Snyder Industries 446 Gallon 304 Stainless Steel Supertainer IBC Tote Tank

Choosing 51303 against 51307 and 32210

Three part numbers on this sheet describe 446 gallons on a 42 by 48 by 59.25 inch shell at 542 pounds: this 6984400B51303, the 6984400B51307 and the 6984400B32210. There is no published difference among them at all. That is not a gap in our description, it is what the record says, and inventing a distinction would be worse than useless because it would be quoted back as fact. The practical discipline is short. If a drawing, a spares list, a purchasing standard or an existing fleet names 6984400B51303, order 6984400B51303, put that number in the asset register, and ask us to confirm the record against the part before it ships. Standardising on one number across a site is worth more than any difference you might guess at, because a fleet of identical vessels with three part numbers on them becomes unmanageable the first time somebody orders a spare. The decision that does have engineering content is the size either side. The 350 gallon 6984300B32224 is 47.25 inches and 469 pounds, and the 550 gallon 6984500B32213 is 71.25 inches and 612 pounds, both on this identical 42 by 48 inch plan. The floor never changes across the range, so what you are buying with each step is height, and what you are paying is reach and clear space above. At 59.25 inches this vessel is the middle of that ladder: taller than a tote you can lean into comfortably, shorter than one that needs a designed access platform. Put your delivery quantity through the tank sizing calculator before you assume the middle is right, leave the headspace the tank sizing guide asks for, and if the tier itself is unsettled, the container against tank buying guide is the better starting point than a size chart.

The 446 group and the sizes either side

Ignore the first column for a moment and read the last three. The plan is 42 by 48 inches on every row without exception. The height goes 59.25, 59.25, 59.25, 47.25, 71.25. The weight goes 542, 542, 542, 469, 612. In other words this family gives you one footprint and a ladder of heights, and every purchasing decision inside it is a decision about vertical space and lifting weight, never about floor area. That is unusually convenient when a site grows: the bund, the rack position, the aisle and the forklift approach you commit to today still work if you move up or down the ladder in two years. Within the 446 group there is nothing to separate the three listings on the published record, so pick one number and stay on it. Between the rungs, the arithmetic is even: roughly a foot and roughly seventy pounds per step, for close to a hundred gallons each time. Survey before you choose. The clear height over the intended position, the opening the vessel passes through, and the height your truck can place a loaded tote at are the three measurements that settle it, and the largest tote those three allow is almost always the right buy.

Neighboring size a better fit? Every row links to its own page; freight to your ZIP is quoted on each, or call 866-418-1777.

What breathes, what fills and what drains

• What breathes: the 22 inch manway is listed as vented. That path is how air replaces the 446 gallons going out through the 2 inch valve, and it is the first thing to check when a vessel is emptying more slowly than it used to. Never blank it off.
• The air space above the liquid: fill to a marked working level rather than to the manway, so there is room for warming and for a product that gasses, and so somebody can still take a sample.
• What fills: a 2 inch access port as the inlet, exactly as the sheet lists it. Tell us what your delivery hose ends in and we will confirm the coupling arrangement against this part number.
• The opening itself: 22 inches of manway takes a wash head, a lance, a strainer basket and an arm with a light. That is what makes a returnable steel vessel worth its 542 pounds instead of something thrown away.
• What drains: a 2 inch 316 stainless ball valve at the bottom of a 59.25 inch vessel. Whatever hangs on it gets its own support, and a flexible connection goes in at the first joint if a pump follows.
• Limits: the sheet publishes no service temperature, no warranty term, no pressure rating and no stacking load, so this page asserts none of them.

Where the 2 inch valve feeds a dosing skid rather than a hose, design the frame, the containment tray and the leak detection alongside the pump rather than after it; the pump skid design guide for tank-fed dosing takes them in the right order.

Where 446 gallons is the right size to buy

This volume suits plants whose working quantity was set by a recipe or a delivery schedule rather than by a packaging catalogue: beverage, dairy and ingredient production, brewing and distilling, cosmetics and personal care blending, ink, coating, resin and adhesive manufacture, plating and surface treatment chemistry, and pilot lines scaling a formulation towards production. It is also the size a site settles on when the tallest tote in the range will not go where it needs to go. The duty that pays for stainless is always the same one: the vessel is emptied, washed, inspected and returned to service, year after year, instead of leaving the site. Look the product up in our chemical compatibility lookup before ordering, so the gasket at the 22 inch manway and the seat in the valve are specified on the chemistry rather than on the tank.

One shipment, 542 pounds, no NMFC number

The sheet gives the freight class as 125 and carries no NMFC number and no plant at all, so this page names no shipping point and no lane. Price the move to your ZIP with the freight cost estimator; the listed price is before freight. It ships as one dense unit on its own 42 by 48 inch plan at 59.25 inches, which routes easily and loads beside other freight rather than dictating the trailer. Take it off with a forklift under the base at 542 pounds; never lift it by the 22 inch manway, never sling the body, and keep the forks away from the 2 inch valve. Set it on flat, continuous, level support in the place it will live before anything is plumbed to it, then fill with clean water and hold the 3,720 pound load while you check the manway seal, the access port and the valve joint, and again the next morning. Where the vessel holds a regulated waste, the secondary containment rule for hazardous waste tank systems sets out the leak detection options and the inspection cadence. Stencil the part number on two opposite faces before it goes into service, because on a fleet where three listings look identical, the one you cannot read from the aisle is the one that gets filled wrong. Once it is full and holding, leave it alone for a day before the plumbing goes on; a settled tank is a quiet one.
