Snyder Industries 5500 Gallon ASTM XLPE Vertical Storage Tank

Spring delivery at the co-op

The co-op and the ag retailer are the buyers, and the duty is a fertilizer solution or a crop-protection carrier that arrives by transport in the weeks before planting and leaves by the nurse tank load every morning for a month. Delivery is a truck at the barn door, a hose to the fill connection, the driver's pump running for most of an hour, and a tank that has to take the whole drop without anyone climbing to watch the level, which is where a white wall earns its place: the liquid line shows through natural white polyethylene as a shadow, so the yard hand reads it from the ground. Eleven feet tall on a ten foot base, this is the 5,500 that fits under a pole-barn eave with room for the vent, the tank a taller shell of the same volume does not replace. Full of water it puts 45,870 pounds on a 120 inch circle, about twenty-three tons, and full at the rating 68,805; a rotationally molded floor bears on the whole pad, so the slab is engineered per the concrete pad sizing guide, level and in full contact, with a berm sized to 110 percent of the tank where the liquid is regulated. Strap it to the barn frame while it is empty, because a farm tank spends half the year empty and an empty tank walks in the wind. The tank sizing calculator checks 5,500 gallons against the daily draw and the transport schedule, and the tank sizing guide covers the reserve and the freeboard a solution needs as the barn warms in May.

The 7000000 family and the low, wide alternatives

Pick this one when the solution is no denser than the rating and the operator wants to see the level. The N42 is the heavy-duty wall in this shell, listed on the sheet at 750 pounds, which the sheet gives and we print; the N46 is the black wall at this weight for a liquid that stands in the sun, and the N48 is the black heavy-duty wall at 1,450 pounds. When the eave is lower still, the 7000400C26 lays 5,400 gallons down to 91 inches on a 142 inch base, and the 5250000N40 puts 5,600 gallons at 102 inches on the same wide base in this white wall.

Loading nurse tanks from the outlet

• Outlet: the sheet's outlet field reads 24, and we print it as given; name the liquid at order and the fitting size, gasket and bolting are confirmed for it, with a flanged transition, a flexible connector to hard pipe, and the first valve on its own support off the pad.
• Access: 18 inch threaded, vented manway, 132 inches up, reached from a short platform or a stable ladder tied to the frame; fill down a dip tube, and size the vent to the transport pump, because a truck pump moves air faster than a stock vent passes it.
• Service limit: 140 F / 60 C.

The transfer pump on a farm tank runs hard for an hour every morning and then sits, so it gets a flooded suction from an outlet at the base with the pump mounted below it, where eleven feet of solution keeps it primed through the season. A self-priming pump can sit at pad level, but it still wants the shortest suction line the yard allows and a strainer ahead of it, because fertilizer solutions carry fines that settle over a winter and come off the floor on the first fill. Fit a low-level switch that stops the pump when the tank runs down; the last few inches of a fertilizer tank are where a centrifugal pump cavitates, and cavitation eats an impeller in a week. A camlock on the discharge lets the nurse tank hose come and go without a wrench. The manway stays shut between fills so rain stays out of the solution, the wall carries the product name and the date of the last delivery, and the headspace wall gets a look with a light each time the lid comes off. Where winters freeze, drain the outlet valve and the first pipe run before the ground does, or trace them; the body ices from the top down without harm.

Beyond the barn: water, reuse and the fire reserve question

A co-op holding a nitrogen solution, a grower with a carrier water tank at the mix pad, a dairy with a wash chemical under a low roof, and a small water system with hypochlorite in a building whose ceiling stops at eleven feet all buy this shell. It stores water well inside its rating, though a fire reserve is designed to a different set of rules, which the fire-water reservoir design guide sets out. Where a reuse system stores a treatment chemical or a quality-banded stream between stages, the industrial water reuse tank topology article shows where a 5,500 gallon vertical fits.

A permitted load from Lincoln or Philippi

The 7000000N40 ships from Lincoln, Nebraska or Philippi, West Virginia as freight at class 300 as the sheet lists it; at 120 inches across and 132 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 loader with forks long enough to reach under the body sets 1,155 pounds on the pad; straps go under the tank, never through the manway, and never around the fittings. Water first: fill it to the manway, hold it a day, watch the pad edge and the outlet fitting, then drain and dry before the first product arrives. Photograph the outlet fitting from below before the pipe goes on, so a weep next spring has something to be compared against. Walk the base after the first hard rain; a pad that shifts shows it at the edge first.
