Snyder Industries 3000 Gallon HDPE Vertical Liquid Storage Tank with ASTM Certification

Buying the wall the liquid needs, certified

A tank's specific gravity rating is the density of the heaviest liquid its wall is sized to hold for its service life, and most of what a small plant stores sits well under a 1.35 wall, so this grade carries water, brine and hypochlorite as delivered with margin at 510 pounds of resin. The certificate cites ASTM D1998, and what it certifies is the wall; the HDPE tank wall thickness guide explains the sizing logic and why a tall wall is inspected in the headspace, and the freeboard sizing guide works out the usable volume once thermal expansion is accounted for. Full, it puts 35,028 pounds on a 90 inch circle at the rating, which a slab in full contact carries, and the empty tank is strapped against wind. The 3,000 gallon vertical tank buyers guide compares every maker's version of this volume; the tank sizing calculator tells you whether 3,000 gallons covers the draw, and the tank sizing guide covers days of supply.

Grades on the 90 x 127 inch tank, and the sizes beside it

The N33 is another grade at this tank's weight, and the C34 and C37-BLACK are the general-grade tanks in white and black, 65 pounds heavier. The 7410000N39 is this same certified 1.35 wall laid down to 96 inches on a 102 inch base for a low roof, the 8390000C26 the general 2,650 in that low shape, and the 32288 the 3,500 gallon step up on a 96 inch base at nearly this height.

Outlet and manway

• Access: 18 inch threaded, vented manway, 127 inches up; hose or truck fill through a dip tube; vent outdoors on a fuming liquid.
• Outlet: tell us the liquid when ordering and the bulkhead fitting is matched to it; flex between the bulkhead and hard pipe, and a valve braced off the pad so the fitting carries no pipe weight.
• Service limit: 120 F / 48 C.
• Listing: ASTM certification.

The white wall shows the level in daylight; fit a sender read at ground level so nobody climbs for a number, and a low-level float switch keeps a pump from running dry. On hypochlorite, shade the tank and buy at short turnover. Where it freezes, insulate or drain the outlet valve and the first length of pipe; the body takes ice from the top down without harm.

Who buys this tank

Well storage, hypochlorite or brine at a small plant that needs the certification on file, a rain cistern under a large roof, and a fire reserve of the kind the fire-water reservoir design guide describes. One liquid per tank, labeled.

Delivery day

At 90 inches across and 127 inches long on the deck the 5130000N39 is oversize freight (NMFC 156600) on a flatbed at a lane rate; the freight cost estimator prices the lane to your ZIP; the figure listed here is before freight. A forklift with long forks sets 510 pounds on the pad. Strap it, fill it to the manway once, hold it, check the outlet fitting, and keep the certification paperwork with the project file. Keep the delivery paperwork with the tank; the serial number on the shell is what a warranty claim starts from.
