Snyder Industries 4600 Gallon HDPE Vertical Liquid Storage Tank with ASTM Certification

A tanker load, certified, in the middle wall

A water-rated wall is for water and nothing heavier; the chemical wall is what concentrated acid needs; a 1.5 wall is the middle, sized for brine, fertilizer solution and coagulant as delivered and every water application, with margin, and 1,450 pounds of resin is what that takes on this wide shell. The certification is against ASTM D1998, and the way a tank meets it is in the wall; the HDPE tank wall thickness guide explains the sizing logic and why the headspace is where a wall ages, and the freeboard sizing guide works out the usable volume once thermal expansion is accounted for. Full, it puts 57,546 pounds on a 120 inch circle at the rating: an engineered slab bearing under the entire floor, sized by the concrete pad sizing guide, with the empty tank strapped against wind. The tank sizing calculator tells you whether 4,600 gallons covers the draw, and the tank sizing guide covers days of supply.

Grades on the 120 x 116 inch tank, and the sizes beside it

The N45 is the certified 1.9 wall at this tank's weight for ferric at strength and the heavy brines; the N40 and N42 are cross-linked polyethylene for oxidizers, and the N46 another linear grade. The 7000400N43 is this same 1.5 wall, certified, laid down to 91 inches on a 143 inch base for a barn roof, and the 8210000N40 stands 4,650 gallons of cross-linked resin on a 102 inch base at 154 inches for a smaller pad.

Fittings and access

• Access: 18 inch threaded, vented manway, 116 inches up; filled by truck through a dip tube, vented outside on anything that fumes, and size the vent for a tanker's unload rate.
• Outlet: name the liquid when ordering so the bulkhead fitting matches it; flex at the bulkhead, an expansion joint after it, and the valve braced off the slab so the fitting carries nothing.
• 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 float switch at low level shuts the pump off before it runs dry. The pump sits below the outlet so it primes by gravity; the manway stays closed; a light-sensitive liquid stays out of the sun. If winters freeze, wrap or drain the outlet valve and the first pipe run.

The first delivery

The driver's pump can deliver faster than the manway vent can breathe, so the vent is sized for the unload rate or the fill goes through a dedicated top bulkhead with its own vent line. Run the fill pipe to the floor so the liquid does not free-fall and foam. Watch the first delivery from the first gallon to the last, checking the slab edge and the outlet fitting as the level rises, and every delivery after that goes in the log with a date and a strength.

Jobs it is bought for

Coagulant, brine and fertilizer solution delivered by tanker at plants and farms that need the certification on file, well storage for a community system, and a fire reserve of the kind the fire-water reservoir design guide describes. One liquid per tank, labeled.

What the carrier needs from you

At 120 inches across and 116 inches long on the deck the 7000500N43 is oversize freight (NMFC 156600) on a flatbed at a lane rate; the freight cost estimator gives the flatbed number for your ZIP, and the listed price is before freight. A crane or a forklift with long forks sets 1,450 pounds on the slab. Water to the manway once, a hold, the outlet fitting checked, and the certification paperwork filed with the job. Note the pad height and the outlet height on the site plan while the tape is out; the next pipe run will need both.
