Snyder Industries 1900 Gallon ASTM XLPE Heavy Duty Vertical Storage Tank

The duty: a dense load taken 1,900 gallons at a time

The 1.9 rating on this sheet is the purchase. A grower buying a concentrated fertilizer solution, a plating shop with an acid, a plant holding a brine through the winter, a processor with a sanitizer at working strength: those liquids weigh more than water, and the sheet's 30,107 pounds of contents is what the wall is rated to hold where the same 1,900 gallons of water is 15,846 pounds. The delivery is a small tanker or a route truck, one fill covering weeks of use, and it arrives at a manway 119 inches up, so a fixed platform with a rail and a fill line plumbed to the tank beat a ladder and a hose every time. What the buyer gets in return for the height is floor space: 1,900 gallons on a 72 inch circle leaves aisle and working room that a wide tank takes. Underneath, all of that weight passes into the slab through a floor that bears across its whole area, so the pad is engineered to the concrete pad sizing guide, level, in full contact and inside containment where the liquid is regulated. Size the volume against your own consumption with the tank sizing calculator, and take the reserve and the freeboard a dense warm liquid needs from the tank sizing guide.

Four grades in the 1780200 shell

Four tanks share this exact 72 by 119 inch shell and this exact 1,900 gallons, and the sheet separates them by weight: this one and the 1780200N48 are listed at 520 pounds, the 1780200N40 and 1780200N46 at 445. The reason to buy this one rather than the 1780200N40 is the 1.9 rating this sheet gives it, where the N40 is rated lighter on its own sheet, and the reason not to is that a light liquid never asks for it. Each of the other three carries the rating printed on its own sheet, and we do not interpret the suffixes beyond that. Off the shell, the SII-32118 puts 1,600 gallons on an 86 inch circle at 71 inches for a room with a low ceiling, and the 5050000C26 holds 2,000 gallons at 88 inches on a 90 inch circle.

Pump duty on a 1.9 liquid

• Pump: a dense liquid punishes a badly placed pump. Every foot of suction lift costs more on a 1.9 load than on water, so the pump belongs below the tank base where the 119 inch column primes it by gravity and holds it flooded almost to the floor. Keep the suction line short and straight, choose the impeller and seal for the liquid rather than for the flow rate alone, fit a low-level cutoff so it never draws air, and stand the first isolation valve on its own support so vibration and thermal movement stay out of the wall.
• Outlet: the outlet entry on this sheet reads "1 Manway / Lid" and lists no plumbed connection, so no fitting size is claimed. Name the liquid and the pump duty at order and the bulkhead fitting, gasket and bolting are quoted with the tank, with a flexible connector into hard pipe.
• Access: 18 inch threaded, vented manway at 119 inches, which is a platform, not a step stool. Fill through a dip tube to the floor so a dense liquid is not dropped onto the surface, vent outdoors on anything that fumes, and size the vent to the filling pump.
• Service limit: 140 F / 60 C.

Whether crosslinking is earning its keep against your particular chemistry, or whether you are paying for a property the liquid never tests, is worked through in the crosslinking and chemistry duty article, and it is a better guide than a rating number on its own. Day to day: lid shut, one liquid named on the wall in paint, a light on the headspace band at every opening, and trace or insulation on the valve and first pipe run where it freezes.

The 1.9 buyers at 1,900 gallons

Growers and co-ops with concentrated fertilizer solutions, metal finishers with acid feeds, food and beverage plants with sanitizers at strength, industrial sites holding brine, water plants dosing a dense treatment chemical. Water sits far inside the rating, but a private fire reserve is a different design problem and the fire-water reservoir design guide explains what that job asks for. Where the regulated liquid has to sit inside a second wall instead of a bermed pad, the Captor double wall freeboard guide gives the usable volume that survives freeboard and thermal expansion at this size, which is the number to design the feed system around.

520 pounds out of Chowchilla at class 300

It ships from Chowchilla, California at 520 pounds in a 72 by 72 by 119 inch shipment at freight class 300, and the freight cost estimator quotes that lane to your ZIP with the listed price before freight. Unload with straps under the body, never through the manway, and stand it with equipment rather than with people. Anchor it before it is left alone, because an empty tank ten feet tall on a six foot circle is the easiest thing on the site to tip and the hardest to explain afterwards. Water-test to the manway, hold it, walk the base twice, drain and dry before the chemical arrives. Then log the date, the plant it came from and the rating on the sheet in the same place you keep the pump curve, because those three facts are what the next person will need. Walk the base after the first hard rain; a pad that shifts shows it at the edge first.
