Snyder Industries 1100 Gallon XLPE Vertical Liquid Storage Tank with ASTM Certification

Cross-linked, low and certified

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. 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. The certification is against ASTM D1998, and the HDPE tank wall thickness guide explains the sizing logic and why inspection happens above the liquid line. The low shape cannot tip, keeps a pump suction flooded to the last few inches, and puts the floor a hand's reach through the manway; the cost is 86 inches of floor in full contact with a level pad carrying up to 17,431 pounds at the rating. The tank sizing calculator and the tank sizing guide settle the volume against feed rate and delivery interval.

Resins on the 86 x 55 inch mold

The N45 is the linear-resin twin at the same weight with the same certification, for milder chemicals and a lower price; the C26 is the lightest wall in the shell at 160 pounds. The 60 inch tanks are the same volume stood up, 34 and 54 inches taller on a base 26 inches narrower, for the room with height and no floor.

What is fitted

• Access: 18 inch threaded, vented manway, at waist height; vent outside on hypochlorite, acid and caustic, fill through a dip tube.
• Outlet: specify the bulkhead fitting for the chemical when ordering; a flexible transition to the pipe and a valve supported off the floor.
• Service limit: 120 F / 48 C.

A 55 inch range is easy for any level sender, chosen for the chemical since hypochlorite is hard on wetted parts. Mount the dosing pump below the outlet so it primes by gravity, give the vent a line routed away from the pump's electrical gear, and shade the tank; hypochlorite degrades with heat and time, so buy small lots often.

Applications

Hypochlorite bulk tanks at water systems with a low chemical room, acid and caustic make-up tanks on skids and trailers, and any 1,100 gallon vessel where the chemical would attack a linear wall in a season. With water in it, one unit of the fire reserve the fire-water reservoir design guide describes, with a wall that will outlast a water tank's.

On the truck

At 86 inches across the 1710000N42 is still LTL freight (NMFC 156600-01), palletized, at a class rate the freight cost estimator shows for your ZIP; the listed price is before freight. Two people and a pallet jack take 180 pounds off a liftgate. Water-fill to the manway and hold it before the first chemical goes in, confirm the outlet and manway are dry after the hold, and keep the certification with the project file. Mark the vent and the outlet on the outside of the shell so nobody caps the wrong one in the dark.
