listed price is before freight. Straps go to the eight lifting lugs the sheet lists or under the body, never a hook through the manway, and the tank lands in one move on anchors that were set before the truck arrived. Fill it with water to the manway, hold it a shift, and read the pad edge and the draw-off you specified before any product goes near it. Write the part number and the fill date on the maintenance log the day it lands, because four parts in this shell measure the same and only the sheets tell them apart. Tape a copy of the spec sheet inside the control panel door; the next person to touch the tank will not have the box it came in.
