Snyder Industries 8000 Gallon HDPE Vertical Liquid Storage Tank with ASTM Certification

Fifty tons of contents, certified, in the middle wall

A water-rated wall is for water and nothing heavier; the heaviest wall is for concentrated acid; a 1.5 wall is the middle, sized for brine, fertilizer solution and coagulant as delivered and every water application, with margin. 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 wall this tall is inspected from the top, in the headspace. Full, it puts 100,080 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 at two heights and the manway reached from a fixed platform with a rail, never a ladder. The tank sizing calculator tells you whether 8,000 gallons covers the draw, and the tank sizing guide covers days of supply.

Grades on the 120 x 186 inch tank, and the sizes beside it

The N45 is the certified 1.9 wall in this same shell, 400 pounds heavier, for ferric at strength and the heavy brines; the N40 and N42 are cross-linked polyethylene for oxidizers, the N42 the heavy wall, and the N46 another linear grade at this weight. The 7370000 tanks hold 7,900 gallons on this base 9 inches lower, the N43 this same certified 1.5 wall, and the 7400000N40 stands 8,500 gallons of cross-linked resin 8 inches taller.

Outlet and manway

• Access: 18 inch threaded, vented manway, 186 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: tell us the liquid when ordering and the bulkhead fitting is matched to it; a flexible connector between the bulkhead and hard pipe, an expansion joint, and the valve supported off the slab.
• Service limit: 120 F / 48 C.
• Listing: ASTM certification.

On a tank this tall nobody reads a level by eye; fit a sender read at ground level, and a low-level float switch keeps a pump from running dry. Mount the pump below the outlet so it primes by gravity, keep the manway closed against vapor loss, and keep the tank out of direct sun where the liquid is light-sensitive. 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.

Taking a tanker load

A tanker unloads faster than the manway can breathe, so the vent is sized for the pump or the fill takes a dedicated top bulkhead with its own vent. The fill pipe runs to the floor so the liquid does not free-fall and foam; on a shell this tall that is a long drop. Watch the first delivery from the first gallon to the last, checking the slab edge and the outlet fitting as the level rises, and the log takes the date and strength of every load that follows.

Who buys this tank

Coagulant, brine and fertilizer solution delivered by tanker with a full reserve, at plants and farms that need the certification on file, well storage for a community system, a reserve inside a tall process building, and a fire reserve of the kind the fire-water reservoir design guide describes, where the height gives a pump a flooded suction. One liquid per tank, labeled.

Delivery day

At 120 inches across and 186 inches long on the deck the 5300600N43 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 crane sets 1,900 pounds upright on the slab; a forklift unloads it; only a crane stands it. Fill to the manway, hold, inspect the outlet fitting, and keep the certificate where the project file lives. Keep the delivery paperwork with the tank; the serial number on the shell is what a warranty claim starts from.
