Snyder Industries 4600 Gallon ASTM XLPE Black Heavy Duty Vertical Storage Tank

Chowchilla, California and the western lane

Chowchilla sits in the Central Valley, and that is where this tank is molded and where the truck starts. For a buyer in California, Nevada, Arizona, Oregon or Washington, a Valley origin is the difference between a regional haul and a transcontinental one on a shipment 120 inches square, which is the widest footprint in this batch and the one a carrier handles with the most care. The sheet gives freight class 300. Ask the question early, because a ten foot wide shipment is priced and scheduled differently from a tall narrow one, and the answer changes which shape of 4,600 gallon tank you should buy at all. Once it is on the pad the shape pays you back: 116 inches tall is under most eaves, most purlins and most chemical building roofs, and the whole tank can be worked from a short ladder. What it costs you is floor. Full of water this tank is 38,364 pounds and at its rating 72,892 pounds of contents, all bearing on a 120 inch circle through a rotationally molded floor that carries on its entire base, so the slab is engineered to the concrete pad sizing guide, level and in full contact, with no low corner for a wide tank to lean into, inside a berm sized to the tank where the liquid is regulated. Run the volume through the tank sizing calculator against the draw and the delivery interval, and take the reserve and the thermal freeboard from the tank sizing guide.

The 7000500 shell and the wide 4,500 beside it

All four parts in this shell weigh 1,450 pounds and measure 120 by 116 inches, so the sheet's rating is the only thing separating them, and this is the one rated 1.9. Buy it when the liquid is denser than water and the roof is low, because that pair of conditions rules out almost everything else at this volume: the other three grades are rated as their own sheets say, and a lighter rating cannot be talked into carrying a heavy liquid. The alternatives change the footprint instead. The 7000400N29 spreads 4,500 gallons across a 143 inch circle at 91 inches tall and is listed at 1.35 SG on its own sheet, for a site with even less height, and the 8210000N40 stacks 4,650 gallons to 154 inches on a 102 inch base when floor is scarce and headroom is not.

Two rows look the same? The difference is the wall; call 866-418-1777 with the liquid and we will say which, or ask for a quote on both.

A manway at 116 inches, reached from a short ladder

• Access: the manway sits at the top of a 116 inch shell, nine feet eight inches off the pad, which is the shortest climb to a lid in this group. The sheet gives it as an 18 inch threaded vented manway and, on the served spec, as a manway with 15 inch access; both are printed as the sheet gives them.
• Climbing and rigging: ladder lugs and 8 lifting lugs are on the sheet, with 2 flange lines. Straps go under the body for the pick, never through the lid.
• Draw-off: the outlet field reads 1 Manway / Lid, so the sheet gives no separate outlet. Name the liquid and the duty at order and the bottom connection, its material and its gasket are specified then; nothing about a pipe size is implied here.
• Fill and vent: dip tube to the floor, vent sized to the delivery pump, run outdoors on a fuming liquid.
• Service limit: 140 F / 60 C. Warranty: 3 years.

Nine feet eight inches to the lid is the number that makes this tank cheap to own. A short fixed ladder and a small platform do the whole job, a fill line and a vent clear the top inside most buildings, and a person can open the manway, look inside and close it again without a permit and a spotter. The cost of that low profile shows up in head: with under ten feet of liquid above the bottom connection there is less standing pressure to keep a transfer pump flooded, so the pump belongs below the tank bottom where gravity primes it, the suction line stays short and straight, and a low-level float stops the pump before it draws air rather than after. Because the lid is easy to reach, the temptation is to open it often; keep it shut between deliveries so vapor stays in and rain stays out, write the one liquid's name on the wall, and put a light on the headspace band each time it is open.

Dense liquid under a low roof

The site that needs this tank has a ceiling and a heavy liquid: an acid or concentrated solution inside a Valley chemical building, a dense process liquid at a food plant with purlins at ten feet, a heavy blend at an agricultural supplier working under a shed roof. The 1.9 rating and the 72,892 pound contents figure are why this wall exists, and crosslinked polyethylene is what suits it to aggressive chemistry rather than to volume alone; the crosslinking and chemistry duty guide lays out where crosslinking earns its price and where it does not. Water is comfortably inside the rating, but a fire reserve is a different engineering exercise with its own sizing and freeze-protection discipline, and the fire-water reservoir design guide is the place to start on that. If the liquid is ordinary and the building is low, one of the lighter-rated grades in this shell is the cheaper honest answer.

California out at class 300, ten feet wide

It ships LTL from Chowchilla, California at freight class 300 as the sheet lists it, shipped 120 inches by 120 inches by 116 inches, and the freight cost estimator prices that lane to your ZIP. The listed price is before freight. A ten foot shipment is a load the carrier handles outside the ordinary trailer profile, so plan the unloading before delivery day: a forklift with long forks or a crane, straps under the body through the 8 lifting lugs, and nothing taken on the manway. Water test it to the manway, hold it long enough to walk the pad edge and the bottom connection, then drain and dry before the liquid arrives. On a tank this wide, save the pallet it came on, because the next time it has to move it will move on that pallet or not at all. Mark the vent and the outlet on the outside of the shell so nobody caps the wrong one in the dark.
