Snyder Industries 1550 Gallon Black Heavy Duty Vertical Storage Tank

Four 1,550s in one shell: the case for this one

The 1840000C26 is this tank in white, at the same 335 pounds, for a site that wants to read the level through the wall. The N48 and N49 are the black tanks in the other walls, the N48 in cross-linked polyethylene, listed at 305 pounds and rated as their own sheets say. This C34 is the one to buy when the liquid is dense and light-sensitive at once: ferric in the sun, a concentrated coagulant on an open pad, a brine that stands outdoors. The black wall does what a white wall cannot, and the heaviest rating does what the lighter walls cannot; nothing else in the shell does both. The shape is the other reason. A tank ten feet tall on a five foot base holds 1,550 gallons on the floor a small tank takes, so it goes in the corner of a chemical room, beside a filter skid, or in the strip between a building and a fence. Full at the rating it puts 24,561 pounds on that small circle, the most weight per square foot in this batch, so the slab is designed to the concrete pad sizing guide and in full contact with the floor, and the empty tank is strapped to structure before the first fill, because ten feet of polyethylene on a five foot base is a sail. The tank sizing calculator confirms the volume against feed rate and delivery interval, and the tank sizing guide covers the reserve and the freeboard a dense liquid needs when it warms.

The 64 x 124 inch tanks, and the low 1,500 and 1,600

The 1770000C34 is the same black heavy wall laid down to six feet on an 86 inch base, for the site with floor and no height; the 32118 is the white 1,600 gallon water tank on that same base at 71 inches. Between this tank and the 1770000C34 the choice is the room, not the liquid.

Air in, air out, on a tall narrow tank

• Vent: the 18 inch manway is vented, and on a tall narrow tank the vent earns its keep twice. Filling from a truck, the pump displaces air faster than a small vent passes it and the shoulder bulges; drawing down with a transfer pump, a starved vent pulls the wall in, and a slim shell shows it first. Size the vent to the fastest pump the tank will see, screen it, and pipe it outdoors on a chemical that fumes. The atmospheric vent capacity guide works the arithmetic for verticals of this size.
• Headspace: fill to the shoulder, not the manway. A dense chemical in a black wall grows as the day warms, and ten feet of column moves the level a long way for a small change in volume.
• Outlet: 2 inch polypropylene female NPT bulkhead fitting at the base, matched to the liquid at order; a flanged transition where the chemical calls for it, a flexible connector to hard pipe, and the valve supported off the pad.
• Access: 18 inch threaded, vented manway, 124 inches up; a platform with a rail for anyone who opens it, and a dip tube for the fill so the liquid is not dropped ten feet.
• Service limit: 120 F / 48 C.

Ten feet of liquid above a 2 inch outlet is the strongest flooded suction of any tank this size, and a feed pump mounted below the outlet never loses prime; a low-level float shuts it off before it draws air. A black wall shows no level, so a sender read at the ground is the gauge. Where winters freeze, the valve and the first pipe run get trace heat or insulation; the body ices from the top down without harm.

Corners, strips and tall chemical rooms

Ferric or alum in the corner of a water plant's chemical room, acid beside a boiler feed skid, a dense brine at a food plant, a coagulant day tank on a narrow pad at a well site, and any plant where the floor is spoken for and the ceiling is not. This is a chemical wall, not the tank the fire-water reservoir design guide describes for a fire reserve, though water is well inside its rating. The industrial water reuse tank topology article shows where a chemical tank this size doses between the storage stages of a reuse train.

Three plants, class 300, and standing it up

The 1840000C34 ships from Lincoln, Nebraska, Marked Tree, Arkansas or Philippi, West Virginia, whichever is nearest, as LTL freight at class 300; the freight cost estimator quotes the lane to your ZIP, and the listed price is before freight. It travels on its side and is stood up on the pad with straps under the body, never a chain through the manway; two people can walk 335 pounds, and a 64 inch tank passes a double door. Strap it to structure before it is filled, fill it with water to the shoulder and hold it a day, watching the pad edge and the outlet fitting, then drain and dry before the chemical goes in. Once it is full and holding, leave it alone for a day before the plumbing goes on; a settled tank is a quiet one.
