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

Sixty-three tons of chemical on a ten foot circle

A 1.9 specific gravity wall is sized for a liquid nearly twice as dense as water, and 2,300 pounds of resin is what that takes at 8,000 gallons, 400 pounds more than the certified 1.5 wall in the same mold. The certification is against ASTM D1998; 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 126,768 pounds on a 120 inch circle at the rating: a slab designed for the load and in contact with the whole floor, as the concrete pad sizing guide, inside a berm sized to the tank, with the empty tank strapped against wind at two heights and the manway reached from a fixed platform with a rail. The tank sizing calculator matches the volume to feed rate and delivery interval, and the tank sizing guide covers the reserve, which for a dense chemical includes freeboard for thermal expansion.

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

The N43 is the certified 1.5 wall in this same shell, 400 pounds lighter, for coagulants and brines that never approach this density; the N42 is the heavy cross-linked tank at this tank's weight for the densest oxidizers, and the N40 and N46 the lighter grades. The 7370000N45 is this same certified 1.9 wall at 7,900 gallons, 9 inches lower, and the 7400000N45 at 8,500 gallons, 8 inches taller, in a much heavier shell.

Ports and access

• Access: 18 inch threaded, vented manway, 186 inches up; on acid or caustic the vent goes outdoors, the fill goes down a dip tube, and the vent is sized to the tanker pump.
• Outlet: specify the bulkhead fitting for the chemical when ordering; a flanged transition, an expansion joint, and a valve supported off the slab.
• Service limit: 120 F / 48 C.
• Listing: ASTM certification.

A sender matched to the chemical, read at ground level, means nobody goes up for a reading; a closed manway keeps the vapor in, and a light-sensitive chemical gets shade. Regulated chemical in a single wall tank means a berm sized to the tank around it. If winters freeze, wrap or drain the outlet valve and the first pipe run.

Receiving a tanker

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. The fill pipe runs to the floor so caustic or coagulant does not free-fall and foam; on a shell this tall that is a long drop. A dense liquid heats when water is added to it, so a batch tank is filled with water before the chemical, never after. The first delivery into a new tank is watched from start to finish, with the slab edge and the outlet fitting checked as the level climbs, and each delivery after it is logged with its date and strength.

Typical duty

Ferric and other dense coagulants at a plant with a berm, acid feed for pH control, heavy brine at plant scale, dense process chemicals delivered by tanker with a full reserve, and water where the buyer wants the heaviest certified wall for a long life outdoors, including a fire reserve of the kind the fire-water reservoir design guide describes. A single chemical per tank, labeled once for both inspectors.

Freight to your ZIP

At 120 inches across and 186 inches long on the deck the 5300600N45 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 sets 2,300 pounds upright on the slab; a forklift can unload it but not stand it. One water fill to the manway, a hold, a drain and a dry-out come before the chemical is piped in, and the certification paperwork stays with the project. A photo of the tank on its pad, full, on day one is worth keeping; it is the baseline every later inspection is compared against.
