Snyder Industries 4000 Gallon Black Heavy Duty Vertical Storage Tank

Two black 3,650s, forty pounds apart

Snyder lists this shell in two general grades, and the sheet gives the C26 forty pounds more resin than the C37; both are rated the same, both are black in the BLACK suffix, and the difference is what a buyer sees on the scale and nothing else the sheet states. Full at the rating it puts 57,838 pounds on a 102 inch circle: a full-contact engineered slab, sized per the concrete pad sizing guide, inside a berm scaled to the tank, with the empty tank strapped against wind before the first fill. Black polyethylene absorbs the ultraviolet that ages a white wall and passes no light to the liquid; it runs warmer in the sun, so shade if the chemical must stay cool, and it hides the level, so a sender read at the ground is the gauge.Feed rate times delivery interval is the volume, and the tank sizing calculator does that arithmetic; the reserve and the thermal freeboard on a dense liquid are in the tank sizing guide.

Grades on the 102 x 126 inch tank, and the 3,500 and 3,900 beside it

The 8190000C26 is this tank in white for indoors, where the level shows through the wall; the C37-BLACK and C37 are the lighter molding in black and white. The 32288 is the 3,500 gallon water tank on a 96 inch base at the same height, and the 5190000N40 puts 3,900 gallons on a 90 inch base at 163 inches in the other chemical wall for the narrowest floor.

Openings on a chemical tank

• Outlet: 3 inch polypropylene female NPT bulkhead fitting, at the base; tell us the liquid when ordering and the fitting is matched to it, with a flanged transition, a flexible connector to hard pipe, and the valve supported off the pad in the material the chemical calls for.
• Access: 18 inch threaded, vented manway, 126 inches up; a short platform with a rail for anyone who opens it. Fill by dip tube so the liquid does not foam, vent to outdoors on a fuming chemical, and match the vent to the delivery pump rather than trusting a stock cap.
• Service limit: 120 F / 48 C.

Ten and a half feet of liquid above a 3 inch outlet is a strong flooded suction, and the outlet drains a full tank in a working shift; mount the pump below the outlet for a gravity prime, and fit a low-level float so it never pumps air. One chemical, one label, one closed manway; and at each opening a light on the wall above the liquid, where a chemical tank shows its age first. In a freezing climate the outlet valve and the first run of pipe get heat trace or insulation; the tank body itself can ice from the top down and come to no harm.

Where a black 3,650 goes

Coagulant or caustic at a small water plant, acid at an industrial plant on an open pad, brine at a food plant, and a fertilizer solution tank at a co-op where the liquid stands in the sun. The Captor double wall freeboard guide is the read for a site that needs containment in the tank rather than around it; the usable-volume penalty at this size is spelled out there. A fire reserve wants a water wall, which the fire-water reservoir design guide covers, and where a reuse system stores treatment chemical between stages, the industrial water reuse tank topology article shows where a tank this size sits.

From Marked Tree, as a permitted load

The 8190000C26-BLACK ships from Marked Tree, Arkansas as freight at class 300 as the sheet lists it; at 126 inches long on the deck it is a permitted load, and the freight cost estimator prices the lane to your ZIP, with the listed price before freight. A crane or a forklift with long forks stands 790 pounds up with straps under the body, never through the manway. Fill it with water to the manway once and hold it, watching the pad edge and the outlet fitting, then drain and dry before the chemical goes in, and the log takes the date and strength of every load after that. Save the pallet; a tank that ever has to move again is easier to move on it.
