Snyder Industries 5000 Gallon XLPE Vertical Liquid Storage Tank with ASTM Certification

What cross-linking buys at 5,000 gallons

Linear polyethylene softens with heat and creeps under sustained load; cross-linked polyethylene is molded with a catalyst that ties the polymer chains into one network, so it holds its shape under a dense liquid, resists the stress cracking oxidizers cause, and tolerates heat, which is where the higher service limit comes from. The trade is that it cannot be plastic-welded, so any added port is a bulkhead through a drilled hole, decided before the tank is filled. It carries 100 pounds more resin than the linear tanks in this shell. The certification is against ASTM D1998; the HDPE tank wall thickness guide explains the sizing logic and why a tall wall is inspected in the headspace, where hypochlorite vapor does its work. The 5,000 gallon vertical tank buyers guide compares the shapes at this volume across makers; the tank sizing calculator sizes the tank from feed rate and delivery interval; the tank sizing guide covers the reserve, which for hypochlorite is sized for short turnover.

Resins on the 102 x 154 inch tank, and the sizes beside it

The N40 is the lighter cross-linked wall. The N45 and N43 are the linear twins at 1.9 and 1.5 specific gravity, for chemicals that do not attack a linear wall, at a lower price. The 5480000N40 stands 4,900 gallons on a 90 inch base 48 inches taller in cross-linked resin, and the 32372 is the heavy-wall 5,100 on this base, 5 inches taller.

Outlet and manway

• Access: 18 inch threaded, vented manway, 154 inches up; vent outside on hypochlorite and acid service, fill through a dip tube, and size the vent for a tanker's unload rate.
• Outlet: specify the bulkhead fitting for the chemical when ordering, and decide any added port before the tank is filled, because XLPE cannot be welded; a flanged transition, an expansion joint, and a valve supported off the slab.
• Service limit: 140 F / 60 C.
• Listing: ASTM certification.

Hypochlorite is hard on wetted parts, so the level sender is chosen for the chemical, and the tank is shaded; hypochlorite degrades with heat and time, so it is bought at short turnover. Full, the tank loads a 102 inch circle to 79,230 pounds at the rating: a slab engineered for it and in full contact under the whole floor, and straps on the empty tank against wind, and the manway reached from a fixed platform. A single wall tank of regulated chemical needs a berm sized to its volume. With water in it, a 5,000 gallon tank is a fire reserve of the kind the fire-water reservoir design guide describes, though a tank bought in this resin is bought for chemical.

Who buys this tank

Hypochlorite bulk storage at water plants with a berm, acid and warm process liquids at plant scale, and any 5,000 gallon vessel where the chemical would finish a linear wall in a few seasons and the certification has to be on file. One chemical per tank, labeled for both inspectors at once, manway closed against vapor loss.

Delivery day

At 102 inches across and 154 inches long on the deck the 1002100N42 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 or a small crane sets 1,050 pounds on the slab. Water-fill it once to the manway, hold it, and confirm the outlet and manway are dry before the first chemical goes in. Keep the delivery paperwork with the tank; the serial number on the shell is what a warranty claim starts from.
